Nice limb activity (90 mm)


Recommended Posts

I was hoping for another X-class flare from AR 3007, but only caught some small-scale limb activity above AR 3011. Everything shot with a 90 mm refractor coupled with LS50THa etalon, Blacfkly S (IMX 273), processed with AS!3 and ImPPG.

Very nice images.

Out of interest, when you say you coupled LS50THa etalon with 90mm scope, how did you do it?

Is it F/7 scope and you shortened the tube and fashioned adapter for etalon to be screwed in (soft of PST mod with Lunt internal etalon)?
