Another blackeye - doh! was created by dmcdona
Folks - M64 again, this time through the C8.
Details:
Object M64 (Blackeye galaxy)
Date/time 09/05/05 23:12 UTC
Exposure 30 sec
Image no. 12
Imager DSI
Mount AP1200
Scope C8 SCT, F6.3 reducer
I've a long way to go as regards processing - there's still significant 'graininess' in the image. I suspect that this has to do with camera settings (gain and offset plus contrast) which I have yet to master. If anyone has any tips or tricks, I'm all ears...
I've also to master the AP1200. I haven't yet calibrated the PEM (periodic error management) and I've still to use SmartGuide - an inbuilt logic that corrects errors due to poor polar alignment ( ) and a non-orthoginal optical axis. Thank goodness for this spell of clear skies!
Cheers
Dave McD

Astronomers do it with the lights off.

great shot Dave. I'm certain that Registax would sort it out for you with a little tweeking.
