H-alfa sun & Lunt LS100THa

[Pablito]

Hi everyone!

I owned Lunt LS60THa DS50 and used it for observing and imaging using NexStar mount and Lumenera (LU070M) camera. I had quite good results but aperture fever infected me and some day I decided to get my dream solar scope.
So, I recently bought new solar gear - Lunt LS100Tha scope, HEQ-5 mount and Point Grey Chameleon (B/W) camera.

I present some of my first shots with new setup. Conditions are poor so it's not so good yet but still great in comparison to smaller LS60. I was usually taking about 1500-3000 frames in one avi file with LS60. Photos below are stacked from 100-150 frames only. When I saw hole in clouds I had no time to put precisely the mount on north posision. So Sun was getting out of field of view quickly. Next time I will get it better aligned

Very nice images Pablito!
Maybe you could try to change the levels in the second image for more contrast?

Ok, I have new and better version. The last one was not sharp, indeed

Hi,

Due to my work, I had no much time recently for solar imaging but it was worth waiting

Take a look

One more thing. I doublestacked Lunt100 using Coronado SM90 filter and it works great. Views are awesome!
