Hi
Well, now that the Tak reducer/flattener had arrived, and the Adapter to fit the ST7E CCD camera, there was no excuse for not going outside (Sat 29 Sept 2007) to put them through their paces. Except for a full moon and very heavy dew that is. Anyhow, here are 2 galaxies NGC7599 (11m5) & NGC7590 (11m3) from the Grus Quartet.
Tak Mewlon 180 (1800 F12 DK) on Tak EM200 mount.
Tak x0.8 RC (F9.6), SBIG ST7E (parallel) CCD camera.
First light for home built LED flat field box.
5 mins exposures self guided with ST7E. Total 45 mins.
9 sub frames dark subtracted, flat fielded and combined in MIRA AP6.
Finishing in Photoshop CS3.
The almost full moon, too few frames, not quite enough exposure and suburban light pollution has made the results a little washed out and grainy, but things bode well for the future. Now if only I had an ST8.
Cheers
Dennis
