Why taking only one nebula and one cluster when you can take two of both.....

It's been quite a summer of hiking, biking and astrophotography... I have piled lots of rural sky data that I will be processing as easy and slow as those summer nights...

For this one, I think I had never taken so much data of a single object with the 135 mm (at f2.8), almost 7 hours across a couple of nights. I am happy with the result.... if only, so many stars! whenever I am photographing with the 135mm I always get the frame densely packed with stars and then i always run into the same dilemma "should I take away (probably not as well as I'd like) those stars to emphasize the object or should I leave what Mother Nature, Optics and Electronics have delivered to me...."

In this case I tried to find a sweet spot between both alternatives while keeping color and spirit of the zone of sky it is (after all it is a Milky Way area with lots of stars)... In any case I would love to find some references on processing images from the 135 mm.....

Very happy to share it with you.

Best skies, Guillermo

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.
