Stepping out in the scorching heat of Kuwait at around 2pm the temperature was around 45 degrees celcius, however I had to image the massive sunspot AR3363.

Rushing to connect all the equipment in order to attempt to minimize the affect of the heat on the camera and sensor I managed to collect several images each consisting of 2000 frames at 120FPS.

To put the heat in perspective, I even managed to burn my hand slightly while removing the grub screws which secure some of the equipment to the telescope.

This however was all worth being able to witness the massive sun spot on our local star.

To show the massive scale of sunspot AR3363 I included scale images of Earth and Jupiter.

Equipment used:

Lunt LS100MT solar telescope
Zwo asi174mm planetary camera
Televue 2.5x barlow
rainbow rst-135 mount

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.
