Transit Observation of Exoplanet Qatar-2 b

I've been considering having a go for an exoplanet transit for quite some time and now I have my equipment automated now was the time.

On May 10th/11th the night was clear after some heavy downpours and Qatar-2b in Virgo transited with a light drop of 0.037 of a mag across the mag 13.4 star.

I had tried previously on WASP-113 b with no success as the light drop was some 0.008 of a mag. Processing the data with AstroImageJ was a bit of a learning curve but there a lot of online help was available.

The data is noisy without doubt but I think clearly shows the transit occurring close to the predicted times, the constancy of the comparison stars was also good evidence. Next time I will use the camera unbinned and defocus more to spread the light across more pixels, hopefully this will improve the data. I realise some may feel this is not for AstroBin but several others have posted their results, I think we should encourage all kinds of astroimaging! Hope you like it CS Rob.

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.
