Bubble nebula and M52

[dark star]

i am quite pleased with this, you can just see the bubble! As usual more time needed!

Around 12 x 300 seconds and 3 x 600 seconds exposures, modified canon 450d, ISO 800, Astronomik CLS clip filter, Skywatcher Equinox 80ed refractor. Finder guider and DMK41 camera for guiding with PHD . Photos taken using APT.  Darks, flats and bias frames. Stacked in DSS and processed in Photoshop.

The stars for some reason look a lot better than when using my Orion Optics UK 250mm F4.8 reflector with a coma corrector, maybe my collimation was out. Guiding also seems better. Next time I will experiment with longer subs. Cloud stopped me trying this time. Any comments gratefully received.

Thats a nice capture. To bad you'll have to crop it to get rid of the eggy stars. At least they dont look bad around the Bubble. You just need a flattener to fix that.

Very nice to see both objects in frame , makes for a much better picture in my humble opinion ... 

Same with the "Fireworks galaxy" ,  NGC 6946 , always looks nicer teamed up with the open cluster NGC 6939 I think .

I hadn't noticed the stars at the edges until it was pointed out. Does anyone have any comments regarding the Skywatcher field flattener vs the Televue flattener/reducer? The Skywatcher is considerably cheaper! Plus I don't really want a reducer. I am thinking of trying my 150mm Mak sometimes so I can zoom in, I have a reducer that takes it down to around f/8.

When it comes to the Equinox, I have one, the common grey/black one does not work with it. The TV 2008 ff/r does work with it. How ever it is a bit more pricey. There are one or two ther but they slip my mind atm. Sorry. You could get just the ff if you dont want to pay for a ff/r.

Nice shot of a faint target as Steve said nice to see both objects in the frame.
