Narrowband image of an old favorite...
- Last night's imaging effort was a short narrowband sequence of the
HorseHead Region. Imaged with the FSQ-106 and STL6303E, single
exposures of 60 minutes H-alpha, 15 minutes SII, 15 minutes OIII,
autoguided with an ST402me on the TMB152. The seeing conditions were
lousy, but it was still fun to image one of my favorite objects.
This image was cropped about 50% of the original frame:
The mounting of the FSQ on the TMB152 is working out well. I'm
currently using a pair of Losmandy 3-point rings, with the aft ring
securing the FSQ tightly at its focuser, and a rubber interface at
the dew shield to keep the scope from sliding back. With two counter
weights on the ME, there is just engouh for balance. Although cables
can be routed through the ME, its hopeless for this many wires, so I
have a bundle hanging from the scopes -- tracking however is not
affected. Here is a photo of the setup (sorry for the text wrap):
Comments on narrowband result welcome.
