Hi all,

I borrowed a debayered Canon 350D DLSR for Alistair (Alistairsam) and tried it last Tuesday night on the M8-M20 region is Ha with a 165mm lens at F2.8. Image is 60 minutes as 6 x 10min subs guided.

Alistair removed the bayer mask from this camera himself. I was impressed by how well it worked and I thought I would share.

Best regards,

Mark

Looks seriously posterized and flat to me....

This region is 'oft imaged e.g. here (http://www.atscope.com.au/BRO/gallery257.html)

I suspect the, sorry....not great result you posted...... is due too much .jpg compression rather than the de-bayered camera.

Do you have a less compressed version?

nebulosity.

G'day Mark,

Great to see the mono 350d getting some use :thumbsup:

I'm yet to do some wide fields with mine.

Cheers
Jo

Thanks Jo, hope you get to use yours soon.

Thank you Peter for your comments. After a few minutes thought I agreed with you. It was not all a jpeg compression problem more a problem with me naively stretching the contrast far too much. I went back to my data, this time gathering and applying some darks, reprocessed, and I believe the result is far better. Although, not nearly as impressive as your image. Your image contains fine detail and impressive subtle contrast far beyond mine.

My results here:

Thank you for taking the time to comment.

Best regards,

Mark
