DSO 3 - M31 and NGC 884

We were blessed with a nice clear sky last night in Cork so I just had to go out and play.
Here are stacked/processed photos of Andromeda galaxy and the double cluster NGC 884 with
some photoshop voodoo applied.



OTA: WO 72mm Megrez w/ Moonlite Focuser & SkyWatcher FF & LPR Filter
Camera: Nikon D3100 14.2mp
Mount: HEQ5 Pro
Exposures: 10
Exposure: 45sec
ISO: 400



OTA: WO 72mm Megrez w/ Moonlite Focuser & SkyWatcher FF & LPR Filter
Camera: Nikon D3100 14.2mp
Mount: HEQ5 Pro
Exposures: 1
Exposure: 1min
ISO: 3200

These were all unguided using the HEQ5 Pro. Just some accurate polar alignment.

The SkyWatcher FF (which I got from Stephen at KTEC) made a huge difference while imaging with the 72mm Megrez, as you can see from this shot without the FF:

DSO 1 - First Imaging of the Orion Nebula

As I was dodging clouds here and there, I was only able to take four decent exposures but I was desperate to get my first bit of deep space imaging done. Here are the results:



OTA: 120mm Achromatic Refractor
Camera: Nikon D3100 14.2mp
Mount: CG-4 mount
Exposures: 4
Exposure: 20sec approx
ISO: 800


After consulting the forums, it's clear that I need to know light and dark frames very well. Whatever they are, they may help with my blooming stars, but I think a little more time focusing correctly will help too.

So there it is. First of many.
