VDB 149 Shark Nebula

This one is an attempt at this quite faint nebula... As always I've never had enough time to make a proper exposure time but, instead, I've managed to include several sessions done along the years plus I've included exposures that my good friend Maurizio Mollica gave me. His setup was using a refractor scope (a Takahashi TSA 102) and the night He made his exposures was not the best one in terms of seeing. Mine too has different quality in terms of good seeing or trasparency sometimes thus the final image has "strange" stars a little bit bloated... Anyway the overall result seems quite interesting and I've decided to publish it. My exposures where acquired mostly with my moving setup with the Takahashi Epsilon 210 f3 and QSI 683 WSG8. Total integration time including Maurizio's frames is about 7 hours total.

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.
