  • Powering laptop: for extended imaging runs, some type of inverter and 12v supply will be needed. Most laptops, when fully charged will last for at least 2 hours. Most imaging runs only last a few minutes but, when you find out how much fun this can be, that 2 hours will be gone fast, so plan accordingly
  • I overhear Dennis Plews mention that he just bought ToUcam for $40 – ebay?
  • Purchased at Wal-Mart 4 years ago $75
  • Plastic bezel just unsnapped and off it came. Lens just unscrewed.
  • Adirondack Astronomy - $55
  • Color Filters are one of the most popular on every one's astronomy list. They serve both photographic and visual purposes and can often be combined "stacked" with other filters to produce higher results. While several pages could be dedicated to color filter uses, let's take just a moment to look at some high "lights"! Light yellow is often used for revealing planetary and lunar details as well as improving comets. Yellow-Green is primarily used for lunar and planetary details. Medium yellow is superb for bright planet and cometary details, while the darker yellow will also assist in daytime planet viewing. Orange enhances planetary details and works well with solar filters. Light red helps with lunar and planetary details, as well as daytime planet viewing. Red is a must for planetary and lunar details and also improves black and white photography. Deep blue serves towards some lunar and planetary details and improves bright comet tails. Violet is a must for observing Venus phases and details - as well as some other planetary details. Light green enhances lunar features and improves some planetary details. Green performs excellently on the Moon, Venus and helps with some other bright planetary details. Medium Blue is a filter necessity for lunar details, cometary details, and planetary details. Light blue can also be used to help reduced fringing. All Color Filters have a wratten number which also helps the photographer as well!
  • This program can save your bacon by saving your video in the AVI format
  • Notice “Dust Mote” in crater, kicked tripod leg and sloppy hand controller operation during playback!
  • File had to be broken down into 3 segments of 1000 frames and 1 segment of 600 frames. For this presentation we will be using the third segment of 1000 frames. This was a limitation of the version of Registax I was using. Newer versions of Registax don’t have this limitation!
  • Or don’t put it away and you can go back and take additional images or do observing.
  • We will be using Version 4 of Registax. Current version is V5 but, V6 is currently in Beta.Press the Select button/tab to choose your captured AVI file for processing.
  • Standard Windows file selector box
  • This is frame 1 of 1000. It shows that our AVI has been loaded and Registax is awaiting our commands
  • Step 1 Moved to a frame that is fairly in focus. Step 2 Chose multipoint. Step 3 selected alignment box size and selected features to align to. Step 4 Pressed the Align button. When Registax is finished, Pressed Limit Button
  • Now it’s time to press Optimize & Stack. This will take and optimize our frames and then stack them into one image
  • Registax is on it’s own, stacking our images.
  • Here is our final stacked and optimized image, We will now use the Wavelets sliders to highlight, add contrast and sharpen the image
  • Step 1 uses the most finite adjustments step 2-4 (6) use progressively larger adjustments. Go easy as you move through these.
  • Due to artifacts introduced by processing, we will want to crop the image to get rid of some of the artifacts. Step 1 tell Registax that you want to crop. Step 2 draw your crop box around image that you want. Step 3 Save the image
  • Here’s our final image saved as a JPG file that we can add to a photo album, webpage, whatever!

    • 11. IR Filter
      An IR (Infrared) cutoff filter is needed to prevent “star bloat” or image bleed in the pixels of the webcam.
      Especially needed for refractors because they focus infrared and visible light at different points
      Webcams are very sensitive to UV/IR light

    • 26. How to do it!
      Whistlestop Observatory - Chip Frappier
      We’ve gathered our Equipment and all our Software
    • 27. The Process
      Hang on tight cause here we go
      Whistlestop Observatory - Chip Frappier
    • 28. Whistlestop Observatory - Chip Frappier
      Set up telescope
      Do alignment
      Focus on the Moon
      Pick a Target along or near
      the Terminator
      Insert Webcam, Start Software
      Refocus on target
      Capture images
      Process captured images
    • 29. Pick Target Along or near Terminator

    • 32. Whistlestop Observatory - Chip Frappier
      Previous capture lasted for only 120 seconds
      Captured as an AVI file by Iccapture through a Imaging Source DMK21AF04-AS camera
      At a frame rate of 60fps
      That’s 3600 individual pictures that were taken
      Out of those 3600, 100-200 will be clear enough to use
      At this point we are done with our imaging or
      We can image other features on the moon or proceed on to the processing of our captured files
    • 33. Whistlestop Observatory - Chip Frappier
      Okay, we can now put the Telescope and other equipment away and move inside where it is warm and we have plenty of light
    • 34. Image Processing
      We will use our software named Registax for the processing of our AVI image file
      Whistlestop Observatory - Chip Frappier
