The combination of these two objects is often referred to as the 'Question Mark Nebula' although I've opted to leave it on its side for the sake of maximizing the use of screen real estate. See the revisions for that question mark orientation.

It has been nearly a month since my last upload. Like many of you I've been fighting clouds and haze and smoke and equipment issues. I've actually had 7 cloudless nights and collected more than 36 hours of data on this target although I only kept about 12 hours due to poor transparency and the occasional guiding issues. My broken HEQ5 is due back from skywatcher tomorrow and I have to applaud the effort of my TINY AZ-GTi supporting probably 12 lbs of gear and 10lbs of counterweight while maintaining ~2.0 arcseconds of accuracy.

The stars on the edges and corner are a bit wonky as I stacked multiple nights of data while I was experimenting with reducer/flattener distance. At this point I'm happy with where it ended up and I'm trying to obsess less about details like that. I'm trying to appreciate images as a whole rather than pixel peeping. We'll see how long that lasts.

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.
