NGC 7814

This cool little guy in Pegasus is a lenticular edge-on galaxy. It's just about 5 arc-minutes big, one of the smallest targets I've ever imaged (last one being NGC 2276 at 3 arcminutes). I had (still have) an issue with the stars. Focus dropping over night is a big issue that I'll get to soon, but for the longest while I thought I had tilt in my sensor or my focuser. Everything was squared up to the optical train, so what was it? My Off-Axis Guider prism. I hadn't paid attention to the fact that the OAG acts like another diffraction spike for my stars, creating ugly shapes in my stars the closer you got to the OAG. I'm going to find the correct orientation next time, but that was a very big issue. Next is collimation, which was okay but not entierely perfect. I'm going to do away with a laser and do it by eye next time, so we'll see how that goes.

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.
