This field has a lot of objects in it and is centered on the Cave Nebula. The 135mm Rokinon wasn't able to quite resolve the Bubble Nebula though. I mainly used the post-processing features of APP to color balance and stretch the image. Startools didn't do nearly as well bringing out the Ha area and I only used it for star reduction and light noise reduction. 72x100s gain 50.

As I was taking the Roki and AT80 out to the mount, I heard a strange rattling coming from the AT80. I took off the dust cover and was shocked to find it was completely filled with dog food! I haven't used it for a few months and forgot to put the dust plug in and while it was in the storeroom, a mouse had used it for its winter stash.

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.
