Intes M715 first light in Hα

Post by GreatAttractor »

On Wednesday I tested the Intes M715+Aries ERF+Lunt 50 etalon combination — and finally got good high-resolution Hα material. Even though the seeing wasn't exceptional (I'll post SSM readings later), the results beat anything I got out of the RC8 hands down. It seems I was having internal heating issues there after all, and Mak's corrector probably absorbs/reflects much of the IR passed by the ERF (before it gets focused on mirror bafles etc.).

Of course, it's not an optimal setup: feeding an f/15 (instead of f/7-8) beam to the etalon assembly means a smaller angular size of the sweet spot; still, it sufficed for my targets.

Everything captured with Blackfly S (IMX 273), processed in AS!3 and ImPPG. Note: right-click a video for looping and fullscreen options.

Great images! I also have a 7” Intes Rumak at f/10 and it performs very well on the Sun in H-Alpha. I’m going to prepare an astrosolar film filter for the continum and calcium light. I think you will enjoy your setup 😉
