First clear night in forever…

Tonight was pretty clear with moderate seeing conditions. I decided to get out and try out some autoguiding. This evening I used both PHD Guiding and Envisage’s built-in guiding. PHD is better by far. I have yet to see if I can guide with PHD and capture with Envisage (with different cameras) at the same time. I hope so.

Anyway, the M27-Dumbbell Nebula above is from my Envisage guiding. It allowed me to take 1 minute sub-images to build this one. I even had a couple successful 2 minute subs, but they weren’t reliable enough to stack on so I just stuck with 1 minute. The result is my best M27 shot yet – lots more detail on the filaments that make up this beautiful planetary nebula. I’m excited about being able to start using what I’ve learned about drift alignment along with autoguiding to start creating some extremely long duration images. If I can ever get to 10 minute subs, I will have really arrived and I don’t think I’m that far away… Note that if you zoom in (click on the image to be able to see other sizes) there’s a lot more detail than in previous versions.

  1. Hi!

    Nice shot of M27 there. I worked on that one last night and had a little “encounter” ( http://asterythms.net/blog/?p=28 ). I noticed you use Envisage. In fact, I’m fiddling around with it lately and I have yet to understand why it fails that often. But the good side is, that I learn an awful lot about my telescope setup. That’s surely good.

    Back to your blog: you have a number of really nice photos here and I will surely come back šŸ™‚

    Bye

    Frank
