Moon with Telephoto Lens

Crescent moon - 100% crop from 8(?) stacked subexposures_ _ _ _ _ _ _ _

Image Scale = 1.11 arc-second/pixel _ _ _ _ _ _ _ _

Date: 2011/05/07_ _ _ _ _ _ _ _

Exposure: 8(?) out of 13 x 1/80 sec at approximately f/9, ISO 100 _ _ _ _ _ _ _ _

Lens: Nikon 800mm f/5.6 ED AI-S at about f/9 (seemed sharper than f/5.6, f/8, or f/11) _ _ _ _ _ _ _ _

Camera : unmodified Canon T2i = 550D _ _ _ _ _ _ _ _

Mount: Astro-Physics AP900 -- rough polar alignment (no drift alignment) _ _ _ _ _ _ _ _

Processing: Focusing via EOS utility live view, exposures made from live view mode (EFSC active, so no mirror slap or first shutter curtain shake?). 13 individual shots cropped to 1800 x 1000 with Photoshop CS4 to do rough alignment (Registax does not like exposures unless they are approximately aligned first). Alignment and stacking in Registax 5 with "50% drizzle". The intention was to keep the best 8 out of the 13 frames in the stack (there was no confirmation of this). The stacked output was saved as a single 3599 x 1999 TIF, and then "wavelets" processing was done with the default settings. This seemed to have no effect, so the wavelets output was ignored. Photoshop CS4 levels adjustment and unsharp mask processing was done, along with downsizing back to 1800 x 1000 and JPEG conversion (quality = 11). No useful colors were present, so the image was completely desaturated.

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.
