The Angel IFN. My first go at the elusive clouds lurking above our Milky Way!

Friends, long time without quality sky and quality data, so instead of doing some simple and bright nebula I've attempted this, imaging of the Integrated Flux Nebula... Almost 8 hours at f/4 on a full frame sensor still yielded a really noisy stack and I had to convolve most of the nebula using denoise algorithms. I will have more attempts at processing it, and maybe if time allows it, gather more data.

Thanks to Aleksander Kacz's insight (teleskopy.pl) I was presented with this fabulous lens! Its field quality is incredible, pin-point stars up to the corner of a full frame sensor. Also the FWHM and sharpness of a point source at the focal plane is remarkable. I do think this is the best quality lens I've touched so far, and at f/4 it isn't slow. The quality of field is comparable to the FLT156 with x1 FLAT 68 III I've had the chance of testing! (and this would be comparing a whale to a hummingbird)

This picture of the IFN shows how dilute and dim those incredibly large clouds over our Milky Way are. Even though the original data has a lot of color and good detail in M81 and M82 I've decided to stretch it without HDR and masking, just to show where, on the DR scale, this background lies!

Enough babbling on.

Enjoy the darkest f&in thing I've tried to image!

Description: After a long talk with a star astrophotographer, Dominik Sito, I got so many tips I simply did not eat, wash myself, etc., just spent time processing my data. My result, naturally, is inferior to his, but hey, it is fun anyway!

Description: Never can decide, lower bgd or higher brightness. Lower this time.

Description: after a few months I just went back to this for sport, I have decided to remove the color in the background as I think it is not physical, maybe the image is more dull, but oth I think it is now more accurate

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.
