My very first h-alpha experiments under the bright moon and between some clouds.
Perfect time to test my eos-clip filter which i got from another astrobin member over a year ago.

It was hard to get into perfect focus with this filter, because i could not see the brightest stars through my camera.
The focus without the filter seems to be minimal different as with the 1mm thick filter.
First i tried it with some testshots an minimal focus correction moves in between to get the perfekt X, this worked okay but
after the moon went up, i could easily focus on him and had time for i few pictures.
Any ideas to make this focus process easier or when the moon helper isnt there?
I think jupiter would work as focus point to.

Nearly unprocessed image, only luminance extraction and little strechting.
I like my first result, although short integration time and very noisy.
Impressive what you can get with such a filter under a very bad sky, i love it!

Description: Tested a deconvolution method with PI for more sharpness.
Little MLT noise reduction and soft curve modulation after streching.

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.
