Details:
I 'd like to share with the "sunspot Community chasers" my trials with different filters this morning in white light. All of the 4 images were taken with a Takahashi Mewlon 250 (not perfectly collimated!) fitted with an Astrosolar ND3.8 and a Basler 1300 camera. Videoes of 3000 frames (each about 40 seconds). The seeing was very good and the turbulence was weak in my spot. In THOSE conditions, I found the advantage to the IR 807, don't you ? Can it be profitable to everyone !
Cheers.
