| Eccola: www.cloudynights.com/ubbthreads/sho...22/Main/3410727Si dovrebbe apprezzare la sagoma ad altissimi ingrandimenti, seeing permettendo. Aggiunta IC 4954. CITAZIONE IC 4954 Pretty bright, pretty large and irregularly round with the UHC filter at 100X. There are 17 stars of magnitudes 11 to 13 involved. This nebula is about 10 arc minutes in size and has several bright knots within the nebulosity. Aggiunta Abell 74 www.capella-observatory.com/images/PNs/Abell74.jpgCITAZIONE PK72-17.1 (Abell 74) It is very faint, large, irregularly round and not brighter in the middle at 100X. It is just seen without the UHC filter. Installing the filter helps quite a bit. On an excellent night, some dark features could be suspected with averted vision and the UHC. Aggiunta Sh2-88 www.astrofoto.ca/john/files/sh2-88.jpgCITAZIONE Sh2-88 Pretty faint, large, elongated 3 X 1 with the UHC filter at 100X. It is just barely seen without the filter, there are 11 stars involved. This streamer of nebulosity extends from one side of the 30' field to the other side. It is actually a very nice nebula, for one that is so little known. (S. Coe) |
