Eta Car / Keyhole comparison??
Hi guys!
I was wondering.....i was reading in Aust Sky & Telescope, May/June 08, page 78, of David Malin's reprint of HC Russell's Eta Carinae photo and wondered if anyone had an enlarged photo of this they could compare side by side with recent pics to see what, if anything, has changed in the 120-130 years since.
From what i can tell about HC Russell's pic i can see the dark nebulosity region from which the name "keyhole nebula" came about, unless i have it totally wrong!?
I'd be interested to see how they named this "keyhole" nebula any other way other than the dark nebulous region in the vicinity of Eta itself.
Does anyone have David's photo to be able to compare the nebulae to a recent image????
Thought this might be worthwhile having a peek at!
Cheers!
