The Sun - 12th Jul 2020

Mixture of imaging and visual today. My first opportunity to image with the Quark attached to the Evostar but I also spent a lot of the session just experimenting with the config; barlows, aperture masks, quark settings, flats, etc. All the images below were taken with the aperture stopped down to 100mm and a 1.5x barlow in place. This seemed to give reasonable balance between contrast and focal length. 

 

 

 

 

Looks like I need to order a tilt adaptor to deal with the Newtons Rings, not unexpected.

Ca-K is much simpler.....

Nothing going on in WL today so rather than grab a full disk I just went for some granulation.

Good stuff.

Seeing from here was not great.

after what ive been seeing in my calcium filter, i doubt i will ever go back to h-alpha   

 

i just picked up a 3.5x siebert optics telecentric to get the most out of my setup, hopefully it works out.  

 

Great images btw,  the convection cells are awesome and i see you grabbed the Calcium spicule layer.   Very few are imaging that and you should be happy that it comes in for you,  most lunt filters dont show it.

Excellent set of images
