Moving the mirror up the tube, by replacing the mirror cell screws with longer ones and using threaded spacers, is also an option. It's reversible. No hacksaw required, just a bit of nerve to dismantle the mirror cell.

Got a bit more data this morning so total of 18x300. Getting tired of processing this one now and I think I've settled on this version. Used the arcsin stretch in PI which has always produced pink star cores but a slight adjustment in curves brings them back pretty well. The colour comes out a lot more natural.

Notice the double difraction spikes? That shows the focus is off.

True. But that then makes darks necessary? I couldn't be bothering with all that nonsense! For the small outlay to get the mount controlled by pc so dithering is possible/easy it's well worth it in time/hassle saved.

Not that I'm aware of. I've always used eqmod. Perhaps someone else might know.
