I totally support the 294 selection. Given your potential interest in AP, be sure to spring for the cooled version. Even for EAA, the cooled version will help minimize hot pixels and allow you to build a library of master darks ahead of time so you don’t have to do one every night.
Regarding remote, inside, viewing, don’t underestimate the complexity of getting this set up. You’ll need adequate horsepower in your outdoor computer that’s connected to the mount and cameras (probably you’ll want to set up a digital finder) and you’ll need good wifi/bandwidth for managing the image transfers. I’d strongly recommend you search out posts by Noah4x4 on CN and follow his recommendations. There are also posts by cmooney91 and nic35 that are particularly helpful.
Here’s a quick list of issues you should be aware of:
- initial outdoor alignment of your AZ or EQ mount
- initial outdoor focusing followed by indoor focusing as temperature impacts focus
- cheaper options exist but consider a flexible Intel Nuc for your scope-side computer.
- if you’re a Mac person, look into ASIstudio to see if that’s a viable option for observing for you in lieu of Sharpcap...I’m not sure that software is ready for prime time...others may comment
- Plan on what computer you’ll use to remote into the scopeside one and what software will establish a robust connection to scopeside
- you’ll need to decide how you’ll drive the mount from inside and set the scopeside to have all the software needed. (I’m using Cartes do Ceil but this, as all programs like it, requires a fair amount of setting up to display things as you like them and to function correctly.
- filter wheels make sense for remote observing and require a fair amount of setup to get the backfocus worked out on a Newtonian. It may be easier with your SCT.
Roughing out the list above reminded me of the 6+ months it took me to research and begin to figure out this stuff and I’m still in mid-stream working out my focus wheel and starting to research autofocusers. It’s worth it but don’t under-estimate what’s involved in doing remote observing.
