As Finished As I
Can Get … Take 2
Well, somewhat
against my better judgment, which isn't saying much, I found a way to
get all but one of what turned out to be the remaining seven Herschel
objects. Among other things, I found out that one abject that I
thought I didn't have, I actually did as a Messier object; M110 in
fact. So, my missing 8 turned to 7 with that finding. The method I
used to get the remaining 6 (of 7) objects was to shove the focuser
further up on the focal reducer. Basically, the problem is that the
camera just doesn't quite fit between the back of the optical tube
and the top of the base. It would be similar to having a swing set
and the swing hitting the ground when you try to swing. I gained
enough room to get closer to the north celestial pole, and doing so
meant that the camera was within about 1/32 of an inch of hitting the
base. But, it didn't. Now I have only NGC6217 left to image to
complete the Herschel 400 list. Unfortunately, although it's
circumpolar, it's below the tree line. My next goal is to find out
when I might have a chance of success. For now, that's a job for
another day. I'll leave you with one of the 6 I got last night,
NGC40, which is a nebula with strong Ha emission, apparently, since
it shows up so strongly in the red.
NGC 40, The Bow Tie Nebula (if it were green, I would call it the Green Lantern Nebula) |
