AI Thread Summary
The discussion focuses on capturing the Mars occultation, with users sharing their imaging setups and techniques. One participant is using a C11 telescope with a 0.33 focal reducer and a ZWO ASI1600 monochrome camera to photograph the event. They plan to capture the "in" and "out" phases of the occultation using different cameras for optimal detail. The imaging process involves stacking thousands of frames to reduce atmospheric distortion, though this can lead to smearing due to the movement of Mars and the Moon. The final image is a composite, combining separately processed frames for clarity and detail.

TL;DR Summary
Observation of the Jan 13, 2025 Mars Occultation
Post your pics of the Mars occultation here!

Currently it's 8:20 EST, about an hour from the occultation. Below is a still of what I'm working on (the gray dot near the right side is Mars):

I'm using my C11, a 0.33 focal reducer and currently using a ZWO ASI1600 monochrome camera. It's the only setup with which I can shoot the entire moon with the C11. I'm going to shoot the "in" with this setup and the "out" at higher magnification and a color camera. The color camera has a much smaller sensor and pixels so it can't image the entire moon even with the focal reducer.

This is a 3,000 frame stack. Seeing isn't very good, so there isn't much detail to be had.

Well this ended up better than expected!

Incredible photo, looks like a composite.

It sort of is. It's not a single frame; to take high-res photos through the atmosphere you take thousands of photos and stack them, which cancels-out the atmospheric distortion. But because the Moon and Mars are moving relative to each other, stacking photos will smear one or the other. So they have to be processed separately and then re-combined, from one or a set of massive video file(s). But it is the same camera, same settings, about the same time, and the separately processed Mars is pasted over a smeared version of itself.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
