ASTRO: Propeller DWB 111
First I'd like to mention that I have difficulties posting replies to other
images as my newsserver has not shown any new pictures in this group for almost a month. My posts through spacebanter.com have only occasionally reached other servers. I hope my ISP gets everything running again... Until then I'll post replies through spacebanter. Now let's see if my newsserver at least manages to post my own images: Richard's fine picture of the propeller nebula reminded me that I have not imaged it myself. Unfortunately I lost focus somewhere in the middle of the series, but had to use all pictures to get a usable signal/noise ratio. Deconvolution in CCDsharp and resizing to 75% makes the image look more acceptable. Taken from the middle of Berlin with a 10" Meade ARC at f/5.7 on a G11 mount, SXV-H9 camera, 45x5 minutes through an Astronomik 13nm Halpha filter, 5 minutes each for RGB (with the red channel being a 50/50 mix of 5 minutes red and the Halpha image) The picture can also be found at http://ccd-astronomy.de/temp/dwb111P...rcolourgut.jpg Stefan |
