Imaging results with ZWO's asi224mc and asi174mm USB 3.0 CMOS
cameras.   Test of the DayStar Quark Ha solar filter.
Testing various setups with two new ZWO cameras, a new Hutech modified Canon 6D and the DayStar Quark Ha solar
eyepiece/filter/barlow unit.  Details coming as I post over the next week or so.
Solar imaging - Explore Scientific ED80 Triplet f6, fl480mm, Quark unit (with 4.3x barlow) and ZWO asi174mm
cooled USB3.0 camera:

Note that the Quark unit shows significant Newtonian rings and vertical banding that one purportedly has to either calibrate with flats to eliminate or
use a tilting/collimation unit.  I will try the flat method and I hope it works.  Bottom line though, absent the problem with imaging (hopefully
surmountable), the Quark unit is a fantastic way to get into solar viewing/images without spending $6+K and, with the proper ERF (Energy
Rejection Filter), is portable between scopes.  Help from Kevin McArthur on the setup and imaging.
Planetary and Lunar test - C11" Edge HD with 2x barlow @ f20, fl5600mm and ZWO asi224mc USB3.0 color

Planetary stop motion imaging:
Imaging Setup: C11" Edge HD SCT and Baader VIP modular 2x barlow (combined to FL=5600 mm @ f20)
Camera: ZWO asi224mc USB3.0 camera (.14 arcsec / pixel in this configuration) - captured w/ Firecapture

5 stacked frames - 5.5 minute
intervals
12 stacked frames - various
intervals over one hour
Planetary imaging with ASI 174MM - EP Projection method:
This one didn't come out too bad. I used the Eye Piece Projection method to get more focal length out of the ASI 174MM cooled.  Result as well
as images of the imaging train and the measurements.  April 5, Canton, Georgia

Details on capture: 4/5/16
Camera: ZWO ASI174MM cooled mono video CMOS

EP: Baader Hyperion Click Stop Zoom @ 20mm
Spacing: 90 mm including manual filter wheel
Resultant Focal Length: 9800 mm
Filters:  Baader L,R,G,B
Scope: Celestron C11" Edge HD
Processing: AutoStakkert V2, Registax V6, WINJupos anti-rotation, PS4, PixInsight (only to produce BMP)
