I'm switching from using a 1.25 inch LPR (Light Pollution Reduction) filter to a 2 inch filter because I believe it will make my equipment more secure when it comes to mounting my DSLR (with T-Ring) and CCD cameras onto my Schmidt–Cassegrain telescope. I may also get a 2" CLS filter in the near future, just to compare it to my LPR. The astrophotography equipment used in the video are listed below: Optolong L-Pro Filter – 2" Mounted
2" – T2 Adapter Thread Outside
2" SCT adapter I used the NexStar 8SE telescope in this demonstration, but this system should work with any of the following Celestron telescopes: C5, C6, C8, C9¼ and C11 telescopes. When using a f/6.3 focal reducer, the reducer would go on first followed by the 2 inch filter. Chuck’s Astrophotography For people interested in Astronomy and Astrophotography.

A United Launch Alliance Atlas V rocket is set for a U.S. West Coast launch on Wednesday lifting into orbit a clandestine payload for the National Reconnaissance Office.
Secret Mission with the delivery US Navy satellites.
Atlas V, flying in its basic 401 configuration, is set for liftoff from Space Launch Complex 3E at Vandenberg Air Force Base at 17:50 UTC.
NASA Television provides live coverage of launches
Managers cleared Atlas V to head into final launch preparations on Monday in a clean Launch Readiness Review and meteorologists have issued a 90% chance of favorable conditions during the day’s classified launch window that closes no later than 18:30 UTC.
Atlas V NROL-79 Mission Profile
Following up on Wednesday’s mission will be a Delta IV launch on March 8 from Cape Canaveral lifting the ninth satellite for the U.S. Military’s Wideband Global Satcom communications constellation and a March 19 launch of Atlas V will loft the Cygnus OA-7 mission to resupply the International Space Station.

he pair of images in this animation shows effects of one Martian day of wind blowing sand underneath NASA’s Curiosity Mars rover on a non-driving day for the rover. Each image was taken just after sundown by the rover’s downward-looking Mars Descent Imager (MARDI). The area of ground shown in the images spans about 3 feet (about 1 meter) left-to-right.
The first image was taken on Jan. 23, 2017, during the 1,587th Martian day, or sol, of Curiosity’s work on Mars. Figure 1 above is the image with a scale bar in centimeters. The second was taken on Jan. 24, 2017 (Sol 1588). The day-apart images by MARDI were taken as a part of investigation of wind’s effects during Martian summer, the windiest time of year in Gale Crater.
When Curiosity landed inside Gale Crater in August 2012, MARDI recorded the descent from the rover’s point of view. Malin Space Science Systems, San Diego, built and operates MARDI.
NASA’s Jet Propulsion Laboratory, a division of the Caltech in Pasadena, California, manages the Mars Science Laboratory Project for the NASA Science Mission Directorate, Washington, and built the project’s Curiosity rover.
