    Default M44, the Beehive



    Tried something a little different last night.

    Instead of doing my usual 4 min subs, I thought I would try to do 2 min subs and just do plenty of them to see if it would help some with my poor guiding results so I did 60 - 120 sec subs for a total of 2 hours. I figured M44 is fairly bright so I could get away with shorter subs. Well as far as visuals, the shorter subs worked for this object but you can still see a lot of coma around the edges. Not sure if this is a result of poor guiding or just the design of my 6" Newtonian.

    The Beehive is one of my favorite clusters. I think you did a nice job capturing it. The bright stars at the center of the image are what one will be looking at, so the small amount of coma in the stars around the periphery of the image isn't all that noticeable. A coma corrector would definitely be a useful purchase if your scope has a 2" focuser and you wish to continue using it for astrophotography.

    Hi Scott,

    Man, you are fortunate to be able to get 4 minute subs anytime. You must have nice skies.

    Nice bright stars in your beehive image. I like it very much! Good job! I hope that you get your guiding issues worked out soon.

    Thanks,
    Jim

    No question whatsoever that you have a bit of coma. Your guiding looks excellent, if you ask me.

    You can always tell the difference between problems with coma and problems with guiding.

    Guiding errors effect ALL stars the same and in the same direction. Coma is noticeable at the edges but NOT in the center.

    I am going to a star party in a couple weeks and I think after that, I am sending my mount back to Celestron so they can tighten everything up for me. I have an idea of how to do it myself but with my mount being past its warranty date, it would be best just to let them take care of it instead of me possibly screwing something else up on it

    Very pretty image!

    You don't have a guiding issue. The coma is 100% optical, and a coma corrector will fix it. It is pretty much a requirement for a fast Newt.

    I remembered this morning that I forgot to run SCNR process on my original image and I created a luminance mask to see if I could bring out the blues and reds better. I like the way this one looked better so I replaced the image on my flick page with that one. Here is the link to the new image.
