Great images, I particularly like NGC6559.

Unfortunately a single scope is not ideal for all images so getting
high resolution out of a 5 inch APO for galaxies will be challenging
although your NGC253 is very good.

One approach would be to use a high end barlow to get more F ratio like
Marcus has been doing with his TOA150.

Perhaps an AP Barcon or a 2X Powermate or a Tak TOA 1.6X extender.

Greg.
