New gear and no clouds - unparalleled. I swapped the collimation screws with Bob's Knobs. An absolute must, they should be standard. Not sure whether my collimation is correct but the defocused star Fomalhaut looked concentric to me. Next, I got a new barlow lens. Oh, no, no new telescope or camera.

Originally designed for William Optics' bino viewers these "nose piece barlows" are a great addition for lunar and planetary imaging. As the name suggests, the barlows are threaded to the 1.25" nose piece of a planetary camera in that the barlow is fully inserted into the telescope which helps avoid tilt. Since a nose piece barlow is directly attached to the camera and pushed into the scope the magnification is significantly less than indicated but can be enlarged with extension tubes. The illustration showcases the magnification factors as compared with a standard form factor barlow lens. Planning accurate measurements as weather recovers.

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.
