Late night & no time to cool down the CPC1100 so had to make do with the FLT 110. RGB videos still being processed but here's an interesting & different shot:
Quite amazing to get Hyperion with a 1/4 sec exposure and only 4.3" aperture. There are several mag 13 & mag 14 field stars in the shot too. Mimas and Enceladus escaped though being embedded in the glare from the planet but otherwise this is a complete set of the 8 main satellites.
The dark haloes are sharpening artifacts (shove the boat out & gather up the light from the wee specks) and the dark line running through the planet is a "blooming artifact" of the type you can get from a CCD when bits of the image are grossly overexposed despite the action of the anti-blooming gate. Of course the gamma has been forced ridiculuously high too.
Edit: composite added. Proves Saturn can be shot reasonably convincingly with a small scope, despite low altitude and swimming pool seeing.
