M1 Crab Nebula in HSO

This is about 7 hrs HSO from the night before last. I hoped to get another 7-8 hrs last night but the seeing was not good. FWHM was over 3 - 3x3 pixels or over 3". So, I gave up and processed what I had. Stars are color corrected HSO too. No time for RGB. 1200 second subs.

I discovered why my image calibration was having issues. I use my ASI6200mm for imaging and ASI1600mm for guiding with an ONAG. There is an issue with the Ascom driver for the cameras where the imaging camera can switch to guider somewhat randomly. Many of my calibration frames were taken with the wrong camera. This doesn't happen if both cameras are connected. But, I would usually have the guider disconnected for calibration frames. The solution is to connect both or unplug the USB cable from the guider. I also read that some use the native driver for one camera. I need Ascom to share the cameras with Focuslock/Skyguard so I can't use that method.

FYI - I have been post processing on my laptop. It has a fast processor but poor, washed out screen. Out at my dark site, I have a new PC and monitor with excellent resolution. I was able to process on that machine this time. It is amazing the difference. I'm not sure I want to bring up some of my recent images on the new PC...I may spend days reprocessing them....ha

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.
