Patrick Shank - caught deleting video comments that expose flat Earth as a delusion - shows out of focus images of stars and tries to pass them off as real - what Bollocks!
Dear Patrick Shank,
Are you lying in your videos purposely or is it that you are just ignorant?
Your following star images are all out-of-focus monstrosities. And then when we told you so, you deleted our comment so your channel visitors would not see your deception.
Shame on you FRAUD!
Get a decent telescope and you will see what they really look like.

What do out-of-focus star images look like...
To test the telescope, I attached a Nikon Coolpix 4500 camera to a 12.5 mm Plossl eyepiece and took images of a bright star on both sides of best focus. The camera lens was zoomed to its maximum focal length (32 mm), but digital zoom was not used. The camera focus was fixed at infinity. Images were taken in `Multi-Shot' mode; when the shutter was released, the camera took 16 frames, each 568x426 pixels, at a rate of about 2 frames per second. Exposure times were 1/15 sec at EI 800. In-camera image processing - contrast adjustment, image sharpening, and noise reduction - were all disabled; images were recorded using `FINE' image quality.
The images above were obtained on April 6, 2004 at about 20:30. I used Pollux (beta Gem), magnitude 1.2, which was nearly overhead and therefore provided the best available seeing; nonetheless, as these montages show, the out-of-focus images of the star varied considerably from one moment to the next. Each frame was processed by computing the centroid of all pixels with intensities above 0.25 of the maximum possible value and extracting a 64x64 pixel region centered on this position; these smaller images were then reassembled to produce the final montages.
To estimate the image scale, I measured the dinural motion of Pollux between the first and last exposures; the star moved about 109 pixels during each 7.5 sec sequence. Pollux is at dec = 28.0°, so its apparent motion is cos(28.0°) × 15 "/sec = 13.24 "/sec. The image scale is thus 0.91 "/pixel, and the out-of-focus images of the star are ~30 " in diameter. This implies that these images were taken at about 0.8 mm on eiter side of the best focus, corresponding to a focusing aberration of 8 wavelengths.
On the whole, there seems to be a systematic difference between the inside-focus and outside-focus images. The outside-focus images exhibit bright, rather well-defined outer rings, with lower intensity levels within. The inside-focus images are generally brighter toward their centers, and appear wispy or hairy around their peripheries. These symptoms suggest the mirror has a turned-down edge.
