The sky was good yesterday night, but very windy.

I had to use my car to protect my gear from this ****** wind (see my previous picture) ;-)

This time I used my complete setup :

A7Sa at 3200 ISO

Nikon 300 mm at f4

Star Adventurer

Lacerta MGEN II for guiding, dithering and driving the camera.

136 x 30 sec.

Bias and Offset, no Dark (the dithering is very efficient!)

100% processed with PI, using drizzle x2, and reduce by 50% with PS.

Maybe not enough integration time, but I'm quite satisfied with the result.

Description: Some adjustments :
- first, crop of stacking defaults (bottom and let side of the picture) I haven't noticed in the first version ; Have you ?
- a bit more color saturation
- a bit brighter
- resolution reduced to 75% from the drizzle x2 image (previously 50%)

I think I like this one ;-)

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.
