M81 & M82 - First Go Using EOS CLS filter

[Roy Batty]

I wouldn't like to hazard a guess at the number of re-works this has gone through to get to this point . Don't get me wrong - using the CLS filter is a definate plus (no bright LP bulge in the centre now to deal with ), but it has meant that a lot of the previous processing ways I've fallen into don't work now. Even now I think it's still early days to learn how to get the best from my DSLR and this filter.

Anyway after much fretting, here's my first go

Cracking image Roy, excellent detail in the spiral arms, what sort of exposure did you give it?

Steve..

[blinky]

as some body else has said before, you get a green tinge to everything. Other than that it's a lovely image!

[cygnusx1]

how long and many exposures did you do?

looks really good, perhaps a bit longer for that final touch!

[zhgutas]

very nice! nice detail in that spiral!

All thanks for the comments.

Typical once I'd posted this last night and had a look at the result online I thought it could do with a bit of tidy up. (note to self - don't post stuff late at night as you're bound to change your mind in the morning ) So here's the re-work again...

Oh, BTW for those of you who asked it was 1min subs X 80 @ ISO1600 -unguided.

Thats really lovely. Nice and sharp and crisp. I have been experimenting with the EOS clip filter also, with varying results. It definetly helps to cut the red light from the cities that surround me, I haven't yet found the perfect way to get rid of the hues left by the filter, other than by de-saturating the image and trying to re-balance it.

But you should be proud of that image, I know I would be

Roy, That's a lovely image - M81 is a real stunner in that image!!

[RobH]

Great image with lots of detail and very noise-free Roy, going for lots of exposures has given real depth.

Cheers

Nice detail in there Roy, and nice 'tight' stars too.

Well done!!

I've been experimenting with the "Selective Color" tool in Photoshop CS3 - it seems quite good at taking out the unwanted hues mentioned by TJ & blinky above.

In the image below I've reduced the cyan percentage using this method, I think it appears to have "warmed up" M81 as a result - anyway grateful for any thoughts?

cheers
