I was in Morocco again for 4 weeks and returned yesterday back in Holland, this time I collected around 75 hours of useful data on 11 objects. Since I had to work also I saved all the data for processing in Holland.

Here is Antares and the region surrounding it, quick 'n dirty processed to see if my data was good and which issues I could see. The first thing I notice is that the blue stars are giving issues again, possible atmospheric dispersion. I will try to fix the issues in updated releases. Also my tracking was not that good all the time, I had to work with a Advanced VX mount again. But for the rest it seems quite OK.

However, the severe banding I had last time I was there seems to be fixed. My camera went back to Atik and they changed the motherboard, it seems to have fixed it :-).
In addition, I used SGP this time and had everything fully automated which worked great! Some nights I worked on 3 objects with 2 meridian flips and everything went fully automated so I could sleep :-).

Unfortunately my autofocus did not work which I brought from Holland, so there I lost some time and also the focus was not as good since I had to do it manually again... I found that some sets of frames where not focused properly, but I will add them anyways and reduce star sizes with other techniques.

All data was collected high into the Atlas Mountains on 2 different locations, 800m and 900m altitude with a average SQM of 21.6. I had nothing but clear skies as usual there :-).

With many thanks to Hans Hoogkamer and his wife Janina for providing me with his excellent telescope, food, a stay and much more!
