Fridays Moon and a Jason

#1

Post by Thefatkitty »


Hi all, hope you've had a good day :D

I thought I'd post this simply because I'm rather pleased with how this worked. I have an old 80mm f/15 Jason I bought for $80; a dollar a millimeter. It came with a .965 diagonal and small focuser knobs. The focuser itself is rock solid, as a lot of these older R&P's were/are. Too bad the attached parts are crap....

It turns out the tube on the focuser that the .965 diagonal holder screws into has the exact same OD as a regular 1.25" eyepiece, etc. How convenient. So I used some 1.5mm plastic, duct tape, and two hose clamps to make a bracket. One problem solved.

I can't get a 10:1 focuser for this, at least not a GSO; the ID of the tube is an odd size it seems. So I decided to go the "jar lid" route, which will at least give me some leverage :D I decided to put the same size jar lid on both sides as well. I'm glad I did, it's so much easier to focus holding onto both as well as them being bigger.

I've had a long week, and getting in last night, the sky was lousy as it had snowed most of the day. However, I was forecasted some clear skies at 9PM. Well, it turned into more like 9:45, and there was still a lot of humidity and some high thins floating about. I was surprised, as the temperature was 21F (-6C). I had set the scope out on the mount at 9:00, so it was certainly cooled. I know fracs are supposedly "ready to go" at a moments notice, but I've found that a temperature drop from room temperature to something like 40F (4C) or lower requires some cooling time to have a steady view.

By 10PM the sky looked to be as good as it was going to get, and it turned out I was right. I had connected my T3/1100D into the Jason about 20 minutes before, so I took 40 shots at ISO 1600 and 1/250, 1/320, and 1/500th respectively. The ones at 1/320th exposure time were the best of the lot. It's funny, at the same ISO with my C80-HD at f/11.4, I'd be using 1/1000th exposure... By 10:45 the thins were starting to thicken, so I gave up on anything visual, and in I went.

These are the pics. I know the Moon shot isn't the best, but neither were my sky conditions. Or even the scope I'm using :lol: Though I did notice the CA "ring" I usually get with my C80 is almost nonexistent... :D

Awesome! That's a really nice lunar capture with the Jason, Mark! Sweet!

I have a co-worker named Jason. He was regaling me with a tale of one Christmas morning when he was young. His older brother was gifted with a telescope for Christmas. So in pops my co-worker see this nice shiny new telescope standing beside the Christmas tree. He immediately thought it was his because it had his name embossed on the side. :lol:

Excellent capture, ol' buddy!
