| Photos of The Week - January through April, 2016 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 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. |
| 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 Processing: PIPP, AstroStakkert, Registax, PS4 February 28, Canton, Georgia Left: Jupiter, Ganymede, Europa (rising left), Io (and transit shadow). Right: Jupiter, Europa and Io (transit) |
| 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 Capture: Firecapture @ 134 fps, best 40% of 4000 frames for each of L, R, G and B filters (about 1600 stacked frames per filter) 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) |
