8 exposures of 7 minutes each made between September 1, 2008 23:55UT and September 2 1:18UT from Puimichel in the South of France
Between exposures I let the camera cool down for 4 minutes to keep the noise low. Temperature was around 17°C and the SQM reading was 21.3 mag./square arcsec.
Images made with a modified Canon 40D @ 800ISO and a 20cm F2,75 ASA Astrograph
100% crop from the previous image.
2008 J1 Boattini, 15 x 2 minutes at 1600 ISO with a modified Canon 40D and a 20cm F2,75 ASA Astrograph. Images acquired August 23, 2008 between 22:23 UT and
22:57 UT. The sub exposures were unguided, using the 10Micron GM2000-QCI mount in "Follow Object" mode. The last quarter moon was above the horizon,
but despite that I still measured a sky brightness of 20.2 magmitude/squre arcsecond at the zenith with the SQM.
