Do any of you image a star to help you estimate the seeing? I was just looking at the animations on Damian Peach's site to try and estimate what I think I remember from this night and now I think I will start doing this to try and train myself.

Anyway, I'm going to say that this was at least a 6 on the Pickering scale. I'm really excited to get another chance and try and up my fps a bit. This particular video was at 59FPS according to the FC log and this is a 50% stack. I have quite a few videos to go through, but am going to pace myself, as it looks like a 10 day'er at least until we'll get a clear night again. This was the last run of the night; 02:05:10UT.

Steve,

Thats a really nice detailed Jupiter! Yup a star at high power, if its a really tight pinpoint is a good indication of seeing. I use the Galilean moons too, Ganymede on average is about 1.6 arcseconds, Io is just under 1. So if they appear to be distinct little globes then your seeing is very good! Also the cassini division on Saturn is about 1-2 arcseconds too, so just figure the %age of time you can clearly see it. So close double stars are also a good way to estimate the seeing, but none come to mind right now :)

cheers

Mike

Thanks Freddy, Trevor & all!

@Sam: I do use a TV 2.5x Powermate and I drizzled (I think that's what you meant to say) this 1.5x in AS!2, processed and then downsampled it a bit to post here. It looked a little soft otherwise.

@Mike: The moons! Good idea, I can practice on some older videos...one for poor I think and the other much better!

@Magnus: Well, it's a C8 and it's from that era. I can't positively identify it though. I got it from a non-astronomer, not the original owner with no paperwork. I'm very pleased with it though! :)
