Helix from ASIGN

Post by Barry »

I finally got a few more hours on the Helix. I kept taking 900 second subs each time I got a clear night. Some nights had very bad seeing, lots of humidity and orange sky-glow from the suburbs.

I had 54 subs to choose the best from and got a cumulative exposure of 5 hours as a result. The rest were rejects.

One of the big problems I have been having is my focus shifting when the telescope becomes vertical. I may have to come up with a solid backstop to attach to the tube, hook around behind the camera and have an incremental screw to fine tune the focus for zero shift as the aspect of the telescope heads for the zenith. More on that on my DIY pages when I get the site fixed up.

So here it is. I think I will leave this alone as I have been itching to try other targets.

Blessings,

Baz.
