Rho Ophiuchi Cloud

Making this photo was a rather difficult job for me as, once the rgb photo was created, I could barely distinguish some vague color of the various nebulosity, everything was immersed in a disheartening haze. Unfortunately, this did not surprise me too much as my shooting area, even if very dark and on a mountain about 1000 meters high, is in the south of Tuscany and consequently the nebulosity that I filmed came to me at a maximum height above the horizon of only about 23 degrees and I started shooting with only 16 degrees above the horizon! Even if taken a little by the discouragement, given the first color photo, I did not give up and I used some elaborations that I had never used on other astronomical subjects, in particular it was of fundamental help the use of Starnet v2 which eliminates all the stars, after I put back only the brightest ones and the star clusters, by doing this I greatly increased the visibility of the details of the various nebulae and some, which were hardly visible, later turned out to be very evident. The use of the h alpha filter for 3 exposures of 30 minutes was very important to give brightness and details to the red nebulae. Everything else was done using rgb filters.The use of the excellent Samyang 135 mm F / 2 telephoto lens that I was able to use at maximum aperture and the Neq 6 mount that allowed me to shoot in the presence of always very strong wind was of great help. Finally, I must say that I was really surprised by the result as I thought that to get something similar you had to go under the skies of Namibia.

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.
