The classic long focal length Achromat we grew up with, with a modern twist. So if you're up for a nice, relaxed long focal length Achromat with a few modern enhancements, look no further. Available from Altair or your nearest authorised Altair Astro dealer

The longer tube gives the Starwave TM 102 F11 Achromat that classic look. Call it a retro revival if you will, but there's more to this design than meets the eye.

Recommended primarily for planetary, solar and lunar observation, the StarwaveTM 102 Achromat also offers a pleasant high-contrast view of deep sky objects too, and is a great all-rounder to get you into long focal length lunar and planetary observing.

For refractor fans who want a well-made classical Achromatic refractor but with modern optical coatings, a light weight portable tube, enough aperture for planetary details, and a smooth dual speed Crayford focuser, this is the one. 

What's more, the CNC machined tube construction, focuser, and lens optical quality is far superior to the cheap Achromats flooding the market these days. 
Demanding the best from our optical suppliers is what we are best known for, so each lens has been hand-figured in the final stages and a unique serial number is engraved on the lens cell. As part of the unique QC process, each lens is traceable back to the assembly technician and glass batch. These lenses star-test very well indeed as a result. In fact, the star-test for the Starwave 102mm F11 Acromatic refractors is much better than any other achromats we've sampled, even at twice the price, with some rave reviews by customers. Modern multicoatings on all four air to glass surfaces enhance the contrast even further. Even customers who have used Achromats for years are amazed at the image quality delivered by the Starwave 102mm F11. 
Depth of field at the slightly longer focal ratio of F11 helps this lens cut through the seeing, and there is almost no need to rack the focus in and out to "follow" the changes in focal point caused by changes in air density at high powers. This tolerance and easy focusing make the Starwave 102 F11 a nice planetary, lunar or daytime solar observing telescope whilst still keeping it relatively short and light compared to some older achromats. What's more, cooldown time is minimal.
Colour correction is better than the more common fast achromats on the market, and the field of view is remarkably flat in any eyepiece. Your eyepieces don't have to work too hard with this scope due to that long, relaxed focal length and relatively low amount of field curvature.

The 1120mm 'ish focal length gives you plenty of "oomph" magnification-wise, while the tube remains at a manageable length of 1 metre with dewshield retracted, and the weight is very low at only 4.6kg!

We've introduced a "Non-Slip" stainless steel friction plate on the underside of the focuser drawtube for even smoother action.

The Starwave TM 102 Achromat will easily work on your Skywatcher EQ3-2 mount, EQ5 (with slightly better dampening times), or if you're not interested in fiddling about with an equatorial in the dark, (and want something you can just plunk down and use in seconds), check out the rock-solid Altair Sabre TM Alt-Azimuth mount which is lighter, more stable, and a more portable option for field-use. Looks-wise, this fetching combination may even get you "conservatory", or even "lounge" planning consent!

So if you're up for a nice, relaxed long focal length Achromat with a few modern enhancements, look no further. Order your Starwave 102 Achromat here, or from your nearest authorised Altair Astro dealer, all of whom have a showroom. Delivery is £6 UK mainland.

hi guys well i finally got out last night with the altair astro starwave f/11 achro , i took both tripods out the eq5 and the az4 ,armed with my flask of coffee, eyepieces and a baarder minus violet filter , i set the eq5 up and got the scope balanced on it ,the first target i aimed for was vega and got my finder set up . The first thing i noticed was the contrast a rich inky black background and the stars popped out like 3d, the eyepieces i was using was my set of celestron silver top plossls (orange lettering ones) i dropped in a 8mm and checked the collimation and its spot on, then i moved onto the double double and its was spilt showing a well defined space between the pair, my smile started to get bigger then onto m57 its the first time i have found the ring nebula without having to hunt about for it , it stuck out like a sore thumb a smoke ring in the sky, next target was alberio and thats when my smile turned into a grin, someone once said to me that the differance between a achro and a ed/apo was the colours .. well that person needs to look through this scope , the scope gave gold/yellow and a bright blue pairing , and that reminded me of the double star in andromeda " almach " and again the spilt was perfect and the colours were gold/red and blue/white. it was then i realised i had got a excellent scope for doubles i then decided to put a 30mm eyepiece in and have a look at andromeda galaxy and it did not disappoint i put a 18mm in and with averted vision saw some structure to the galaxy and not just the centre core . at this point i went to realign my scope found polaris and found polaris b i put a 8mm in with a tal 2x barlow given 275x appox and had a look the polaris was a tight airy disk and the contrast was still there , so far the scope has gone way beyond my expectations for a achro , cant wait to see the moon/planets is this where it will fail! somehow i dont think so , i will update when i get to see them .
at this point i took it off the eq5 and put it on the az4 , first thing it needs a extension pier i knew it would , but without it you can reach about 80' alt, it takes the weight fine the az4 will take 15lbs with the finder plus eyepiece and a 2" diagonal its about 13lbs and it was a absolute pleasure to use on the alt/az mount i love the the alt/az system over the eq i cant find objects faster than a goto proved it on many occasions at star party's anyway swung it over to the double cluster and that was my wow moment of the night diamonds on velvet thats the best way to sum it up .i also had a bit of fun following a satellite on high power from the north right to the east holding the arm and the end of the scope very smooth action .
on to the mount, with a extension it is quite useable for low power/medium views with a few mods to the az4 its also useable for high power work if you nudge the scope it takes about 2 seconds to settle down. the mods are a weight between the legs on your eyepiece tray and anti vibrations pads under the feet also added a m8 bolt in the spare hole on the mount to secure the scope better .
well this is just a few thoughts on last nights outing the scope is fantastic and you dont need eq5/eq6 to use it , well i brought all my gear back indoors made a coffee and put my hand in my pocket and pulled out the baarder minus violet filter .... i never used it all night ,
thanks for reading and clear skies john.
