I posted this on cloudynights but would like any advice you all could give as well. I've had 2 8" SCTs and now own a 6" SCT for numerous reasons. But now I'm would like to trade it in for a dob. I want something not too heavy though as I have a back problem, ideally under 35 lbs for the heaviest component. My top options are: - Zhumell Z10, but I talked to them and they can't give me a net weight for just the tube though, and the shipping weight for the tube is 50 lbs! - Orion XT10, either intelliscope or not, have to decide. To upgrade the classic to the features that come with the intelliscope it's not far behind in price. But I would have to get scope gripps for adjustable tension; not sure if that's an option for the intelliscope. Both of these are quite a bit more money that the Z10 comparably equipped. Anyway, a couple other options have me thinking. The slower f-ratio of the 8" scopes is attractive to me (less sensitive to eyepieces and collimation). Only Discovery seems to make a 10" f6, and although they are a bit heavier, I think the quality would be worth the money. They have long wait times now though, but I suppose I wouldn't use it as much until summer anyway. OPT sells an 8" f9 that is interesting, but no 10". The other temptations are the Orion XX12i or Meade Lightbridge 12. Initially I didn't want a truss tube, as it would be more hassle to set up and I would for sure have to recollimate every time. I do notice a definite difference between by 6 and previous 8s, and I was hoping to at least get a 10. It is very tempting to double my aperture, but I don't want something that I won't get out because it's a hassle. So what do you recommend? Thanks.
