  1. updated to 85 frames, more frames still prcocessing. 20 minutes of time represented here. 127mm x 1200mm + meade 2x shorty.
  2. I am thankful for the unseasonable weather and imaging i have getting. This is shot with my super high speed camera. If you pay attention to the sunspot penumbra you will see a little worm like appendage retreating into its core. Also notice the pulsating center. Captured at 500fps. and the rest of the film captures that larger fibril get sucked back down the drain. .
  3. Hello I was able to enjoy a few minutes of very good conditions to make Theophilus After regular degradation forced me to work more and more in infrared until abandonment. Theophilus shows the capacities of a large diameter in good condition very rarely available. The following images are close-ups of craters almost never photographed so precisely by amateurs except Endymion. Most of their images were taken by satellites. The favorable libration made them most accessible. I hope you will like. Clear skies. Luc CATHALA
  4. I have the 11x70 model which has preferred Baush and Lomb body. Excellent optics and eye relief. Are the 20x100s as good optically, and do they have the same high eye relief?
  5. Hello Despite just Medium turbulent conditions I could start doing tests with the new QHY5-III178mm and my 625 mm. The number of pixels available can cover a large lunar surface relative to my old camera and the small size of its pixels allows me to strong magnifications. When the weather will be correct it should be fantastic. Some images for you. Clear skies. Luc
  6. Hi, I have struggled with the Drizzle technique many years but had always problem to see any difference when taking images with my teleskop, shorter focal lenses has worked good. Now with faster computer, Windows10 64-bit and new updated software it works as I expected it from the beginning. The idea come already when I took my first digital astrophoto, the comet Hyakutake 1996. I read about NASA and how they use Drizzling on Hubble images to increase the undersampled images from it. I have documented my workflow here and a first test with the Globular Cluster M13 as a test object. http://www.astrofriend.eu/astronomy/projects/project-get-higher-resolution/01-get-higher-resolution-introduction.html My astrophotos with the telescope are taken from the balcony and never of very high quality, but this time it worked. /Lars
  7. Hi, included some images of April 12th. One image of Vallis Alpes, witht he large craters Arsitoteles and Eudoxus. Rima Hyginus, with lower in the image Triesnecker and Rimae Triesneckes to the right of it. The Apennines. A large mountain range. This is a two panel mosaic. and last byt not least a high res image of the lunar terminator from the Large crater Ptolemaeus all the way to the South pole. All images made using CFF CC300 f/20 and asi 174MM at prime focus. An Astronomik proplanet 807 filter was used to stabilize seeing. Enjoy the images, and feel free to share your toughts, comments etc. All images are also visible on my Astrobin page.
  8. Second time I undertake this kind of endeavour. Many many movies were shot. Over 300Gb of data. Stitching was done by hand. in adobe Photoshop. Equipment used: CFF 300f//20 cassegrain ASI174MM with Astronomik proplanet807 processing using Autostakkert, lynkeos and adobe photoshop. Image is a wee bit too large to add to post direclty. hence just the link. https://astrob.in/400728/0/ Make sure to check out at full res. enjoy. Wouter.
  9. Hello Bad conditions on France but I could still do some pictures that day. I used my 625mm, barlow 3, IR 685 filter and the excellent QHY5-III 178MM. Two versions of each image one at 70% and at 100%. Clear skies. Luc CATHALA Messier and Messier A I have not found better by an amateur on the web.
  10. hello Unable to make films because turbulence so I take on old movies on my hard drive. A mosaic made with images of 2012 I reprocessed. A red filter causes kickback in the shadows, but the image quality allows a presentation to 150%. I hope you like the walk. Smallest details in Clavius between 550 and 600 m. Click on the image for 100%. Good day. Luc CATHALA
