NGC/IC Project Restoration Effort

===== NGC 4090 is not IC 2997 (which see). Both were seen on the same night by Bigourdan, though he included only his observations for I2997 in his big table. The observations for N4090 are in his Appendix VIII of complementary observations. Another curiosity with this object is its NGC right ascension from d'Arrest's observation. D'A found both this and NGC 4086 on the same night, and mentions this object in his note for N4086. However, while his RA for N4086 is about right, he puts this object about 10 seconds of time following its true position 1.5 seconds preceding N4086. Since both are visible in the same eyepiece field, I suspect that this is a simple digit error somewhere in d'A's reduction.

===== NGC 4090 17.5" (3/28/87): faint, almost round, diffuse, fairly small. A mag 14 star is 1.1' SE of center. Located 3.7' N of NGC 4086 within the NGC 4065 cluster.
