DAYSTAR Filter QUARK Chromosphere Tuning

I went out to the Observatory yesterday and shot a sequence of image with my DAYSTAR QUARK Chromosphere, one for each 0.1 angstrom detente on the dial. I shot from blue to red, or counter-clockwise.

I used the Explore Scientific AR152 and ZWOasi174. With the QUARK's built-in Barlow this yielded 4,248mm focal length at f/28. I captured 1,000 14 bit serial frames and stacked 12%.

I also used 3x drizzle, so there are some stacking artifacts in the images. Please ignore them as they are not relevant to what I was trying to illustrate here.

I timed the length of time it took for the QUARK to settle on each knob setting going from +0.5 to Zero and then from zero to -0.5. It was 81 degrees in the POD when I took the samples.Here are the results.

+0.5 to +0.4 = 7m 13s

+0.4 to +0.3 = 6m 18s

+0.3 to +0.2 = 6m 24s

+0.2 to +0.1 = 7m 26s

+0.1 to +0.0 = 7m 22s

0.0 to -0.1 = 7m 14s

-0.1 to -0.2 = 7m 02s

-0.2 to -0.3 = 6m 52s

-0.3 to -0.4 = 7m 03s

-0.4 to -0.5 = 6m 46s

So, on average it takes about 7 minutes for my QUARK to settle on a new temperature setting at 80 degrees ambient temperature.

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.
