The mandatory Andromeda picture!

Conditions were not that good, lots of lightpollution tnx to the high humidity. Clouds were drifting by, with the sky completely covered by times. in addtion the guiding went completely bezirk for unknown reasons, maybe bad cable management: 3 to 4" jumps in the PHD2 graph and sometimes RA or Dec going totally off chart! nice...

Anyhow pleased nevertheless, it could use a lot more data I guess: this is only 45 minutes ; main objective was to test the 3" TS0.79x Focal Reducer of the FF Nikon. Stars are pretty sharp overall, but there is some noticable vignetting that needs to be flatted out ; also visible in the subs is an interaction with the Optolong Pro LPS filter giving round interference gradients. A remnant of that is visible in the upper right corner of this image.

the F5 versus the F7 should however result in about 2x faster imaging ; I'm not sure how the pixelscale of 2,2"/pix versus 1,4"/pix will be noticeable?

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.
