[Fred Rayworth]

Roger,

 

Good info. I had no idea either.

Did a little quick research on the discoverer of IC 10, and also a few other interesting facts. 
 
Lewis Swift (1820-1913) discovered the galaxy in 1887. Swift was also the founder of quite a few comets, including Swift-Tuttle. 
 
Swift was one of the few to have seen Halley's Comet twice. 
 
I am sure that most already know that Mark Twain was born on the year of the comet and died the year of its return (1835-1910). I have always thought this to be pretty interesting.   
 
The largest black hole in the universe was found by NASA in IC 10.
 
I never imagined this small, mostly unknown and obscure galaxy could be so important...

I think the NGC 470 group is more difficult to observe detail than 891 was and IC-10 is even more defficult to tease out the detail.  So, in the order of easiest to most difficult to observe detail I would rank them 891, 470 group, IC-10.


David and I were speculating as to how IC-10 was initially discovered. We didn't think it was visually, but was probably by photographic plates. This object is not one that would someone would easily stumble across.   


I also took the time to throw the camera at the Horsehead last night. From what I saw on the monitor, I can't wait to see the images from the frame capture. I had the computer in night vision mode so I couldn't see the same detail on the read screen. I could actually see the red nebula that backlights the Horsehead, and it was actually red. It should be interesting. 


Talk to you later.

All,
 
The NGC-474 compact galaxy cluster might seem to be difficult, but to me they are much easier than NGC-891.  
 
They are indeed small but due to good concentration, decent surface brightness and with all being so close together, most will find them to be fairly easy.
 
Fred mentioned in a previous e-mail that he did not have any problem observing this group at one of the last LVAS outings.
