Description

Hi guys,

I am very proud of this image. I know this is hard to see without using the 100% view but I spend a lot of time doing cable management and balancing recently until I got it near perfect. My work paid off by giving me consistent guiding of 0.3"-0.4" RMS in both axis over about 20h of imaging now. This was the first image I took after all the changes. This is a result I had never expected to get from my little mount and 9kg payload. This resulted in a lot sharper images (2.3" FWHM / 1.6px) which is probably close to the maximum of my telescope.

In addition this is a first for me. To my astonishment I had never done a HaRGB image before. Now I decided to learn how to do that. It was basically out of necessity because the OIII and SII in this region is apparently so weak that I did not really get a nice SHO out of it (beside the tulip itself). So I gave this a shot. I am extremely happy with it. I managed to get a similar look as LRGB would look like, but the advantage seems to be that you get a lot more structure and structural contrast by doing this combination. In addition in works very well in my medium light pollution location

It only felt bad to not use another 4h of data.

Thanks for having a look,

Sven
