This image is the second succesful image I've taken within two weeks where I feel alignment and focus were acceptable. I decided to see if I could get an image of SN 1998s using a piggy-backed 600mm f/8 Sigma mirror lens. I am working with black & white film because I can process the film immediately and see whether I was succesful or not. My darkroom consists of a changing bag, a 35mm developing reel and chemistry. The negative was scanned using a Nikon Cool Scanner.
The black and white image shows a wider field while the negative image provides a better view of NGC 3877 and SN1998s.
