Vivid Nebulae in Orion's Belt

The Horsehead and Flame Nebulae with Alnitak

I spent two nights imaging and stargazing in Death Valley for a little birthday astro trip. We had excellent conditions both nights in this Bortle 1 zone and I only needed 40 minutes of integrated exposure time for this target. I recently made some modifications to my Newtonian telescope, including a small foam mask to block light hitting my primary mirror clips. Previously this had been deforming my star shapes and causing unwanted diffraction flares on bright stars. I was stoked to see my experiment worked as evidenced by the nice symmetrical shape of Alnitak. I’m excited to have made this $500 telescope perform like a much more expensive 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.
