Orions Belt and Sword

I bought a used Canon 500D in almost mint condition for a real bargain pice. It was cheap enough so that I dared doing the astro modification myself. After reading instructions from various websites, I was able to remove the lowpass-2 filter, and even more important, I was able to reassemble everything. Even though the moon phase is horrbile at the moment, I tried to take some pictures yesterday. It seems everything is working fine, and there seems to be better H-alpha sensitivity now, although it is hard to judge because of the moonlight.

Nevertheless I wanted to publish this picture to get some feedback. I also used the Nikkor pre-AI 180 mm f/2.8 for the first time. With the increased focal length there are a bit more details visible than with the 135 mm f/2.8. The lens was stepped to 5.6 due to moonlight.

Best regards from Switzerland,

Jan

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.
