Hi All
Thank you all for the wonderful comment's on my last image the Eastern Veil Nebula.
Also thanks to John Noble and John Favalessa for their suggesting's on how to fix my mis shaped star problems, I will try NINA Hocus-Focus and ASTAPS on the next clear night.
Unfortunately the weather here in York has not been kind for the past six weeks.

The Image of M52 and The Bubble was a test shot of only 4X300 lights to see what my back focus was like? I then added one extra spacer 0.50mm to see if this would make a differance to my back focus then the dreaded cloud's rolled in.
My first impression of the Apex ED 0.65X Reducer/Fattener is very positive only problem is back focus this will be fixed as soon as I get a clear night.

I'm delighted how this image turned out for only 20 minutes of integration time, to be honest I spend a lot of time in PI.

Title: M52 and The Bubble Nebula 20 minute OSC (test using Apex ED 0.65x reducer/Flattener ) In PI

Description: This is image before I worked PI Magic.
I just used DBE (Division ) and a Histogram stretch.
If you look in the corners you will see my back focus problems.
I used the magic of PI to get a decent image , which took over an hour to process .

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.
