 Well, last night was "interesting".    My son had a couple of friends spend the night after his Birthday party (age 10).   I finally pried them away from the Wii and Nintendo DS games long enough to get them outside to look at the moon and Jupiter in his telescope (6" Dob).   He was excited for them to see his telescope and look through it, but they weren't impressed.....just no interest.   He was pointing out various things to them, but mostly in vain.   Even a pretty decent view of M13 didn't make an impression.   He does have one friend with a telescope, and they have fun trading information........trying to impress each other.  LOL 
 
After the boys went inside, I brought out my imaging gear.   That didn't turn out to be very successful either.   My alignment was too hurried, and the sky was washed out with a bright moon and considerable haze.   Seeing was below average.   I had a difficult time getting a decent focus.   As a result, the stars came out bloated and only semi-round and detail is lacking.
 
My goal for the night was NGC 7635, the Bubble Nebula.   I managed to capture some of the nebula, but not nearly what I had hoped for.  I can see that I needed at least 90 minutes, probably 2 hours, on this object.....at least from my light-poluted location.   I ended up with about 50 minutes of useable data......combining 40 sec, 50 sec, and 60 sec subs.   Next, I moved the Bubble down to a corner, to get M52 in the frame.   I managed about 45 minutes of useable data on this shot.
 
*BOY, WHAT A DIFFERENCE BETWEEN THE DETAIL/EXPOSURE TIME NEEDED AT OSP VERSUS WHAT IS NEEDED AT HOME.   ALMOST NOT WORTH THE EFFORT AT HOME.  CAN'T WAIT TO TRY THIS OBJECT AGAIN FROM HANCOCK IN SEPTEMBER.  HOPEFULLY WE'LL HAVE CLEAR SKIES.
 
Equip:
Orion 80mm ST refractor, Celestron CG5 GT mount (unguided), Orion StarShoot II color CCD.
