For a first go, that's an excellent image Greg.
What software did you use to stack the frames?
Graeme
Thanks! I used Autostakkert, then sent the stack to registax and adjusted the waveletts, saved as TIFF for four 5800+ frame videos (2 minutes total integration time as each video was 30 seconds long). Yes quick math shows 195+ frames per second. Then finally, I took the four tiff files and loaded them into Winjupos to de-rotate with final minor color adjustments in Photoshop.
The soft focus is either due to the "seeing" conditions (85% humidity in the middle of winter) or my refusal to fiddle with and check collimation on my 8SE
OTA each and every time I focus. I suspect collimation is a red herring for the 8SE because I cannot lock my main mirror, so any adjustment in focus moves the mirror and may cause the collimation to go out. I heard the EdgeHD can lock the mirror. Does anyone know if this is true for the 8" Edge HD? I heard the 9.25" EdgeHD can lock it's mirror as can the larger EdgeHD scopes. If the 8" Edge HD will lock the mirror, I'll probably go that route.
I tried googling to search to see if the 8" EdgeHD can look the mirror but the results were inconclusive.
