Default ASTRO: UGC 9240/DDO190 A rarely imaged nearby dwarf galaxy

UGC 9240/DDO 190 is a irregular dwarf galaxy in Bootes. It is a nearby
galaxy being only some 9 billion light-years distant and easily resolved
into stars by the Hubble Space Telescope as well as ground based scopes.
I'd hoped to get some resolution but my seeing just wasn't up to it
thanks to my lousy weather for most of 2013. I'll save my fingers by
referring to the article on it at the Hubble/ESA website:
http://www.spacetelescope.org/images/potw1233a/ .

The other dwarf galaxy DDO 187 mentioned in the HST article was imaged,
again on a poor night in May as my last May object. There are 23 ahead
of it. Since I'm processing these in order it will be a month or so
before I get to it.

There are a lot of faint fuzzies in the background but most didn't have
redshift data. All that did are listed on the annotated image.

This is my last March 2013 image. Moving on to April for my last
October post.

Default ASTRO: UGC 9240/DDO190 A rarely imaged nearby dwarf galaxy

I see I suffered from the dreaded Sagan Billions disease. The distance
to UGC 9240 is obviously 9 million light-years rather than 9 billion my
disease riddled brain said.

Rick,

while slightly short of Hubble this is still a faszinating image.
There seems to be a lot of star formation happening in this small galaxy.
I wonder if at 9 million lighyears it might still be considered to be a
member of the local group?
