The Celestron 8SE is based on an altaz mount. For long exposure video or photography (exp>30 sec), you would need a wedge to eliminate field rotation. The SE was not designed with a wedge in mind. Due to tripod stability issues, it is difficult to outfit it with a wedge, if you live South of latitude 60 (Anchorage, AK).
The alternative is to go with a camera that has a modern Super HAD II sensor. These sensors are much more sensitive and hence give good results with shorter exposures (30 sec or less). This eliminates the need for a wedge. The following cameras have Super HAD II sensors. Entry level: Mallincam Micro, AVS DSO, Samsung SCB-2000. More advanced: AVS MK-IV. Non-video: Lodestar x2.
To enjoy DSO's with an altaz mount you will need a focal reducer that gets you close to f/3, as one of the following: Meade 3.3 reducer/corrector, AVS Vario-reducer, Mallincam MFR-5.
On the software side you may consider AstoLive for the video cameras or LodestarLive for the Lodestar. Both of these have stacking algorithms that compensate for field rotation. Using them you can stack several shorter exposures. You can also control most cameras from these software packages. (At this point AstroLive cannot control the Mallincam Pro Jr and the Samsung SCB-2000.)
Hi Dom. I am new to video astronomy so have been reading as many posts here as possible. I have an opportunity to pick up a new scope for a significant big birthday next year and was looking at the Celestron Evolution 9.25 along with an Astro-video APU1 or Mallincam Jr. Pro. Given the Celestron Evolution is Fastar capable, does Fastar serve the same purpose as a focal reducer or would you still need one? Do these video cameras APU1 etc. mount directly to the Hyperstar lens which replaces the secondary or are they only meant to slide into the focal tube?
Thanks for your help!
