vdB 136

[Tom Davis]

The last few vdB objects were sort of duds, but they are done...time to move on. This is vdB 136. It is one of the uncommon yellow reflection nebluae listed in Sydney van den Bergh's famous catalog. The region of Cygnus that it is in is very rich in nebulae and dust, but one must stretch the data significantly to bring them all out.

Again, this data has been aggressively stretched to show the faint bluish background nebulosity in the area. This unfortunately reduces the overall contrast of the image, but I'm OK with that.

Awesome field. Great colors and very interesting. Particularly like that yellow reflection neb and all the details in the red clouds. Really nice. :thumbsup:

Your stars have consistently the same size in all channels and your blue channel is always very clean. How do you do it. Separate processing?

looks great - like a horse or dragon breathing fire

Stunning work Tom. I actually prefer the colour data rendition you link to in the text description. Wider field expanse suits this busy scene. So much going on and you've portrayed it in all its glory. Thanks for sharing this jewel of the northern sky.

What more needs to be said....stunning image!!!:):)

Fabulously stunning to view! The blue "dust" is apparent and thanks for posting.

A very unique image. A lot of interesting things going on in there.

Nicely done as always.

Nice one Tom although I was just wondering about the colouring difference in the red tones towards the bottom right

[Tom Davis]

This color data is from a OSC camera. I combine the OSC data with luminance data to get the final image. I do this so to increase my production during the few clear new moon cycles that I have.

I debayer the OSC data into R,G,B files and then process each of these as if they were from a mono camera taken with filters. Takes longer but it seems to work for me.

The darker red tones in the lower right had much less data in the luminance channel so it comes out darker and richer in tone. When looking at this area on a map it appears to be part of a dark nebla. I suspect the red tones are from the dark nebula's dust.

Thanks everyone. I'm still getting clouded out in AU.

The ASA N12 delivers again :thumbsup:...oh and Master Davis of course :P

I'm getting close to placing an order for an Orion Optics AG12.....:scared: :question:
