LBN 569 (Reg Pratt)

LBN 569

LBN 569 sits 9° from Polaris near the point of Cepheus. Its a small part of a very large structure of Integrated Flux Nebula that blankets the entire northern celestial pole. This is same extra-galactic dust present in my image of open cluster NGC 188 (7° away). When looking at the 2 fields one thing jumps out at me immediately. The IFN found around NGC 188 is basically void of color while LBN 569 glows golden and there are even hints of red present in a few parts of the frame. My guess is that the golden hue is largely, if not mostly, due to the dust being illuminated by the class M3 variable star V438 Cephei. Don't quote me on that though. I'm just a bro with a telescope, not an Astronomer.

I also collected 25 hours of hydrogen-alpha data which revealed that the entire dust structure contains a weak but detectable amount of HA. Unfortunately the signal was too weak to be of any use though. This HA could also be contributing to the overall color of the dust especially since patches of it are visible even in the RGB data.

For me the cool thing about this field is how the golden glow of V438 Cep contrasts against the cold blue glow coming from nearby pair of blue stars above it. I tired to get some info on those stars but after 10 minutes in search engines and sky surveys all I was able to find out was that the blue star on the right is HD 208020 and it is apparently also a variable star.

This was an extremely difficult target to process. I didn't get anywhere near the vision I had in my head but when I look at other imagers attempts its very clear that this region of space is not for casuals and the result I got is pretty good so I'm trying to shake the bummer of a feeling one gets when they feel they've miss the mark on an image.

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.
