Description

after almost a year, I'm still trying to figure out this ASI178. One of the biggest issues is getting the back focus on my Nikon lens adapter set right; if you miss that, then none of the colors come to focus at the same point. I've got it dialed in a little better now, but it's very irritating that none of the numbers on the web seem to be entirely accurate. I'm going to shoot some calibration frames in the morning and try to clean this up a little, but it looks better than my last attempt already.
