TOM2019 Questar Egress Sequence as Time-Lapse “Movie” FULL LENGTH

Quick-look movie using the TiO speckle reconstructed data for the Mercury Transit (From The Big Bear Observatory)


Images by Glenn Schneider with a Questar and a Williams College Questar filter in collaboration with Jay Pasachoff and Bill Sheehan. Quick first reduction. At Big Bear Solar Observatory in a dome alongside the dome of its 1.6-m Goode Solar Telescope. The Questar telescope is 3.5 inch (0.089 meters) diameter aperture. The effective focal length is 1422 mm (f/16).  The Questar full-aperture solar filter has optical density 4.8. The camera used was a Nikon D800.  Images were taken at 1/1600 s at ISO 500. The full disk image was taken at C3 minus 30 seconds.
The egress limb-crossing image sequence is at a 15 second cadence.

Black drop: From the Big Bear Solar Observatory –

The camera used for our Broad Band Imager uses a PCO-2000 high speed CCD normally imaging through a TiO filter (10A FWHM centered at 7057A).

Raw frame #415 that shows the moment of 3rd contact. The time stamp on the frame is 18:02:55.


Black-drop image by Alfredo Vidal <[email protected]> Solar Activity Picture of the Day for November 14th, 2019. “The world wide home of active solar imagers”

Celestron C11 Edge HD F:10 telescope working at primary focus with a Baader ND-5.0 Solar Screen Filter Mylar sheet + ZWO ASI290MM monochrome camera with Continuum Baader green filter from the terrace of his home in Hospitalet del Llobregat (Barcelona/Spain).
The resulting video record was made in black and white. Subsequently and with the use of the public domain program: VirtualDubMod  uses various VDF digital filters (plugins) provided by the program to give: false color, improve contrast, noise removal, etc., in order to obtain a single frame in which you can interpret the “black drop.”
