Ags Posted September 24, 2019 Share Posted September 24, 2019 I have been slowly putting together a flexible setup consisting of a Berlebach Report 112 short tripod, and a Castor alt-az for undriven visual dual scope DSO hunting, and an AZ-GTi for goto and planetary viewing and imaging. I am looking at upgrading my planetary/lunar scope from a Skymax 102 to something a bit bigger that still falls into the grab and go category and can still be carried by the AZ-GTi. I keep coming back to the C6: weighing around 3.8 kgs it would fit in the carry capacity of the mount when loaded up with accessories. At F10 it is a better fit for my ASI178MM camera (2.4 um pixels) than the F13 Mak, and 6 inches of aperture would be much better for planetary imaging. The greater aperture would be kinder on my eyes for visual planetary observing. It would go nicely on the Castor opposite my ST80 for DSO hunting, particularly with 6.3 reducer. But it's a lot of money - am I missing something? Link to comment Share on other sites More sharing options...
Greymouser Posted September 24, 2019 Share Posted September 24, 2019 (edited) Well, if you are, so am I! I do not have the C6 but the C5, along with an AZGTi, ( when it comes back from FLO after attention, because it was faulty, ) it seems to work very well. My only regret is that I did not go for the C6, which is only a little heavier and was the same price. Still is the same price in one place. https://grovers.biz/optics/optical-tube-assemblies/7509-celestron-nexstar-evolution-6-ota.html They have several different versions, not all the same price, even though they each have the same standard optics, I am assured...

dweller25 Posted September 24, 2019 Share Posted September 24, 2019 @Ags You have summed it up nicely. I would add that I wrapped my C6 with 2 layers of reflectix, the views are now much more stable and the corrector takes significantly longer to dew up. 1 Link to comment Share on other sites More sharing options...
Ags Posted September 25, 2019 Author Share Posted September 25, 2019 Yeah, I have heard that trick works well - but it doesn't have the aesthetic refinement I require from my setup 😃 1 Link to comment Share on other sites More sharing options...
RT65CB-SWL Posted September 25, 2019 Share Posted September 25, 2019 (edited) Hi @Ags. Below is an single frame image of Mars I took during the opposition in April 2014... ...taken with an Olympus Camedia C2040, handheld over a TeleVue 6mm Radian + neodymium filter and Celestron C6/SCT from a hotel garden near LHR. Depending on how good your eyes are, or monitor is, there is a teeny-weeny bit of visible surface detail, as Mars was a having a dust storm at the time. Please feel free to save and play about with the image to enhance it. Edited September 28, 2019 by Philip R 1 Link to comment Share on other sites More sharing options...
Ags Posted February 5, 2020 Author Share Posted February 5, 2020 Just revisiting this thread - still not sure the AZ-GTi can take a C6. I have started saving for one anyway 😀 Does anyone have any new thoughts or experiences on the C6 + AZ-GTi combo? Link to comment Share on other sites More sharing options...
RT65CB-SWL Posted February 6, 2020 Share Posted February 6, 2020 Hi @Ags. I think you are close to the maximum load capacity using the AZ-GTi. The payload of the mount is 5kg / 11lb. http://skywatcher.com/product/az-gti-mount/ Link to comment Share on other sites More sharing options...
Ags Posted February 6, 2020 Author Share Posted February 6, 2020 Well, the C6 weighs 3.8 kgs plus accessories, so that should be ok. But it is getting close - that's why I am looking for real-world experiences. Link to comment Share on other sites More sharing options...
happy-kat Posted February 6, 2020 Share Posted February 6, 2020 Could you load up your 102 to that weight and see how the combo feels. Link to comment Share on other sites More sharing options...
Ags Posted February 25, 2020 Author Share Posted February 25, 2020 I don't think so - it's not just the weight but also the diameter and length. I am just going to trust the manufacturer's specs - the AZ GTi says it can take 5 kilos so I'll go with that! Link to comment Share on other sites More sharing options...

I would use it only for observing as well as planetary imaging. Any feedback? 🙂 Link to comment Share on other sites More sharing options...
Ags Posted July 21, 2020 Author Share Posted July 21, 2020 (edited) The setup works very well (aside from an unrelated fault in the AZ-GTi). The mount carries the load well and goto is accurate. Optics are one step below a Maksutov in my opinion but good enough, and in my case much improved on all targets and magnifications with 6.3 reducer. I have had to learn my way round collimation though, but collimating an SCT is really simple compared to a Newt (in my opinion). I have not tried planetary imaging yet but I have been delighted with my results on the Moon with my ZWO ASI 178 MM.

I have the AZ-GTI and am looking at the Celestron C6. But I thought the C6 is 4.54kg. Is there a version that's 3.8kg ? And how have you been with the C6 and AZ-GTI after a couple of months now ?

Ags Posted September 18, 2020 Author Share Posted September 18, 2020 (edited) 3.8 kg is an often quoted value, but that seems to be the weight with a diagonal and random eyepiece. I have weighed just the OTA and I measure 3.3 kgs. Edited September 18, 2020 by Ags Link to comment Share on other sites More sharing options...
-philip- Posted September 27, 2020 Share Posted September 27, 2020 Excuse me for bumping this. I have a skymax 127 on my AZ-GTi and FLO have recommended the C6. I am wondering what will the C6 do that the 127 cannot? Link to comment Share on other sites More sharing options...
Ags Posted September 27, 2020 Author Share Posted September 27, 2020 I expect it would be hard to tell the views in a C6 and Skymax 127 apart unless you had them set up side by side. The C6 would just be a small incremental improvement over the C6 in terms of light gathering and resolution. The main argument for the C6 is it is the biggest aperture you can put on an AZ-GTi. 2 Link to comment Share on other sites More sharing options...
Highburymark Posted September 28, 2020 Share Posted September 28, 2020 I’ve found the AZGTi can take over 5kg quite happily. I use it with my Tak Epsilon 130d, which is 4.9kg without eyepiece/camera. C6 would be no trouble. Glad you’re enjoying yours Agnes - it’s a really nice compromise as a true grab and go but with decent aperture. Maks should be a a little bit sharper, but the C6 is a better all round scope in my view. 2 Link to comment Share on other sites More sharing options...
Ags Posted September 28, 2020 Author Share Posted September 28, 2020 Agree Maks are a bit sharper. I really see the difference on double stars. Link to comment Share on other sites More sharing options...

Though I do not own either the Skymax 127 or the AZ-GTI I too find there is a "...small incremental improvement..." with my C6 and ETX105. (image below).
