M101 and Pals (SemiPro)

M101 and Pals

Another picture from the tilt diagnostic sessions. I spent a solid two nights trying to remove the tilt from the RASA. The first night I almost had it bang-on, a flat field all around save for just a little bit on one of the corners. Like Icarus I flew too close to the sun, as I decided I could get it perfect. Instead I just messed it up.

So that was night one.

The second night I once again managed to get it pretty decent but this time I had learned my lesson. I decided to test the RASA out on an actual object and by that time M101 was rising. I set the RASA to its task.

Turns out, because I had done all my adjustments on Capella when it was high up in the sky, pointing the RASA at M101 which was still at say 20 or 30 degrees was enough to have gravity introduce enough tilt to screw it all up.

So here is a severely cropped and resampled M101 to try and hide most of that.

The RASA is a heck of a scope. I am shocked that I could get what I did out of 3 hours in Bortle 8. The downside is for a telescope so sensitive to tilt they sure as hell did not make it easy to adjust. Turning off the camera, unplugging it, unscrewing it and then making adjustments only to screw the camera back in, power it up once more and take another picture is just not a winning strategy. I need to find a way to be able to adjust tilt without unscrewing the camera.

The intention was to take this bad boy out to dark skies and do a nice mosaic of Orion but with all these unknowns I decided to shelf the RASA in favour of the RedCat.

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.
