Well, I'm continuing on my DPAC journey and was able to run some tests on my Stellarvue SVR80ST2. Aligning the focuser on this telescope was very finicky. There is not much room where the FT draw tube passes through the collered flange. I did get it really really close though. One thing I've noticed is how touchy alignment is on all parts of the telescope. I can see movement from just the normal brass compression rings slightly moving the final position of whatever you are using. It's a wonder that anything stays 100% aligned at all times, lol.
I'm still working on my image taking, I'm having a bit of trouble with the LED 'shine' blowing out areas of the image. It's tricky to get the LED's just bright enough to illuminate everything and not too bright as to blow out the lines. You can see what I mean if you look at the outside focus (white) and see the bright spot, then compare to the outside focus (red) and the lines are blown out.
I've also switched to a lower LPI ronchi as I try my @Focus pictures. If anyone can tell me how to position the ronchi lines when doing @focus images that would be awesome. (ie. Do you focus in on a line, or the edge of a line, or the space between the lines?) I ended up focusing so that some of the line was visible otherwise there was no definition in the image at all. Not sure what's best here..
I also spent some time making this 'Results' sheet. It's an excel file and I can share it with anyone that wants it, just DM me.
