Skipper Billy Posted October 23, 2020 Share Posted October 23, 2020 I am starting to think about a significant increase in focal length from my current 530mm setup for imaging.This 10" RC caught my eye but my question is quite specific....My remote observatory is very small and I need to be sure that any new scope will fit inside it!Is anyone using a 10" truss tube RC with a filter wheel, electronic focuser and fairly heavy camera???I would appreciate knowing the overall length of such a setup from the back of the camera to the front of the scope and ideally where the centre of gravity lies so I know what the overhang is forward and aft though this is less important as I can add weight to move the CofG.Specifically I will be hanging off the back of it a Lakeside electronic focuser, Atik EFW3 and an Atik 16200 - I will probably also use an off axis guider with a Lodestar but that doesn't weight much.If anyone is using the exact scope I would also appreciate knowing the distance between the two red lines on the attached photo ie the total overall height.Thanks in advance.

Wyvern Posted October 23, 2020 Share Posted October 23, 2020 I think @silentrunning uses the 12" version of this. Quote Link to comment Share on other sites More sharing options...

silentrunning Posted October 23, 2020 Share Posted October 23, 2020 Hi Skipper BillyYes I have the 12" GSO RC but it's the tube version rather than the open truss and it's really quite a different beast in terms of size from the 10" so I can't imagine any of the required dimensions would match. Let me know though if you want any measurements from scope that I have.All the bestJohn Quote Link to comment Share on other sites More sharing options...
Skipper Billy Posted October 23, 2020 Author Share Posted October 23, 2020 @silentrunning Thanks for that - John Kulin has the identical scope and has given me the measurements but thanks for the offer ;-) 2 Quote Link to comment Share on other sites More sharing options...
Jkulin Posted October 24, 2020 Share Posted October 24, 2020 @skipper-billy The only thing to do now is pay for it ? ? If you send Ian @ AA a message via FB he has a knack of coming up with some absolute gems, I bought mine from him from a client who had never used it at a bargain price, it might save you a few bob.

Skipper Billy Posted October 24, 2020 Author Share Posted October 24, 2020 @Jkulin Sadly it wont fit in my obsy. It will hit the walls when slewing. Will have to have a rethink or wait for MkII observatory when we move house ;-) Thanks for your help though. Quote Link to comment Share on other sites More sharing options...
Gina Posted October 24, 2020 Share Posted October 24, 2020 Oh dear - that's a shame - how sad! I feel for you David. Quote Link to comment Share on other sites More sharing options...
Jkulin Posted October 24, 2020 Share Posted October 24, 2020 @skipper-billy Ah sad news David, what about a really nice Newtonian or will you have the same issues? Quote Link to comment Share on other sites More sharing options...
Gina Posted October 24, 2020 Share Posted October 24, 2020 The only way I know of getting a long focal length in a small space is with a folded light path but I'm sure you know that! Quote Link to comment Share on other sites More sharing options...
