I was really uncertain if to public this image. This is the first one taken during our tests of the Veloce RH200 in Austria last september. It has been taken during two nights. On the very first night the telescope was slightly misaligned and we had a bad filterset, causing strong haloes and rings on bright stars. The resulting frames had stars slightly out of focus on one side and in focus on the other. On the second night we had the telescope collimated and with a new filterset so the frames where good enough but we had bad seeing and subtle fog. A lot of gradients comes out. In the end, processing of the image was a true nightmare! I decided to publish it anyway 'cos I think, despite the overall quality wich is bad to me, the field is really interesting (4.5° diagonal) and inspiring. The whole area is filled with dust and nebulosity and structures.

Thanks for watching this so so image...

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.
