Jupiter with nice NEB turbulence
Hello everyone! I just joined the site and am excited to see such an amazing group of astronomers sharing thoughts and images.
I'm based in Wellington, New Zealand, which everyone knows for its windy weather. That means most of the time the seeing is pretty poor - whether it be from atmospheric turbulence or from telescope tube vibrations! However when it's still, the seeing CAN be very good.
We had such a night on September 21. There was a bit of wind around and the image of Jupiter was leaping all over the frame, so it's likely not the best resulting capture I can ever expect. I use a Skywatcher 12" Auto (alt-az tracking) Dobsonian, with Orion filter wheel/filters, Orion motor focuser, and a DMK21 USB camera. With a Shorty Plus barlow and a flip mirror in the path, I get an effective f/25 - not as long as I'd like really, but given the slop in tracking I'd find it hard to keep a larger image in the FOV.
I wanted to share the result of one of the AVI runs, which I think really shows the maelstrom happening in the NEB. I'm pretty happy about the detail captured given this is "just" a Dob and it was a bit windy.
Comments and suggestions are very welcome!
