I didn’t realize until tonight that I had yet to try afocal astrophotography with my iPhone, which I got late last year. This was a clear, cool-bordering-on-cold night, with the Waning Moon at a good evening location, so it seemed like the perfect opportunity to try it out.
My prior afocal attempts were with my previous Android Samsung phones. Those were a little easier to place in the telescope smartphone mount because their cameras were centered on the phone, whereas the iPhone’s camera are off to the side.
I used my homemade Dobsonian with a 2″ eyepiece, my best one. Once I focused the telescope and aligned the smartphone mount properly on all fronts, it was very easy to attach the mount onto the eyepiece. I noticed immediately that there was no vignetting, which seemed, if my memory recalls, to have been much more of a nuisance with 1.25″ eyepieces.
I made a few minor touchups in PaintShop Pro and AfterShot Pro.
