Solar granulation and Ca-H with solar newtonian - June 12
An image of the solar granulation taken this morning in fine seeing with a small 130mm Skywatcher solar newtonian, Baader K-filter and 5x Powermate. With the same instrument I also taken a couple of images with a Daystar Calcium-H device, some bright details close to the limbs.

Excellent seeing for 130mm of aperture.

These really are quite nice images! I'm assuming the mirror is still coated?

Thanks to all for your appreciation.
@Mark: I have uncoated the primary mirror only and left the secondary untouched. Observing in WL requires about the same filtering of a Herschel prism.
Best,

Fantastic work. Can you tell us what kind f setup have you used? Primary mirror has ERF coating?

no ERF, just a common parabolic mirror with its coating removed.sulcis2000 wrote: ↑Tue Jun 13, 2017 11:53 amFantastic work. Can you tell us what kind f setup have you used? Primary mirror has ERF coating?

Re: Solar granulation and Ca-H with solar newtonian - June 12
Wow, really awesome granulation for a 130mm!
I can't get convection cells that size with my 120mm refractor with a 3x barlow & continuum filter.
Very best,
