Sun - 17 Nov 2023 - 1212 UT - test shot of double stack

Acquisition type: Lucky imaging

A test shot of a double stack setup. A TV76 with a Solarscope 50 etalon as per normal, but with a combo quark at the back (with a 2.5x powermate in front of it) so that the quark sees f24 light. The FOV is obviously tighter than the TV76+SF50 single stack alone (which would capture the whole disk). There were lots of newton's rings which thankfully mostly calibrated out as the sun moved across the sensor. Flats were a bit tricky (definitely need an autofocus for that to avoid disturbing the framing). Didn't have time to image single vs double stack so can't really compare but based on gut, it does look the contrast is sharper with this DS than just the SS alone. I'm guessing it would much better with a proper Solarscope double-stack etalon, but this is a potentially interesting first test shot.

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.
