NGC281 - PACMAN NEBULA

I wanted to try a newly acquired small catadioptric lens (90 euros...) of 300mm f/6.3.

This is a Maksutov build lens, so there is already lots of obstruction, but I also added a 2'' Astronomik UHC filter on the 62mm ring, therefore smaller than my entry pupil... so there is even more obstruction (losing about 2 additional stops).

That being said, it is very lightweight and has fit perfectly on the Skyguider pro with my Sony A99.

I have shot 240 images (on 13 of them there were some leaves of a tree on the lower right side of the image).

Then processed in Siril and Photoshop to raise the colors... I may try something later with a narrow band SII filter... But clouds are back.

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.
