Following on from this thread Michael started.... ....in a blatant act of plagiarism, I purchased the same dual mount adaptor and additional TS Vixen clamp for my Giro-WR. To fit the adaptor properly, I needed to add 4 spacers made from a plastic milk bottle, and it now works very well. In addition, whilst playing around with the various pieces, I replaced the lightweight shaft in the Giro-WR with a 13cm Stainless Counterweight shaft. This adds a little weight, but the result feels much better; smoother motion and I'm sure it will cope with heavier weight. I can swap back at any time so no permanent alteration has been done. I also found that I could arrange it so I can add a counterweight shaft extension plus weight without removing the clamp, making the whole thing much more flexible for single and dual scope use. Very pleased, and grateful to @michael.h.f.wilkinson for the idea Note to self, must get a smarter looking CW, or paint this one!
I am trying to plan out my longer term equipment strategy, rather than go for impulse purchases and would like some advice on dual mounting scopes. At present I have a roll-off shed with steel pier in concrete block. The mount is an HEQ5-Pro, stellar tuned and belt driven which is supposed to have an astrophotography payload of around 11Kg. My main camera is an ASI294MC. Guide camera Lodestar x2. I switch between two scope set ups. (Weight for both includes cameras and filter draw.) • ES102 with 50mm guide scope, FL=714, weight is 7.5 Kg • C8 (not edge) with 6.3 FR and OAG, FL = 1260, Weight is 8kg So clearly I cannot mount both on my HEQ5 Pro. One of the reasons for going with a fixed pier in a shed is that once set up and aligned, I can just push back the roof, align, focus and get imaging in 5 mins. However as targets change I need to swap scopes, rebalance, rewire etc. Not a massive effort but I am wondering if I could dual these scopes and perhaps eventually add something like a WO GT71 FL= 420, weight 2.93 for the wide stuff. So total weight around 19kg. Then maybe in the future go for a Mono camera and filter wheel and even perhaps an C9.25 Edge pushing the weight to around 23kg. To do this I would plan to buy a CEM 60 mount that claims a payload of 27.2 kg, although it is not clear if this is imaging, although I can’t see why anyone would buy one just for visual. I would then just guide with the OAG. So I have two questions: Is this a realistic strategy or would I loose guiding accuracy by loading the mount in this way. Perhaps even compared to keeping the HEQ5-Pro and swapping when necessary. Or maybe just forget the GT71 and C9.25 If I do go down this route, what is the best way of dual or triple mounting? I have read that mounting two dissimilar scopes side by side risks unbalancing the setup, but also that mounting the ES102 on ADM rings risks flexure. Any other advice or observations most welcome.
