For those who wish to film through their eyepiece I have found the following lower cost solution. Phone Skope makers a phone case and adapter that will fit around your eyepiece. It’s similar to other options out there but much cheaper. I ordered a custom 42mm adapter for my pvs14 eyepiece and IR Hunter. It fits snug but not too tight at all. The film through my iPhone is so far excellent once you turn down the exposure a bit. The only negative I have encountered is the weight of the phone will turn the eyepiece if you aren’t careful. In all it’s less than $100 with a custom adapter (universal ones are available) and it works. Here are pics.
