halpha sun of August 10th

Post by stef41 » Sat Aug 10, 2019 4:28 pm

Good morning, everyone,

a sun of the day a little more hairy than usual, as well as a micro filament present! :)

to the fs60 with its sm40 double stack, glasspath x1.25, BF10 and zwo178mm around 13h UT

To celebrate the presence of these two beautiful prominences, I tried the barlow on it.
But
1) powermate x2.5, it's a little too much (especially with the ADC in addition which, removes the interference fringes, but adds draft)
2) the zwo178mm still makes me a frame and I can't apply a flat on this type of image

I'm going to have to pull out my dmk41 and find a smaller barlow (I have to get my hands on my glasspath x1.7)...

otherwise: with powermate x2.5 and sm40 simple stack, reduced to 75%.

cordially,
