M27 The Dumbbell Nebula – revisited

I recently decided to revisit the beautiful planetary nebula that is M27. The plan was to start from scratch, collect several hours of exposure and create a very deep image. However the fates conspired against me – for once my weather forecasting info was inaccurate and heavy cloud came in after only 30 minutes of exposure. However there is little point in arguing with the weather, so I gladly took what I had and combined it with my previous 17 minutes of data from late July.

I’m quite pleased with the outcome but would still like to do a several hour exposure some time.

As usual, here’s my Messier Infocard for the object.

    Nice – what a difference long exposure times make. Hope you get some good viewing so you can get even more detail.

    that is an amazing result! you images taken with that C6 is darn perfect! I love them.

    In fact, how handy is that C6? I mean, how is it’s performance?

    I have William Optics Zenithstar 80mm ED semi-apochromat refractor, although its quite fast, the field of view is too large, and the focal length is too short for my objects of interest.

    Thanks for the encouragement there.

    Yes I think Celestron have made a great little scope with their 6inch SCT. Sometimes I think that a bit more focal length would be good but I don’t think I’d swap it, in truth I’d want a C9.25 as well. I haven’t done any scientific measurements on it but my gut feel is that its pretty good for the money.

    All that said I’m very much in love with the Canon lenses too – the L series APO is stunning but so it should be for considerably more outlay than the 6″ SCT !!!

    I’ve heard really good things about the Williams Optics ED80, it should be really great for many nebulous objects. What sort of objects interest you Tuguldor?

    hey thanks for the response. I am mainly interested for some planetary NGC nebulaes. WO 80ED performs perfect for wide field images, but it is not sufficient enough for those tiny diamonds.

    I am also doing some “research” on Orion 127mm Mak-Cass scope. Will decide soon whether C6 or Apex.
