The Dumbbell Nebula 30 single second exposure

[Ultrapenguin]

Hi all, thought I would post the latest image from my new observatory. Single 30 second exposure iso 6400 on a SW150pl with tracking motors but no guiding.

I love this kind of wide field imaging. Looks brilliant.......BANG!

That is great. Collect 200 of those, stack them together, add a few darks and flats, and you'd have a very impressive image.

Great work.

Good effort. I recently was in between CCD camera's, so I thought I would hook up my Canon 5D MkIII to my OO 12 inch ODK. I set the ISO to 400 and exposed for one minute. I was surprised by the sensitivity of current camera's for astro imaging!

Ccd, you must also have pretty dark skies! Nice capture.

James, I live 2 miles north of Royston in Hertfordshire, so not as bad as some, but I am looking forward to the real dark skies of Kelling Heath next week

I also did  little processing to remove the background gradients

That's a cracker of an image ccd, I am also very surprised by the results modern DSLR's can achieve. To give some hope for others, although my image is no where near as nice as yours it was taken from a very light polluted garden with a 6 inch scope and a canon 1100d  I purchased from ebay for £125. So you can get half decent images with basic equipment especially if you use a modern DSLR. I still really like your image though ccd and I am dreaming about what kind of visual views you must get through that 12 inch scope!

The scope is really developed for AP, so tbh, I haven't really looked through it other than to collimate. Because I put a feathertouch focuser on it, it won't reach focus with a diagonal and 2 inch EP...

But you are right about DSLR's today, the noise is so much less than a few years ago. The only problem is that they are not very red sensitive..

I knew I had a single sub of M27 somewhere. 60 seconds with Canon 6D on a 180mm Mak-Cassegrain at ISO 25600. My polar alignment is always awful and this shows at a focal length of 2700mm.

This is my attempt at the same target, with an unmoddified canon 1000D, 7 x 3 min exposures and the same in darks

Hope,you like

That really is a cracker Olly, you can begin to see filament structure in your image very impressive.

Thanks very much for the kind words

I found that a lower ISO had better results where I live because of LP, I think if I remember I used 800, I did try 1600 but got too washed out too quickly

Since I did that one I have had my camera modded so would like to return and do that one again, and compare the results
