Celestron NexStar 4SE + 2x barlow, DMK41. Best 10% of 1000+ frames. Wish I had a colour sensor about now...
Processing: Pre-process in PIPP, stack in AS!2, wavelets in Registax 5, finish off in Photoshop Elements.

I had to look it up, but the blob at around 11 o'clock position is Ganymede, and the speck to the left is Io.

Just wondering, is it supposed to come out blurred like that? I'm assuming it's common as it's really far away and it might be hard to get it really sharp like the shot of the moon you posted earlier, but I really can't tell for sure.

Unlike the moon, it appears quite tiny, so you need massive focal length. For a given physical aperture, that means high f numbers and diffraction softening. Not only that, the air is very wobbly. This is actually sharpened a fair bit, but I didn't feel like applying more as the noise was getting rather bad.

Yeah, I kind of expected that, but I wasn't entirely sure why it wasn't too sharp. Anyways, thanks for the reply :)
