North America and Pelican

My first time using a lens with my ASI1600. Since this was just supposed to be just a basic test of the equipment, I did not have dew heaters installed at the time, so the lens fogged over and I lost over 2 hours because of poor image quality. So this image is composed of only 7 frames that were any good before the dew covered the glass.

Next time I hope to be better prepared for the dew and have my heaters installed. The problem is where I need the heater strap to be installed is right over the focus grip. So I am worried about accidentally adjusting focus while it’s wrapped around the grip.

I did not take flats for this image, as I'm not prepared for that yet. All I did was stack and apply a round of noise reduction before stretching and saving for upload here. I did not crop the image at all (only a rotate), so this is the full frame I can expect from future targets. My image scale reported by Astrobin was 9.26"/px, but this is because I used 2x drizzle. My actual scale is 3.9"/px.

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.
