M31 (what difference a dark sky makes)

Recommended Posts

I've found a new dark sky site only 20 minutes drive away, so here is

my first test shot of the Andromeda galaxy taken with a 200mm lens

on my unmodded 550D on the Astrotrac, only 37.5 minutes (15 x 150 sec)

F3.5 @ 1600 iso, no filters, no darks, no flats, I just let the photoshop

raw converter take out all the hot pixels.

Wow - that is stunning!

Just got to try that. As it happens I have a 200mm lens around here somewhere!

Alot of detail in this image.

I'd be interested to know how this image was processed ie. How were the subs stacked and what processes were applied in Adobe? Also, which 200mm lense was used?

Regards

John

Absolutely stunning!!

One question though. Why do the bright stars have 8 diffraction spikes? Did it come out like that or did you add them?

Thanks for the comments everyone, in answer to your question John

the individual frames are stacked in photoshop and opacity adjusted.

I then used multiple curve layers, selective colour layers to darken

the blacks, reduced opacity minimum filter to reduce star sizes and

a little bit of surface blur to smooth things out (this was only 15

frames @ 1600 iso). It can take a long time and a lot of fiddling to

get it right but I enjoy it, it's almost like being back in the darkroom.

That is just an amazing image.... and so little exposure too... :)

I think these new Canons are top dog.... I need one :)

Well done, youve done a brilliant job.

Sorry to bump an old thread, but oh boy it deserves bumping.

Been looking at some of your images Mel. Absolutely stunning, each and every one!
