Seagull Nebula IC 2177 300mm lens unfiltered

[tornado33]

Hi
last night I went for the Seagull Nebula IC 2177, with no nebula filter to see what I got. A long session for an f2.8 system, 17x5 mins ISO200, with just a uv/ir filter. Canon 300 mm f2.8 flourite lens from Bert. Cool dry conditions, clear skies but a little hazy, could only just see the LMC. Most of the Seagull is fainter than the Horsehead, so its very faint indeed, would make a near impossible visual target methinks.

hi Scott, nice result!

Are you processing differently now, Scott? Your latest images are a wealth of star colour, more so than I seem to remember from older images.

I love it!

he is now using secret herbs and spices - oh and iso 200

Looks great Scott with the higher dynamic range. Any chance of a higher res version?

Thanks all
Yes ISO200 is the go for unfiltered images as any higher and theres too much skyglow, also star colours are better as the pixels can fill more.
yes I now add a bit more saturation, that improves the star colours

Heres a full sized version (over 2mb)

A little bit of haloes round the bright blue stars but remember this is with a modded camera on a lens open to f2.8, also could be some interaction with the UV/IR filter that being an inteference type filter isnt really intended to operate at such fast F ratios. Note the sharp round faint stars, I think I nailed focus pretty good Amazing they can make lenses that hold quality out to the edges at these f ratios.

Very nice colors indeed !!

Hi Scott, I have had a look at both your sea gull images, and they are both great captures, however IMHO i reckon the 300mm lens one, although much fainter is the better of the two.

The colours seem more pleasing, as the second one looks very saturated, please don't get me wrong, both are excellent for such a faint and distant object.

Thanks.
Yes the 300mm lens at f2.8 is really great for catching such faint objects. Nebula filters bring more detail out but do seem to make it more "monochromatic", all red and little other colouring.
Ive just compared both and note that the 300mm lens reaches the same stellar mag. limit unfiltered as the filtered 6 inch shot.
