ASTRO: And yet again a M27 in color (my very first color image!)
Hi all,
I know not beautifull as the one from Rick but sure a try.. Composed out of 3 images in H-Alpha, OIII and Blue... This one is my first try with my homebuild camera to take color shots. I must say the actual imaging is less work than the edditing afterwards. But i think i managed to make it look good in color. 10" SCT @ f/6.3 HOmebuild CCD camera Total exposure time 84 minutes. -- Dirk van den Herik A journey of thousand lightyears starts with the first step. |

But I like it. How did you contruct the camera? -- martijn www.xs4all.nl/~martlian |

Martijn, the filters are places in front of the CCD with a filter wheel i
constructed myself. I am still strugling with the compostition of the color image, it's a learning curve i have to do. I found some usefull info on the web, so perhaps i will post a new version soon. reg Dirk -- Dirk van den Herik A journey of thousand lightyears starts with the first step. md wrote in message .. .

Here's another try.
Some improvements made from instructions on the net. reg Dirk -- Dirk van den Herik A journey of thousand lightyears starts with the first step. md wrote in message .. .

Dirk,
the colour of the nebula looks good to me. Stars are quite blue, but "true" star colours with narrow band filters are very difficult to obtain. Stefan "DvandenH" schrieb im Newsbeitrag el.net...

I managed to get it more smooth, but the nebula turned a bit greenish now..
On the web you see m27 centre in blue or green, wunder what the actual color would be.. But the stars are more natural to see. Don't you agree Stefan? reg Dirk -- Dirk van den Herik A journey of thousand lightyears starts with the first step. "Stefan Lilge" wrote in message ...

It looks great now. Not only star colours are better, but also it seems to
have a lot more signal than the first version. Actually OIII is somewhere between green and blue, so depending on the bandpath of the colour filters it can look either green or blue. Probably it should be somewhere in the middle, which I tried to achieve in this image, where I used OIII both for the green and the blue channel: http://ccd-astronomy.de/temp/M27colourfiltgut.jpg Stefan "DvandenH" schrieb im Newsbeitrag el.net...

Though I was so darned high on the laddar I was finding it hard to consentrate on anything but not falling down. Rick "DvandenH" schrieb im Newsbeitrag el.net...

I have a stack to process because they are the more difficult ones. I do the easty ones and let the hard ones sit for a while. Aging is good for wine, maybe its good for astro images as well! But i think i managed to make it look good in color. Color is always a lot harder with narrow band filters if you are after a realistic color. You did a good job here.
