IC1318 Region in Ha

Recommended Posts

Took this a few nights ago in Ha and hoping to add other channels to it when the clouds/rain move on:) Not sure I've got the levels/curves right at the moment though.

Taken with an Atik383 camera, Baader Ha filter (1.25") and Canon 200mm prime lens at f2.8. Exposure was 8*15min, processed in Astro Art 5.

Thanks for looking,

Rich.

Nicely detailed with lots of faint whispy nebs that look like raging storm clouds. The Crescent Nebula stands out sharply. Amazing imaging here. Very fine work.

Thanks Jim, hopefully we won't have to wait too long here for some clear skies again...

Thats a corker! The stars really do look 3D in front of the nebula..

How did you attach the 383 and Ha filter?

That's wonderful - superb detail and surprisingly at F2.8 (fully open). What a great piece of sky this is.

Thanks Kevin, Guy and Steve. I've not tried the lens stopped down as I wanted to avoid the diffraction spikes you get with that, I should try it though to see what difference it makes to the star sizes (I did quite a bit of star reduction to try and make the nebula show more with this, I'd rather have just a handfull of stars left!).

The camera is attached to the lens using an adapter from 'Mogg Adapters'. I use the Starlight (T)-EOS adapter, I couldn't achieve focus with the initially supplied ATIK-EOS adapter. There is the slight issue that the T-thread on the adapter is deeper than the T-thread on the 383, which is quite shallow... the interface I have seems good though to me.

I have recently received the 1.25" filter holder that fits inside the adapter but not tried it yet, still using a DIY effort that I made while I waited for the holder to arrive.

Thanks,

Rich.

Nice to see images done with 'standard' camera lenses and CCD's - it's a great widefield result.

It always amazes me that you can point a camera lens at the sky with a 6 degree diagonal FOV and have nearly the whole image full of gas. Before I started long exposure astrophotography I never realised just how big these objects can be.

Cheers,

Rich.

Wow... What a beautiful image! As Guy noted, it's almost 3 dimensional... Having recently filled the frame with the crescent nebula, this REALLY puts it into context!
