Try and use a bathinos mask if you have one.
I too had the same problem and the bubbles went once good focus was achieved.

Thank you for your thoughts on it Paul.
I didn't think it was focus because none of the subs have stars as big as what they turn into after stacking. It looked like they were expanded into bubbles or donuts during the stacking process. But I guess if you had the same problem then it must be focus. I've just been focusing using magnified live view on the DSLR (getting the diffraction spikes around a bright star as clear as possible) so yes it may be slightly out. I'll investigate one of those masks.
Cheers

Untick the boxes, then try again.

Thank you for the advice jjjnettie
I'll try stacking them again this afternoon (unless the weather finally clears up, inwhich case i'll be setting up the scope) with those settings off. I can't remember what settings I used. I really should keep a log of what I do use for future reference. Rookie mistake. I'll let you know if it makes any difference.
Thanks again.
