Hello,
I was out practicing for tomorrow's total lunar eclipse using the Tak Mewlon 180 and Pentax *ist DS DSLR. Sadly, the results were not very good as the mirror slap caused too much vibration, even with the 2.5 sec delay set on. It seems you really do need a mirror lock up function on shutter speeds less than 1/500.
So, I plugged in the DMK and was pleasantly surprised with the seeing – I’d put it around 7/10. Managed to grab a few AVI’s before a thin layer of cloud rolled in, creating quite an atmospheric, mottled effect to the skies.
Here is Aristarchus; slightly pumped, as I’m a little rusty with processing right now.
Cheers
Dennis
