M42 with cooled DSLR (only in winter)

-17°C (about 1°F)...this is my personal record so far while stargazing ! Who said astrophotography isn't an extrem sport ??? ;-) Under fair transparency, I was able to manage 1 hour of good data between clouds at our usual location a few kms away from home. Two of my best motivated companions and I spent about 4 hours under the sky after almost 6 weeks of bad weather. Despite the extremely low temperature, we were excited to use our astro gears and share both visual and photographic targets of the winter season. DSLR was "air cooled", so raw images didn't show so much noise at all ;-P

So, this is my 2nd attempt at the most iconic feature in Orion, just 3 years after my first image of M42 making my step into this amazing hobby! I'm pretty happy with this 2021 version and all the way I've made in 3 years, from field integration to post-processing skills. So, thanks everyone here for your faithful support and motivating encouragements ! :-)

Funny fact : after packing all stuff back in the boxes, the eletric tailgate of my friend's car didn't cooperate at all...I had to drive back with open door :-))) Fortunately, mine is an manual-operated tailgate ! On the way back to home, we reached a -21°C zone where no one would have to stop (see rev. C)!

Stay well and healthy,

Christophe

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.
