Description:
This is a 600s unguided sub taken with the Apeture 60ED bolted to a scrap piece of large dovetail and mounted on the CGX-L. The cone error is huge so even with 7 calibration points and 2 All Star iterations there is still a 15 arc-minute misalignment.
Zoom in to see the "seagulls". They look like they should be in the sub-hertz range so PHD might get rid of them. If not, plan B: a CGX-L plus a Starlight Express -AO costs a lot less than a 10Micron, or anything with Rh encoders.

The image will be permanently deleted and cannot be recovered. All its revisions will be deleted too. Are you sure?
You will delete all other revisions (if any), and the originally uploaded image, leaving the current revision as the final and only version of this image.

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. |
This image cannot be submitted for the IOTD/TP consideration.
