Re: [ap-ug] M27 with 110 refractor

Nice work Roland.

I noticed something in the image I've never noticed before in images of M27, and that's what seems to be a distinct jet coming from the central star at~4 o'clock , if that's indeed the central star.

Very nice!

Roland, do you have Raw 6200 files to show the stars to the edge of the chip? Thanks

Hello Astronuts,

The other day I had a clear night for testing in the observatory and asked for suggestions for what to image. Unfortunately i had some technical problems with the camera that was not resolved until late that night. I chose to image something bright and M27 happened to be overhead. So here is a crop of this little jewel:
I have been testing the 110 GTX Voyager scope with various flattener optics and comparing the results against bigger scopes. It's surprising how well it does against the bigger scopes under various seeing conditions.
