I'm currently planning on building my first AP rig. I already have a ZWO ASI294MC camera, so I'll like to pair a decent telescope. Also, I'll like to set it up in my backyard and operate it from inside my house as well as take it to dark sky locations. My buget is between $6000-$8000. Here is a list of the components that may work for this build. Please tell me what you think and if this list needs to be modified.
Scope: Stellarvue SVX080T-3SV Premier Apochromatic Triplet Refractor ~ $1995
Focuser: Moonlite CFL 2.5" crayford with high res stepper motor and mini V2 controller ~ $785
Mount: CEM60EC with the Tri-Pier ~ $4500
Guider: Stellarvue F50 50mm Guidescope ~ $150
ZWO ASI174MM Mini Monochrome ~ $499
Last: QHY PoleMaster Electronic Polar Scope with mount adapter ~ $299
Honestly, that's a great setup, as is. Experienced imagers here will tweak it according to their personal taste, but it's fine as is.
That said, here's this experienced imagers tweaks. <grin>
If you're going to guide (and you should) there's little advantage to the EC version. Certainly not $2000 worth.
I use a 174 to guide. It's a nice luxury. Many suitable guidestars in the most star poor regions. You can also use it to take very nice images of the Moon. Like this.
If you ever get an off axis guider, it works well for that. "Future-proof".
The Polemaster (or, significantly moreso, an iOptron iPolar) is silly easy. At your budget, why not? Any of these are "good enough" for any imaging, performance is not an issue.
The comment about mounting the guidescope very solidly is important. This guy has everything you could possibly need.
I've saved the best for last. <smile> This book will be extremely useful, my copy is well worn.
