H-Alpha first session was created by jimmy2010
hi all, greetings from county mayo! it's been a while since i turned up. weather and work been a major factor. i had my first imaging session with a coronado solarmaxII 60mm double stack scope and DMK mono camera on sunday the 27th, and i have to say i have been very pleased with the outcome. actually better than i realised seen that the sun was only 12 degrees or so above the horizon at the time! anyways here is two pictures i cropped of active regions in the northern hemisphere. some nice filments changing over a very short period as well. did capture a small bright flare at sunspot 1358 as well, will post an image of that soon. now just hoping for another clear calm day!

partly cloudy skies tonight! :scope: :stooges: p.s. i love these little animated icons lol.
James.

here is another image that shows two different time frames merged together between 12.02 and 12.46GMT. sunspot 1358 shows a small bright flare in the upper image taken at 12.02GMT. the small flare lasted about 4 minutes.

i recorded about 1000 frames on average in each clip. exp was set at 1/769, and gain was about 650. it was my first time using the coronado so will see how i get on with a 2x barlow sometime. do you know is their any focual reducer that i can use to take in the hole solar disk? at the moment i can only image a third of the sun at a time.

some rainfall here tonight!
