This particular subject has been on my to-do list as well as in the Unfinished Business folder for good many years, from 2005 in fact. Tried it, couple of hours then other things took precedence and this rapidly faded in the background. Truth is I couldn't be bothered. With resumption of activities in the past year I swore to myself that I would complete what I started and here we are. Main issue is, I think, I was sold a dud (thanks Markus!). For all it triplet prowess this APO can't hold a candle in terms of sharpness to a 72ED because something somewhere dislodged itself. And there is very little I can do about it. I'll try nevertheless to improve collimation but I'd need an optical bench to get to the bottom of it. And it ain't worth it.

All exposures in rather sub-optimal (and I am being charitable) conditions. Winter in the UK.

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.
