Markarian's Chain & Neighbors

This is my first published image with the ASI071MC Pro and Sequence Generator Pro - and with cooled cameras in general. Lots to learn with this new camera and SGP.

* The 071 is much more sensitive than my DSLR (duh) and I am wondering if it picks up more dust imperfections farther from the focal plane. There is at least one "circle" in this photo that is pretty obvious. Looks like I will have to start shooting flats with each image. I was able to reuse flats with my DSLR for a year or more sometimes.

* There were some issues with earlier targets and the camera driver used by SGP. The driver named "ZWO Camera" (which I think is the ASCOM driver) seems to work best.

* I think the trailing was due to a balance issue. The AVX is a nice entry-level EQ mount, but it can be tricky to maintain balance. I'll have to rebalance to see if that helps.

(If anyone has any PixInsight tips to clean up some of the trailing, let me know. I'll give it a shot.)

* HUGE THANKS to fellow Astrobinner Jonathan MacCollum for his help with getting started with 071 camera. He does great work with it - check out his gallery.

Thanks for looking and clear skies,

Pat

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.
