Re: (IAAC) Obj: IC 421 - Inst: 4.5-inch (114mm), f/8 Reflector
Hi I would like to let you know that the convener of this web site has a
report under ic 421 on the google search engine that remarks that this
galaxy requires at least a 12 inch scope to see it,so your chances of seeing
it with a four and a half inch scope are not very good. I looked last night
Australian time when the object was on my meridian and could just see a
faint smudge. I was using a 16 inch f 4.5 dob and did not do a concentrated
observation, I will try again on my next observing run. I saw one report
that its mag is +16 but I don't think that is correct. the NGC Catalogue
doesn't give any magnitude for this object. Good hunting.Ron

Maybe a slight impression of a roughly E-W elongation and rather larger than
