M33

[martin_h]

After much faffing about in PS this is as good as I can get this (keeping in mind I havn't a clue what I'm doing)

So....

14x 10 mins Stacked with darks and flats in DSS

Pushed, pulled and generaly bullied in CS3

Taken with - Evostar 100ED and QHY8 in Nebulosity 2

Guided with - ST80 and PHD on a HEQ5 pro

Nice Martin, M33 is a difficult one! Image has a purple/magenta cast on my monitor- perhaps a little too much red channel. Did you use a reducer on the ED100?

For someone who claims not to have a clue what they are doing that is a blindingly good result

Well that's pretty good and, as for Photoshop thuggery, we all do it! Well, most of us...

I suspect you have a bad flat though, somwhere, becuase of that slightly dark patch above and just right of the nucleus.

There is a lot to admire in this image - good signal, dynamic range, detail. Nice one.

Ive just looked at it on a different monitor and you're right there is a magenta cast-grrrrr.

And yes I used the dedicated reducer for the scope.

I've just checked through the flats are they are ok....but the patch is on the original light frames, the anoying thing is tho, I did the flats right after the lights for a new master set, so I don't know why the flat didnt pick it up...another thing to sort out!

[ollypenrice]

It never ends! Lifting the green might also kill the magenta. The image is worth some effort.

Stick at it.
