M27 Dumbbell Nebula

At the inaugural meeting of the RAG Astrophotography Group (RAGAG) we were challenged to take a photo of M27.  Here is my attempt.  I’ve taken pics of solar system objects over the years, but I think this is my first one of a deep sky object – the first reasonably successful one anyway.  These are JPEGS, of course.  I have the Raw (Canon) files too, but have little idea what to do with them, as yet.

I have a Google Photos album where I’ve uploaded various astro pics this year.  This link https://photos.app.goo.gl/dbWpiRUhB5S3Qzmh9 should allow you to view it.

  1. Thanks all, for the comments and encouragement! This really is the first baby steps for me.

    I took pictures of the three alignment stars and then of Albireo and also Alcor and Mizar, to check I had the best focus I could manage. This was all done at the camera (Canon EOS 700D) as I don’t fancy messing around with a laptop in the middle of the night just yet. It’s good enough for me at present.

    I’ve downloaded the Canon codec, Neil, and will be paying attention at the next RAGAG meeting to see what to do next. I did cover the telescope and take a dark of similar exposure time, because I’ve heard they can be useful. Then the next few photos were wasted because I forgot to remove the cover … again, lots to learn!

    These images are JPEGS, one of 25 secs and one of 30. After experimenting with different settings, I decided that ISO1600 gave the best results, so I’ll stick with that for now.

    You’re comment made me smile Andy! I’ve had this telescope (a Meade 8″ LX10 SCT) since 2000 and the camera for four or five years. I’ve collected lots of pics in that time, but never done anything with them. My Google photos page has some examples (see link above for this year’s collection). I have albums from earlier, but may be too embarrassed to share them … I really am just starting out in astrophotography and it’s seeing what others do – apparently with great ease – that encourages me to try harder.

    Thanks again for the encouragement. 🙂

  2. Great stuff Derry!
    When I see how fast other people like yourself and Jim are doing this stuff – like duck to water(!), I realise just how slow I have been to get to grips with it!
    Thanks for sharing and please keep them coming.
    What gear did you use and how many frames, length of subs, what software did you use to stack and process?
    Andy

  3. Congratulations on bagging 2 DSOs! Looks like focus is good and I can definitely see colours in Albireo and the Dumbbell shape.

    In the next meeting we agreed to look at stacking and calibration so that should help you with those RAW files.
