Photograph for my new book dedicated to observing deep-sky objects with a 250-mm telescope. All photographs were taken with the same shooting and processing parameters and a total exposure of 10 minutes, which allows achieving similarity with the visual perception of the objects. On this site, they are posted in the album "Ten-Minute Exposures".
Additional descriptions of the objects in the photo will appear soon in a new chapter of the book.
I'm really looking forward to the book's release. You have a very engaging writing style—reading it feels like you're observing right alongside you! In the first book, the objects were described based on observations with a 150-mm Dobsonian, if I remember correctly. And now it's a 250-mm! :)
