M42 from my balcony

Orion Nebula from my balcony with beginner telescope and manual tracking on a regular tripod ballhead.

Actual subexposures were 1/4 sec; so the total integration time is 2 minutes. I had to put 1 sec because Astrobin does not accept non-integers for exposure duration.

Also it was my first time using PixInsight for processing, really excellent software.

In hindsight, I should have used a lower ISO; noise reduction took a lot of fiddling with PixInsight and there is still quite a bit noise remaining in the final image.

Also perhaps a longer exposure duration would have worked better, I went with 0.25 sec because I was worried about trails. Most strict NPF rule calculation for this focal length and sensor suggests 0.5 sec would be fine, I feel I could have gotten away with 1 sec exposures.

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.
