Flaming Star and Tadpoles (IC405 & IC 410) with RASA 8

This is from early Friday morning. After my first object of the night had disappeared behind the obsy wall, I aimed at these well known and much photographed nebulae. Mainly because they were in a good position in the sky and would stay in sight for the rest of the night. The moon was nearly full and I started the exposures around 01.45 and whent to bed. When I looked through the subs it was clear that there was more contrast after around 03.45 and realized that the moon then had gone down. So, I throw away the first two hours and stacked the last 2.7 hours I got until sunrise. Not that the first hours were really bad, it is apparently possible to shoot with the IDAS NBX dualband filter also under a moon light, but they would probably have had a negative impact on the end result. I decided that with these bright nebula and the RASA at f/2, 2.7 hours would probably be quite OK. I had to give the blue and green channels an extra stretch to bring out the blue reflection nebula in IC405, and still it looked a slightly anemic so I added a bit of my old DSLR/refractor data to that area.

Description: This one is for pixel peepers (like me). I got help from the PI wizard Wim Van Berlo to make the smaller stars rounder. I think the issue arose from the camera not being fully centered.

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.
