Rosette Nebula in HaLRGB

The LRGB was taken over two nights from the Mojave Desert, one night at Amboy Crater and another night at Cadiz Dunes. The HA subs were taken over four nights from my backyard in Los Angeles.Still fine tuning my garage built astrograph. Appears I had some pinched optics, gotta make some tweaks to my mirror cell design. Also some elongation in one corner due to focuser sag. Current focuser is a JMI Ev3n, not quite up to the task. Wish Moonlite had regular CR2s, may have to switch to a Feathertouch or perhaps that newish Baader Steeltrack. Collimation was already critical at f3.9, now that I'm near f3 with the reducer any tiny deflection makes a difference. The qhy268 + CFW3M is much heavier than my previous camera, a Canon 6Da

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.
