Hello,
With a bit of hard work and a lot of help from Avistack, I had a successful session with our Sun today, 24th January 2010.
The early morning session was marred by generally poor seeing, characterised by high frequency, large amplitude scintillations that did not bode well for the remainder of the day. Leaving the gear set up, I periodically ducked in and out of the house to gain some respite from the fierce Sun. Later in the morning, during my 10 minute forays at the ‘scope I noticed that for periods of a couple of seconds or so, the seeing eased, with longer wavelength, smaller amplitude scintillations allowing some quite wonderful detail to poke through.
I unsuccessfully attempted to collect the best of the seeing by pausing/re-starting the recording of the AVI’s but as my Notebook computer only display every n’th frame from the 1024x768 pixel DMK31, it proved nigh impossible to respond to the good seeing in a timely manner. Manually re-starting the recording often lagged behind the moments of best seeing as they did not last for more than 1-3 seconds.
However, a couple of the AVI’s were a few kB larger than the rest and so I processed these to obtain the following results. The full solar disc is a mosaic of 2 frames with the Canon 40D.
All in all, a very satisfying day at the office!
Thanks for looking!
Dennis
