This is my second or third post in the last month or two in an attempt to solve the quest of what 12 inch Dobson to get to upgrade my trusted 8 inch. I've changed my mind so many times: custom made truss, then Orion SkyQuest 12XXg12, GoTo, manual, and then back again where I started.
The one thing that is not negotiable for me is that the scope must fit in an average car to be transported to a dark site. At the same time, I don't want to have to spend 20 minutes at the end of an observing session, in the cold, disassembling a scope in a dozen different parts. By the time I'm done observing I usually just wanna get home fast!
Anyway, today I found out that Orion Optics UK manufactures an 12 inch F/4 Dob with what looks like a pretty small base and weighs under 30 kg. The optics apparently are 1/8 lambda p/v wave with test report and 97% reflectivity. Here it is: https://www.teleskop...1-8-Lambda.html
The more I think about it, the more it seems to me this could be an ideal solution for me: I can fit it in my car, it's very quick and simple to put together, it's fairly light for a 12 inch, it packs a 12 inch aperture, and has premium optics.
The downsides I've identified are: at F/4 it requires a Paracorr, but to me it's a fair trade off for it's portability; collimation is more critical than on a classic F/5, and certainly much more than in my current F/6 tube.
I was hoping I could get some insight from people who've had fast reflectors on whether - with the right eyepieces - a 12 inch F/4 would perform well on planets and Moon and whether there are other downsides that I'm not considering. Is it a good idea to get this fast scope instead of a truss structure F/5?
Thanks in advance and clear skies to all!
