Antares and region preview (Morocco - Atlas Mountains)

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!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
