Andromeda

As this was the first clear night for a long time, I wanted to get out and get something even though conditions were not good (full moon, windy, and with clouds moving in).

As conditions weren't great, I thought I'd go for a galaxy, rather that the deep sky nebula images that I prefer. I also took shorter exposures than I would normally do.

I managed to get the red subs OK, but guiding struggled while taking the green frames so they took much longer as the image capture kept aborting. The blue frames captured OK, but by then clouds were rolling in.

I had wanted to capture some Lum frames too, but the clouds had fully rolled in by the time the blue was done.

I fairly pleased whith how the result turned out, but it would have been much better with some luminance frames

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.
