Re: M2 Globular Cluster reimaged

Pete

Thanks.... I do use a focal reducer so my actual FL is about 1960... way less than your 14 inch. I also do run a sharpening and star size reduction tool in Pixinsight which helps a little.

Someday I will start imaging the 11 inch SCT without the focal reducer and see what I get.

M2 Globular Cluster reimaged

M2 is a fantastic globular cluster. Since it is situated in Aquarius, it is fairly low in the night sky, at least for me. I have trees to the South of my observatory that impact how low I can observe/image A couple of years ago I imaged M2 with my 5 inch refractor. I decided to give it another try w...

Re: Canon 450D NGC7000 Ha

Frank I know the entire area has some red nebulosity, so it is difficult to process. You are doing a great job. In order to get the stars back to their natural color, without impacting the nebula, I would recommend a process to remove the stars from the nebula. That way you can work on the stars i.e...

Re: NGC 6946 - The Fireworks Galaxy

Pete Great job of capturing the Fireworks galaxy. Stars are really pin-point. I really like your image. Framing the galaxy the the open cluster (I believe it is NGC 6939) really adds to the depth of the image. I don't understand why you had to throw out images with satellite trails. The stacking pro...

Sharpless 101 (Sh2-101) Emission Nebula

Interesting night last night. I decided to try and image the faint nebula Sh2-101. It is in Cygnus so it is well positioned to allow long exposures. I have been 'battling' with observatory computer occasionally 'hanging-up' forcing a shutdown and restart. I did some on-line searches and found severa...

Re: UMass-D Imaging First Light

Mark

Great news ....

The Ring Nebula looks really good at 4000mm .... stars are crisper than I would expect for an unguided image with F/L of 4000.

Great progress

Re: M56 Globular Cluster

Thanks for all of your responses.... and really good questions. First of all, I agree with Pete that usually globular clusters 'only' require a couple of hours of integration time. I imaged M56 2 years ago and had 100 two minute subs. I was not entirely satisfied with the result. Or rather, I though...

M56 Globular Cluster

The weatherman fooled me again last night. According to cleardarkskies, the night was suppose to be party cloudy, clearing after midnight. It turned out to be clear all night. Based on the (flawed) weather forecast, I decided to re-image the globular cluster M56. I imaged it a few years ago but was ...

Re: Sh2-112 reprocessed

Pete

Thanks, I really appreciate your comment.

I find searching for, setting up, imaging and image processing are all rewarding efforts (although sometimes they can be frustrating).
