LBN468 - with Tele Vue LCL1069 corrector

Dark nebula the LBN468 located in Cepheus constellation.
Nebula looks like jagged ring. On image are visible the Bok
Globule which are places where new stars born.
Image is a first from planning mosaic from LBN468 (on this image)
through NGC7023 (Iris Nebula) to VdB141 (Ghost Nebula).

Second approach to this object with different telescope configuration,
during this sessions was used TeleVue LCL1069 corrector. The image
field with it is smaller but stars correction on image corners and
final resolution per pixel are better. Images had been taken during eight
clear which happened nights across three months.

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.
