Last April, this column profile the dwarf spheroidal galaxy Leo I, discovered by chance in 1950 by astronomers Robert Harrington (still no relation!) and A.G. Wilson as they were scanning the Palomar Sky Survey. I ended that column saying that "Using the right eyepiece and knowing the field will help you add this dwarf spheroidal to your list of conquered challenges with comparative ease. But don't get too cocky. Spotting its sibling, Leo II is an even greater challenge. But we will leave that for a future column." Well, that future is now.

Thank you for your entry, Phil !

 

I like your Cosmic Challenge book as it challenges me to see things in the night sky with smaller aperture than I thought would be possible. 

 

Your entries make me a better observer.

 

Best,

Kevin

After reading about it in Phil's book, I tried to see it and was successful in my 10-inch SCT. Now I've seen Leo I, Leo II, and Leo III! Sweet.

That's great!  Leo III (or if you'd prefer, UGC 5364 or PGC 28868) is definitely worth hunting down, although the Moon, nearing full right now, will probably push the effort off until next month.  It's at RA 09h 59.4m, Dec +30° 44.6, 5° north of Mu (μ) Leo, the star at the top of Leo's "Sickle."

 

For those who are unfamiliar with Leo III, here is some info: http://server3.wikis...ew?object=Leo A

 

Might make a good challenge for next April...are we starting a trend here? (Leo I was featured in last April's column.)  grin.gif
