M52 and the Bubble

first light for ZWO's ASI1600MMC camera! Here a LRGBHa shot with a 70/350 Apo under almost full moon. Ivo's APT was used to control the camera, and it worked like a charm. The cam is easy to handle, the calibration frames can be taken fast. Thanks to global shutter the flats can be taken with 0,05sec exposures using a LED Flatfield box. The ASCOM driver scales up the raw files to 16bit by just multiplying them by 16, which was a little annoying at first. i do not like raw files being touches by some automatism. But I compared by dividing them back, and the resulting master frames were quite the same.

By choosing low gain you can get best fullwell capacity, which I did here: Gain Zero. By choosing Gain maximum you get lowest readout noise, so you can use very short exposure time and try lucky imaging. A versatile camera!

LRGBHa 11/4/4/4/12x8min at -20°C

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.
