Ken my advice is dont get the "Andrews" 2 inchers.
I got the 26mm and was very dissapointed by its performance at f5. It was then that I learned what they meant by "seagulls".
They are a 3 element Kellner basically. It may work fine in an f10 sct , but totally unsuitable at f5.
For $100 the 30mm superview is your best bet and will equal or better anything this side of a 27mm panoptic. The 30mm will give a 6mm exit pupil at f5 which is about as big as you want to go.
I hope to do some galaxy hunting myself before the moon returns. This one over here on the left i want to take another look at
