For Deep-Sky AP of mostly galaxies (and nebulae), what'll give me the best results– a medium-weight 130 P-DS or a very lightweight wide-field WO Z61? I know the "best" telescope is one that doesn't just collect dust all day long, but I just can't figure it out. Supporting said telescope will be the SW HEQ5 PRO Synscan (with the Rowan Astronomy belt attached), which will be supported further by a autoguiding system, possibly a very lightweight CF 32mm refractor with a ZWO ASI 120mm Mini (Can't find the -S model in Japan). On the telescope'll be the Canon EOS 600D, quite a heavy beast IMO. Instead of leaving it here, I'll say (just blurt out) everything I know about these seemingly-equal telescopes. The 130 P-DS, clocking in at F/5, will produce fantastic photos of Nebulae and Galaxies alike, although its aperture will slightly limit the galaxies it'll see. It seems this telescope does particularly well when it comes to imaging M81 or M51, and Nebulae like the Rosette. Its price-performance ratio is basically unbeatable, as it's only 250$ over here in Japan and it cranks out fantastic images. The only addition I'll need will be a F/5 SW-issued Coma Corrector; however, I don't need to worry as I'll be getting one from me mum in a few week's time. The William Optics Z61, which has a slightly higher F number of 5.9. It sports 2 lenses with FPL-53 elements in them, allowing for extremely high contrast images of nebulae like the Rosette, Orion, all that lot. I've previously asked a similar question, and I've been convinced by the answer that "I won't really be able to take images of galaxies other than M31, Andromeda, and M33, Triangulum. So why do I even have this as an option when I could just go with the cheaper 130 P-DS? Well because it's a wide field APO. Everything it supports, whether it be the design to the focuser, is just amazing, so much so I can't emphasise the emotion enough. On Astrobin, I've checked out what kind of images these telescopes produce, and I encountered a problem– pretty much everyone was using everything but the 600D. They all used the fancy Mono-cooled CCDs like the ZWO ASI 1600MM Pro. Clear skies, Leon.
of all the kinds of telescopes, is there any one kind that just flat out is better or do all different kinds do different things better? I'm on the market now to buy my third scope, so i want to see if there is a "best" design, and if not, what kind of scope suits my needs. i don't do astrophotography yet, but i want to at some point. i have a honking big minivan so portability isn't big deal, and anyway my mak is very portable. i have a pretty good budget, i can spend up to $700 on this although i would like to keep it under $600 if i can. i would love specific recommendations, but i also would love just general ideas.
