|NGC 1788: Reflection Nebula (Orion) RA: 05h 06.9m / DEC: -03° 20'.5|
Instrument: 10-inch Starfinder
This little gem is tucked away in western Orion just across from Eridanus. 2.8 magnitude Kursa, Beta (67) Eridani, serves as a landmark from about 2 degrees to the south. 7.2 magnitude HD 33223 stands 25' to the east, just beyond the field boundary of the sketch at left. My drawing presents a 129X view in the 10-inch Starfinder Newtonian. NGC 1788 is just north of center. The 3'x2' nebulosity is quite delicate with 12th magnitude star immediately adjacent to the northwest. Among the twenty field stars included in my sketch, the brightest are four ranging from 7th to 8th magnitude. Among these, the brightest is 7.6 magnitude HD 32884 which lies 14' to the southwest.
|Instrument: 18-inch Obsession|
NGC 1788 puts on a fine display at 199X in the 18-inch. Irregular in form, this bright nebula covers roughly a 6'.4x5'.7 area. 8.4 magnitude HD 32911 stands sentry near the west field boundary while 8.9 magnitude HD 33056 blazes just inside the east border. The five GSC stars south of NGC 1788 range in brightness from low-13th to almost 15th magnitude. The remaining ten field stars are mostly 14th magntiude embers. Two fairly bright stars lie enmeshed in nebulosity. The northern and brighter of this pair appears similar in brightness to the two Henry Draper stars, in the mid-8th magnitude range. The other is about a magnitude fainter, by my estimate.
