Thanks, I had just found the description of your setup. In case others are curious:
- Imaging telescopes or lenses: Celestron C8 EdgeHD, Starizona Hyperstar 3
- Imaging camera: ZWO ASI 1600MM-Cool
- Mount: Orion Sirius EQ-G (HEQ5)
- Guiding telescope or lens: Orion Mini Guide Scope 50 mm
- Guiding camera: Orion Starshoot AutoGuider
- Software: Adobe Lightroom , Pixinsight PixInsinght 1.8
- Filter: Baader Planetarium H-Alpha 2" Highspeed
- Accessory: Starizona Microtouch Autofocuser
If I can get your opinion on something. I have a C8 on a wedge mount with early 1990's era electronics. Do you think it's worth re-mounting that tube to upgrade to modern guiding electronics, or would you just sell the whole thing and start over? Assuming I wanted to capture deep sky objects and moderate light polution.

At prime focus (i.e. without a focal reducer or Hyperstar-like system) getting pinpoint guiding with a secondary guidescope is tricky, but an OAG does wonders...starlight express makes the best in my opinion. Optically the C8 is still fine, you might want to re-collimate it, but that's a bit of an after thought. Calculating the backfocus for your optical train might be tricky. But once you have it set-up on a computerized mount (getting plate solving to work would probably also help, I can recommend Sequence Generator Pro) then you're good to go!
