M33, Fall 2024

This is first light with the TS 102SD, native at f/11 but telecompressed to f/6.93.  This is also first light with a Player One Uranus C Pro camera.  I haven't had a camera in a while.  So far, I'm impressed with this one.  This is 41x300s.

Double Cluster - NGC 869 & NGC 884

 

This is 37x300s with the Player One Uranus C Pro through my TS Optics 102SD f/11 and the Astro-Physics Telecompressor (CCDT67), which reduces the scope to eff. f/6.93.  This was taken from my backyard, and my subdivision lately installed new >4k streetlights with no shielding---a disaster for astronomy.  I'm doing my best here and still glad I can do something.

Comet C/2023 A3 (Tsuchinshan–ATLAS), October 13 & 16, 2024

These were taken with the old Canon T3i and a zoom lens on hand, over a drainage pond.  I spotted the comet first in an image taken of the area SkySafari indicated the comet would be found.  I took about 160 images, and these were some of the best.  The camera was stationary on a tripod.  The images would have been much better if the camera were tracking.

This one was a phone shot with the Pixel 4 XL, taken on Wednesday Oct. 16 when I was showing the comet to some friends:

M8, the Lagoon Nebula (2024)

 

This is data from ATEO-1 at Starbase.  ATEO-1 is a 16" f/3.75 Dream Aerospace Systems astrograph, one of the premier imaging telescopes available.  This is just 170 minutes of data, but it is clean and deep and fun to work with.  This image is Ha-OIII-SII in a modified Hubble palette.

Mineral Moon, New Telescope

This is first light with the TS 102SD f/11.  Thus far, the scope has impressed.  I hope to do a longer review later.  This is the nearly full moon of April 22, 2024, shot with the Canon T3i at 1/4,000 of a second. The image is color-enhanced to show that different parts of our moon reflect light differently. The colors differ because the minerals that make up the moon's surface differ from place to place.

Eclipse of April 2024—Recorded by NOAA Weather Satellites

On eclipse day, I was exhausted from a long trip, so I stayed in Houston and went to work.  The whole area was clouded out.  However, live feeds of the event and NOAA satellite data were quite the show! Three cheers for NOAA satellites! Here's what I saw over Texas, the US, and Earth. Note that the center of the shadow, the umbra, is darker than the borders, the penumbra.

 

 

 

M81 & M82 (May 2023)

 

This is a data set from OMI Astro.  It's 11.4 hours of R-Ha/G/B.  This is actually one of my favorite parts of the sky.  These two galaxies are very bright.  In my 10", they look like a whirlpool and a wave, about of equal size.  I can almost squeeze them in the same field of view with the eyepieces I use.  It's quite a sight to come across these very bright objects.  In the telescope view, they have no color at all because they are so dim, even though they are about as bright as galaxies appear at the eyepiece.  Leave it to the camera to pick up colors. OMI collected the data with a Takahashi TOA 150.  I was hoping to work with data collected with a refractor, and that's a good one.
