I do not believe it! I went after the same target this evening but the
seeing is very poor and I had to abandon my session (clouds are also now
rolling in). This always happens when the transparency is exceptional as
is the case this evening.
This one is a real toughie due to the fact the brightest stars within
the core are only mag 19 and 20! You have done a really good job at
capturing the dwarf galaxy.
If you are up to it, take a look at the Ursa Minor Spheroidal Dwarf as
well which is equal in difficulty with the Draco Spheroidal Dwarf. For
the former, you can center your field of view on GSC 4186:130.
Keep'em coming. (I am supposed to have clear skies tomorrow evening
and I will be back after the Draco Dwarf, UGC 10822, once again)
