The Reveal Focus Filter

Real Results from the Reveal Focus Filter

This is part 2 of the story of the how the Milky Way Revealer works. In Part 1 we learned how the Revealer works and how accurately you can focus in mere seconds. If you haven’t see the first page, much of this may not make sense. Please click here to visit it first.


After our focusing session of Part One, I took this image as part of a 48 image panorama.  So let’s see what the results look like after our 30 second focusing session. These are straight out of the camera with only minor color adjustment and enabling a lens profile. This is the frame at full size without cropping. I have rescaled the images to keep load times to a minimum.

Take a look at the full frame carefully. Fantastic result, some minor coma or vignetting in the corners but the focus on the stars is tight. How tight you ask? Let us fly deep into this image and find out just how tight it really is. We are going to slowly zoom in on the area enclosed in the square of the below to see the results.

The focus looks really tight and that gives us a nice result for a single 50mm image.


Let’s crop off a bit of the picture to move in. Then I’ll label some of the objects so you can see where the zoom will lead us. We are headed to the North American and the Pelican Nebulas. See how small they are in an already cropped image.


Here’s a very nice move in on the data and at this scale, it has a great look.


Another move in and the stars are still tight and not bloated.


So here is a 200% zoom of the raw data. That cropped result won’t win you any NASA APODs but its nothing to be ashamed of and a fantastic result for even a reasonable telescope. All in a minute of focus and exposure. Pretty neat deal in my book.

Here is the location of the image in a panorama. Look how small and tight the stars are in the big picture!
