IC1218 Around Sadr star

Hi everybody!

Today's image is really nothing fancy but it's the only image I was able to get after this very long and restrictive pandemy...

I was partecipating a small star party in Italy for just 2 days in the good sky of Umbria. During the first night we've had a very dark sky with good seeing but full of passing clouds so no long exposures where possible and I've spent the whole night taking "just for fun" 60" RGB's of very bright an famous Messier objects to show to people. The second night was clear of clouds but with a very bad transparency and a lot of dust and sand in the lower atmosphere due to very high pressure, strong wind gusts also make long exposure impossible. The seeing was excellent (in some moments even below 1") but really no dark object was really an option. At about 2.30 A.M. the sky was clear enough to try to make some shots but the night time was just about 2 hours at least... I decided to go for something near the zenith and try "just" RGB for personal fun and I've chosen the Sadr region containing IC1318 "butterfly" nebula. The end result is just 4x600" exposures in each R, G and B filter and the last images laks of contrast due to the incoming down. I was surpised anyway from the results... The image is nice and pleasent to the eyes and the seeing helped a lot. Low contrasts and light scattering is present still due to dust and vapours but, a part from some halos on the stars, it helped the star colors. Anyway, this is my result on IC1318 with only 40' of datas for channel in straight RGB.

Thanks for watching!

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.
