So, I have to do a bulk upload.. I have "ignored" my blog for some time, just had a lot of work to do with my house and job and and and.
The images are done from march to September this year and the stacks are from 20 to 45 single images each 900 seconds long.
Stacking have been done in DeepSkyStacker (the last beta version) with some aggressive values set for sigma-kappa clipping and it seams that I am close to the optimal setting for stacking narrow-band images.
Post-processing done in Photoshop.

Enjoy the images and apologies for not tagging (yet) my images ;-)

So long story in a shorter form, the local garden stuff store has also some smaller build it by yourself - garden houses and the had on stock one with the dimensions of 2,7 x 2,0 m. I wanted it a little bit bigger, about 3,5 x 3,0 m but, because the delivery time was stated to be about 4 weeks and october was at the end I had to act so I did buyed it.      Fortunately they could store it until I was ready with the pier and the other...
