This region contains LBN 634, LDN 1333 and the open cluster Berkeley 8. These are the only objects with major catalog designations in the 3 plus degree wide field. However, there are a significant number of dusty structures in this region. I highlighted structures that are designated in the TGU and PGCC catalogs (in the annotated image). There are also a number of background galaxies that surprisingly shine through all the Milky Way dust.
The image is a two panel mosaic. I learned a bit on this one about the
SGP framing wizard and doing a mosaic close to the pole. There is, of course, a frame rotation on east/west side by side panels this close to the pole. I didn't think that the
SGP wizard would ignore this. It does, and bad on me for not checking this. So this mosaic is heavily cropped.
Anyway, the basic solution is to make a larger overlap but this seems wasteful. Turns out ther is a better solution, you can modify the required plate solve angle by lining up the east/west interface of the two panels onto an
RA grid line. (In most planetarium programs you can rotate the sensor projection by degree.) In the case of this image, the total angular difference is about 6 degrees. You can see this on the Rev C image on astrobin. In capture, you can use a rotator - or if your setup does not include one, you can use a manual rotation with your plate solve - it need not be much of an inconvenience.
Image and details can be accessed at the link below (or by clicking on the thumbnail image below). The annotated image has a link below but it can also be accessed from the main image webpage as well - or seen on astrobin. The full
FOV image can be accessed from the image webpage and has an image scale of about 1.88 arcsec/pixel.
