Ghost of Jupiter & Centaurus A, C8 F10.

I imaged NGC 3242 (Ghost of Jupiter) Planetary Nebula while waiting for Centaurus A Galaxy to rise in Alt.
NGC3242:
C8 @F10; Canon 450D (non mod); 4 x 5 min ISO400; 5 x 3.5 min ISO400;
10 x darks; No flats;G11, tracked with WO 70ED & QHY5.
Stacked in DSS, curves/levels in CS2.

I imaged this while waiting for another target to come into a better view. I was surprised by the small image scale. It is really a very small target so this is an enlarged crop.

Outstanding colour in the object. It is so unusual.

Again I am very surprised at the ability of the C8 scope. To think I nearly gave up on this scope. This is a keeper.


Centaurus A galaxy (NGC 5128) is a much imaged galaxy. Yet I was again surprised but the image scale of the C8.
NGC5128:
C8 @F10; Canon 450D (non mod); 5 x 4 min ISO400;5 x 5 min ISO400; 5 X darks (battery ran out); No flats;
G11, tracked with WO 70ED & QHY5.
Stacked in DSS, curves/levels in CS2.

This was shaping up to be a good astro-photo but the dreaded clouds rolled in & my battery went flat doing dark frames. I'm building a battery PSU, to fix this, but are still waiting for parts.

I need to experiment with different ISO setting some more on this, and, maybe next time the clouds will stay away so I can get in more subs.
