Summary of Can a telescope be too big?

00:00:00 - 00:20:00

The speaker in the video discusses how a telescope can be too big, and how this affects the quality of the images that can be captured. He explains that environmental conditions can be a problem, and that astronomical seeing can be a problem too. He demonstrates how a telescope can be too big, explaining that with the optional reducer, the native resolution of the telescope decreases to F7.7.

• 00:00:00 The reviewer discusses the reasons why a beginner might switch to a smaller telescope after getting good results with a bigger telescope. He goes on to say that it is harder to get everything right with a bigger telescope, and that this is one of the reasons why beginners switch to smaller telescopes. He also mentions that environmental conditions can be a problem, and that astronomical seeing can be a problem too.
• 00:05:00 The reviewer tests a telescope and finds that it is limiting in detail due to the poor seeing conditions. He talks about how to improve pictures with tinkering, and how the telescope performed optically. One downside is that the telescope did not come with a rotator.
• 00:10:00 The speaker demonstrates how a telescope can be too big, explaining that with the optional reducer, the native resolution of the telescope decreases to F7.7. There is more vignetting or fault light fall off in the corners due to the adapter stack, but with flats, the issue goes away. Lastly, the speaker demonstrates how a different field of view can affect the sharpness of stars in the corners, and how this can be useful for testing a telescope and camera system.
• 00:15:00 The narrator explains that a telescope can be too big if it has a bad back focus distance and that he fixed the problem by adding a one millimeter spacer. He then compares the results of his fixed telescope to the first night's results, which show that he has improved the back focus distance and corners.
• 00:20:00 The author of the video discusses the benefits of joining a Patreon campaign for Nebula Photos, a photography blog. He also discusses how a telescope can be too big for some people, and how a refractor can be a good challenge for beginners.
