Re: Lunt 50mm question

I had the same problem when I used a LUNT50 belonging to a friend. You have to use a low profile 1 1/4" adapter (see the second and third photo) to reach focus. Changing the focuser for a FT also helps

Re: 19th and 21st April lots of testing

Great images Alexandra, love the HR WL. Ca-K imaging is always tricky. I could never go over a X2 Barlow with my LUNT152 Ca-K module

Re: Today's SUN (20190419) | Coronado SM comparison images

I agree Mark

Definitely the SM90II does not like short focal ratios. It works better at F/10

The SM040II works fine and I have two Pre-Meade SM40. I will have to compare the two side-by-side

I also have two SM60 (Pre-Meade). Only one is a good performer (for imaging)
