IC2944 - Bok Globules - Ha/Oiii

[JohnH]

Here is my first attempt at this target - due to my small sensor size I have had to select only a small portion of this target so I chose to go for the bok globules - this leaves my composition unbalanced but I am quite happy with the detail for a fist go.

The image is synthetic colour Ha - Oiii with (40*4 mins of each) - there was virtually no nebulosity visible in the Oiii frame (perhaps longer subs are inorder?) and I have not yet got my NB processing to the point where I can preserve star colours.

Hi John
It looks like the black point is really clipped?
And like you said, the stars have lost their colour.

It's a nice start though!

What camera are you using john

The globules really stand out well in this image.
Thanks for posting.

Trevor, the image was taken with an Opticstar 145m and I used astronomic filters, the camera had the Sony ICX285AL chip which is quite good in terms of sensitivity - but a little small for the 127mm F7.5 refractor I use it with - a better idea of what the camera can do is shown by this image...

Mike, I did have to stretch quite a bit but did not clip the blacks - I did notice the histogram was very steep though - I think because my subs were too short...
