As my second project for QHY294M I went for a more challenging target, with a full set (at the time) of HaLRGB filters. I chose this target to see how far I can push the camera and my processing skills, and also because of the fact that I travelled to Bortle 4 area.
Now finally having a mono camera, I can run photometry on my data, and to my surprise, I discovered 3 new eclipsing binary stars. Two of them are Algol type variables, with one of them having asymmetric, time-changing curve shape due to surface spots; the third is W UMa type variable. Phased light curves you see here are from TESS observatory for precise period determination. The stars were submitted to CzeV catalogue of variable stars.

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.
