Observation of 103P/Hartley by Elizabeth Warner using her telescope and camera, Observatory computer at the UM Observatory, College Park, MD.

Approximate start time of Hartley imaging:
02 Oct 2010 23:50 UT = 02 Oct 2010 19:50 EDT

152mm AP refractor with a telescompressor on AP900 mount

ST10 w/CW10

Clock battery had died in the computer some time ago, so I used my laptop to access the internet next door and set it (www.time.gov), then used the laptop to help set the desktop computer. So, times on these images should be good to within a sec.

Filters:
I bought the camera used and it came with the CW10 already installed... supposedly has LRGB, Ha, OIII, SII, .... BUT, the version of MaximDL that we have on the desktop to control our other SBIG cameras is an older version and doesn't let me add the CW10 ... it sees the filter wheel (I think), but I wasn't able to change the names of the filters from what was already set... Long story short, the other camera that we have is an ST8 with a CW8 and it has Bessel R, Bessel V, 


software thinks the filters are in CW8 and
 1) Bessel R
 2) Bessel V
 3) OIII
 4) Ha
 5) Bessel clear
 6) empty
 7) empty
 8) empty


Actually have CW10 and I'm pretty sure the filters are in the following slots
 1) Luminence
 2) R
 3) G
 4) B
 5) Ha
 6) OIII
 7) SII
 8) empty
 9) empty
10) empty

There is a UV/IR cut filter as well (visible when I look into the nosepiece) and it keeps me from actually seeing the filters (without completely taking the filter wheel apart)...



So anyway, I think that I've mapped over the filters correctly. The header will have the wrong filter, but the extension should be correct. Ie, if you look at H2-030L.fit, it will say it was taken through the Bessel R filter but I'm pretty sure it was with the Luminence...

Used MaximDL to collect the images.

Started with trying to get skyflats... most were overexposed and then just a few weren't but also started getting stars (which are trailed because I had turned off tracking)... I only included the flats that weren't totally overexposed.

30 X (60s each LRGB, dark), bias

had sidereal tracking while imaging the comet...

stopped after 30 sets because ... long story...
