1 TAL Apolar 125: 125mm Apochromatic Refractor Introduction The TAL company is based in Novosibirsk, Siberia, Russia and has been producing telescopes and other accessories for the amateur market since the 1980 s. Since then TAL have maintained a strong following for their range which currently includes newtonians, achromat refractors and a modified maksutov-cassegrain telescope design called a Klevtsov. I bought my first TAL in 1999, a TAL 100RT 100mm F/10 achromatic refractor and was impressed with the optical quality, rugged but effective mechanicals and, not least, the low price!. In early 2010 TAL announced their first apochromat refractor, the TAL Apolar 125 creating more than a ripple of excitement and anticipation both because it was a 5 class apochromat and that it promised an innovative 6 element objective lens design. Nearly a year elapsed before we saw any of these scopes in the UK and I was lucky enough to be invited to review one of these by First Light Optics with the agreement of the TAL importer, OVL. Scope Description The scope is supplied in a solidly made wooden case 122cm in length. The scope is held in place inside by felt-lined wooden braces cut to shape. The finder needs to be removed and has its own little rack to sit in. The lid has 3 stout clasps to hold it firmly shut. Very TAL!.

2 This is a rather distinctive scope and it will certainly stand out in a crowd!. The delicately tapered tube seems to be borrowed from the 125mm achromat that TAL also produces. The diameter of the objective lens cell and the dew shield give away that fact that this is a refractor of some aperture but overall the scope seems more compact and slender than you might expect. Here are the TAL Apolar 125 s vital statistics: Tube Length (inc diagonal) 116cm (focuser racked in) Tube diameter (focuser end) 10cm Dew shield diameter 17cm Dew shield depth (to objective) 15cm Draw tube diameter (internal) - 51mm Focus travel - 12cm Tube weight (stated, inc diagonal and finder) 8kg Clear aperture (measured at front element) 125mm Focal length (stated) 940mm Focal ratio (stated) F/7.5 Focuser single speed crayford type Finder scope 6 x 30 in adjustable mount Supplied diagonal fitting mirror diagonal Instruction Manual - 15 pages UK Retail Price: Around 1,500

3 The innovative optical system uses 6 elements in 3 groups, comprising a 125mm singlet, a triplet and finally a doublet as shown in this stock diagram: According to the design patent, the optics use 2 types of ordinary optical glass rather than ED or similar glass types. There appear to be 3 light baffles between the 125mm singlet and the triplet element with others visible beyond that. The multi-coatings on the outward side of 125mm singlet appear purple and very effective, the glass just seems to disappear from a number of angles.

4 The 125mm singlet lens is set in an adjustable lens cell although it is of a rather different design from the simple push-pull variety that is used on other refractors. The triplet element is located in the centre of the tube, its position marked by 3 partially filled holes on the outside of the tube (2 are just about visible here):

5 I assume that the doublet element is located within the extended housing for the Crayford focuser. There does not appear to be any provision for adjustment of the triplet and doublet elements of the optics which is perhaps just as well as it removes the possibility of well intentioned adjustments upsetting the collimation of what is a rather complex optical system. The tube rings and handle are supplied as integral unit but without a dovetail bar. The spacing of tube rings is not adjustable without removal of the handle and is probably designed to suit TAL mount seats. I had to provide my own Vixen / SkyWatcher compatible dovetail bar to mount the scope on my non-tal mount. The tube ring fastening nuts are fitted with retaining screws and are 17cm apart. The tube rings are lined with green felt and the carrying handle has two ¼ threaded holes, one at each end which could prove useful for attaching further accessories.

6 The white painted tube is finished to reasonable standard but some paint flaws are visible here and there. The join, where tube starts to flare outwards toward objective, is covered by a rubber band underneath which is a welded joint with 3 retaining screws which project 2mm but are hidden by the band. The longitudinal welded tube seam is visible on the bottom side of the narrower tube section and more noticeably on the flared section. Tube is made from heavy gauge metal, 3mm or so thick, which probably accounts for much of the overall weight of the scope (see photo of objective cell above). The metal dew shield is well made and internally ribbed and blackened to minimise glare. It is fixed to the metal cell containing the 125mm singlet lens by 2 screws set at 90 degrees to each other. The dew shield is a tight fit even when these are loosened. The dew shield and other black parts of the scope are finished well in a silk finish with eggshell texture. There was a very thin 8 cm scratch on the dew shield when the scope arrived which had been noted by the importer. With the dew shield removed there is a further machined collar that needs to be slid back to reveal the adjustable lens cell. The supplied dust caps are plastic. The objective end one has a 3cm aperture with a removable cap in its centre although this does come of rather easily and could easily get lost. I m not sure why you would want to stop the scope down to a 3cm aperture to be honest!.

7 The TAL logo is a large sticker on the side of the flared part of the tube and I have to say that looks just like a sticker, which is in common with TAL s other refractors, but I feel does detract from the finish somewhat. The focuser is standard single speed crayford with tension and locking crews underneath. It s focus knobs are 37mm in diameter and well knurled. The focussing action is smooth but firm and I m sure it would hold heavy accessories well however, unfortunately a 2 diagonal uses up more than the available inwards focuser travel and cannot come to focus so the scope is limited to eyepieces with the 1.25 fitting. To me this is a fairly substantial drawback in the scopes design and a somewhat surprising one given the popularity of 2 accessories today. The supplied diagonal is a 1.25 fitting TAL mirror type with what look to be standard coatings. The diagonal has a plastic retention screws that should not mark eyepiece barrels. The supplied adaptor is non-compression ring type but it s set screws have plastic tips to reduce marking on eyepieces and diagonals. The 2 barrel of the adaptor is security tapered rather than undercut but not threaded for 2 filters. Overall this hardware is effective but does have a rather rough finish in places. The 6 x 30 finder scope mount bolts onto the tube with 2 screws there is no quick release dovetail. The finder tube is held in a retaining ring that pivots until locked by single screw. This works slightly less elegantly than it looks but does its job well once set. The finder has a push on plastic dew cap that projects around 4cm beyond the objective lens. I feel the finder is rather small for a scope of this class - you would certainly want to consider adding a good red dot type finder to work alongside it.

8 The finder scope does have a port for fitting a reticule illuminator but the illuminator is not supplied as standard which is a shame because, without illumination, the cross hairs become more or less invisible against a dark sky. The supplied instruction manual is a simple 15 page affair which covers the absolute basics of using the focuser, fitting and aligning the finder and such like. Interestingly, under Telescope alignment (meaning optical alignment / collimation) the manual offers no advice on how to do it but states The telescope alignment should be held by specialists, as it requires special skills and qualification. The translation might be slightly incorrect but the meaning is clear!. On the last page of the manual is the date of issue (04/10 in this case), the serial number (0140) and a signature. Of the overall fit and finish I would say it is typical TAL and around the same as a SkyWatcher Evostar but no better than that. I have a Russian Intes maksutovnewtonian and I have to say that the finish and mechanicals on that are well ahead of the TAL s. There are a number of areas of the TAL which are rather crudely finished to my eyes (eg: the tube seam) but this is balanced by others where the finish is more competent and polished such as the rather nice crayford focuser and the machined dew cap. What the TAL Apolar 125 does have is a unique and distinctive appearance. It s rather longer and thinner than I was expecting for a 5 F/7.5 and also perhaps has a rather dated feel to it rather as if it was manufactured in the 1950 s / 60 s perhaps?. I appreciate that these are subjective views of course and are not necessarily meant as criticisms.

9 Optical Performance I tested the TAL Apolar 125 under the stars on 4 evenings, under a variety of viewing conditions. I would have liked to have done more observing with it but the scopes stay with me coincided with a period of rather poor observing weather. Nevertheless I was able to get a fairly good idea of the optical performance of this particular example at least at high and medium magnification (see below). It is also worth remembering that this is just one example of the scope. For most of my time observing with the scope I was using University Optics Orthoscopic eyepieces. I did use one or two of my Tele Vue Ethe eyepieces occasionally but I was not happy to put such heavy and expensive oculars into the supplied 1.25 diagonal for too long and, as already mentioned above, it was not possible to use a 2 diagonal on the scope due to a lack of inward focuser travel. Because my lower power eyepieces are of the 2 variety it has unfortunately not really been possible for me to explore the scopes capability for low power, wide field observing. During these sessions I was able to compare the TAL Apolar 125 from time to time with my Vixen ED102SS, a 102mm F/6.5 ED refractor and, for a short while, with my Intes 152mm F/5.9 maksutov-newtonian. The scope had cooled for at least 45 minutes before starting observing during each session and I chose to view the following objects with it: The Moon (20% illuminated crescent), Jupiter, Saturn, Rigel, Sirius, The Trapezium group, Sigma Orionis, Castor, Algeiba (Gamma Leonis), Polaris, Porrima (Gamma Virginis), the open cluster M35, the great nebula M42, the globular cluster M13.

10 It s probably easiest to describe the scopes optical performance categorised by object type, so here goes: Lunar The 20% illuminated crescent moon looked superb with the TAL Apolar 125. There was no discernable chromatic aberration (false colour) showing on the lunar limb or terminator areas, either at focus or, either side of it. The TAL clearly has very good colour correction indeed. Using 7mm and 5mm orthoscopic eyepieces (134x and 188x) sharp details, black shadows and high contrast showed off lunar features to their best advantage. Fine details such as rilles, craterlets and domes stood out as did the colour variations across the lunar surface. Planetary Jupiter was getting rather low in the sky and was past its best for this opposition however the TAL Apolar still showed impressive detail on the Jovian disk thanks to the excellent contrast that the scope delivers. A number of darker belts were seen including confirmation of the return of the South Equatorial Belt that had almost disappeared for much of the past few months. As of the 26 February 2011 I can report it has almost returned to its former glory. The planets low altitude was causing a little false colour to show on the planetary limbs but I would put that down to atmospheric diffraction rather than anything induced by the scopes optics. The low altitude also restricted the clarity of other Jovian surface features and the Great Red Spot was hiding around the other side of the planet so there was nothing the TAL could do about that!. The views of Saturn were equally satisfying with the planets more favourable position allowing more power (188x and 235x) to be used. No false colour was showing and the planet was presented as a pale lemon colour. The rings and equatorial belt were well defined but on that occasion I was not able to do any more than suspect the Cassini Division in the rings, although I don t doubt that scope would show it in due course when the planet is better placed. Titan and 3 fainter moons were seen quite easily, magnitude 10.7 Tethys being challenging as it was close to the planet but it popped into view with the TAL without too much searching. While the views of Saturn were very good, I did find that I had to hunt for the sharpest focus position a bit more than I would have expected. The TAL Apolar did not have quite the snap to focus that my Intes maksutov-newtonian has, for example. Multiple Stars The TAL resolved all the multiple stars I have listed above without much trouble as you would expect a good 5 refractor to do. The E & F components of the Trapezium, which can be elusive, were notably clear 125mm is the smallest aperture that I have clearly seen them both with. Rigel s 9th magnitude companion was an easy spot with the false colour on the bright star being controlled to just a tiny splash of purple. The most challenging object here was Porrima (Gamma Virginis) which is a double star with a separation of around 1.6 arc seconds currently but the TAL did show a clear split at 188x.

11 Examining the intra and extra focal star images showed circular and fairly concentric diffraction rings that appeared fairly even on both sides of focus. At focus there was one feature that I found distracting and that was that the scope would not show a tight round airey disk but rather what was seen was a tiny elongated oval. The oval did not switch orientation as you passed through focus so I don t think it was caused by astigmatism. My guess is that it must have been a small amount of coma due to a minor misalignment somewhere in the optical system but I was not able to pin down where. At focus the airey disk did not seem to show a clear first diffraction ring which could be part of the same issue. The above problem did not prevent the scope from performing well on the multiple stars that I observed with it but, if you are fussy like me, it would annoy and it might hamper splitting tight double star with uneven brightness components where the slightly misshapen airey disks could possibly mask the split. Even on Sirius the false colour was very well controlled, as with Rigel, being limited a very small purple haze at focus. Star Clusters The large open cluster M35 in Gemini was very nicely shown with dozens of stars visible across the wide field of my 13mm Tele Vue Ethos eyepiece as well as the condensed and much fainter cluster NGC 2158 clearly seen as 8th magnitude. hazy spot in one of M35 s outlying regions. The view of the globular cluster M13 in Hercules was all you would expect for a 5 aperture scope to deliver. Noticeably more stars were resolved in the outlying regions of the cluster by the Apolar 125 than my Vixen 102 could achieve although aperture really does rule with globular clusters and the view was better again though a 6 scope. Nebulae I was only able to study the great nebula in Orion, M42, during my sessions with the TAL and this object is impressive with even an 80mm scope. The Apolar did a great job at showing the nebulosity and I could trace it s strands over quite a wide area and see nice detail and structure within the area around the Trapezium the fishes mouth as its sometimes called. The TAL clearly has excellent light throughput, despite its 6 lens elements, and also good quality multi-coatings. Summary I feel that the Apolar optical design clearly has a lot of potential and, in the case of this example at least, delivers good performance, but not quite top notch. Optically, the scope did everything that a good 5 refractor should do. Its colour correction was excellent for a F/7.5 refractor not perfect, but very good indeed. It s light throughput and contrast is excellent and it s resolution is as it should be, with the exception of the appearance of the airey disks at focus, which I would have liked to see as circular rather than slightly extended of course.

12 The key point is going to be whether the TAL can produced the innovative optical design with constant quality that will satisfy customers who feel they have invested a substantial chunk of money in the scope. Unlike more conventional objective lens designs, the Apolar optical system is not, in my opinion, very accommodating of fine tuning by owners. Mechanically and cosmetically the scope is typical of TAL very good in some places, rather rough in others. The biggest glitch I came across was the inability of the scope to allow a 2 diagonal / eyepiece to reach focus which is not something that can be worked around as far as I can see so the user is restricted to 1.25 accessories. The finder and finder mount could be better (more aperture in the case of the finder itself). The scope does have character and unique, distinctive looks. From what I have seen of other TAL telescopes, each is likely to vary slightly in execution and finish which will appeal to some prospective owners but can be a double edged sword of course. Many thanks to First Light Optics and OVL for making the scope available to me for this review. John Huntley May 2011
