Wednesday 14th May 2014 - One Second Image of M13
Globular Cluster M13 - 1 second exposure. |
On Friday May 14th 2010 I was still using the 12" Meade as my main instrument and was focusing the telescope on M13 using 1 second exposures and realised how much detail was captured in that brief time. M13 was high in the Sky (Airmass 1.064 - 70 degrees altitude) which makes a huge difference in Leyland due to light pollution nearer the horizon - as well as having less atmosphere in the way). I decided to save this raw image (ie no image enhancement or processing) just as a record of what can be captured in 1 second with a 12" OTA and SBIG camera at -5 degrees C.. Len Adam |
