I'm trying out some new imaging gear.

 

For full solar discs, I'm using a Williams Optical WO66ED, 66mm aperture reduced to 32mm, 389mm native focal length reduced to 245mm with 0.63x SCT focal reducer, Quark Chromosphere and 0.5x focal reducer.

For close ups, I'm using an Orion 100mmED f/9 with 900mm native focal length, Quark Chromosphere and 0.5x focal reducer.

Thanks for looking; comments welcome.

 

By the way - the seeing was BAD!  Many images were only 6 frames out of 4,000!

 

Best,

Rick

I think these are your best as well.  I think you could back off the sharpening just a hair, but that's a personal preference.  That first full disk is really nice.

Hey Warren...

"I think these are your best as well."  Thanks.

"I think you could back off the sharpening just a hair, but that's a personal preference."  Yes, I've heard that before... OK.

"That first full disk is really nice."  Hmm, strange because I didn't like it,  preferring the reprocessed version - perhaps over sharpened but far less messy around the perimeter.

 

Thanks for your comments!

 

Best,

Rick

The first disk looks more natural (to me) and the glow around the edge is OK as it shows more structure of the proms.

Yes Mark - the 178MM.  Full disc images are 2080 x 2080 pixels (2.4 microns) on the sensor.

 

Best,

Rick
