Astrophotography / IC 443
Last post by JohnH - Mar 21, 2025, 16:32:24
(For some reason I cannot link to the TIFF file uploaded on Astrobin)
For this image I used HaO as the Luminance layer. The very bright star upper right is "Propus" a variable red giant double star ands played havoc with that part of the image.
Data:
Location - Bromley (Bortle 7) Dates - 3rd, 4th and 20th March 2025
Telescope - Sharpstar 15028 HNT (150mm f2.8)
Camera - ZWO ASI1600MM Pro
Control - ZWO ASIAir Pro
Mount - iOptron CEM 25P
Processing - Pixinsight and Affinity Photo 2
R: 60sec x 90
G: 60sec x 60
B: 60sec x 75
Ha: 360sec x 15
HaO: 240sec x 28 (12 additional frames lost to cloud cover)
Total Image time: 7hrs 7mins.

Hi Carole,
It's my third attempt at imaging M81/82. I have added some more data to an image that I put on WhatsApp and reprocessed it. It is probably because my setup uses "plate solving" to locate targets and so ends up with similar FOVs if I repeat a target.

In the Media... / Crew-9 splashes down while NAS...
Last post by Rick - Mar 19, 2025, 14:28:10Crew-9 splashes down while NASA floats along with Trump and Musk nonsense
Elements within the US space agency have elected to toe the party line
The Crew-9 mission has safely returned to Earth, marking the end of Suni Williams and Butch Wilmore's extended time in space and possibly NASA's bipartisan leanings.
NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore, and Roscosmos cosmonaut Aleksandr Gorbunov successfully splashed down off the coast of Florida last night, concluding a 286-day stint in space for Williams and Wilmore.
The duo arrived at the International Space Station (ISS) on June 6, 2024, on the first crewed test flight of the Boeing Starliner spacecraft, but after issues with the Calamity Capsule, mission management elected to return the capsule to Earth empty, and have the pair become part of Crew-9.

In the Media... / Webb telescope directly observ...
Last post by Rick - Mar 19, 2025, 13:58:06Webb telescope directly observes exoplanet CO2 for first time
The James Webb Space Telescope has directly observed the key chemical of carbon dioxide in planets outside of our solar system for the first time, scientists announced.
The gas giants are not capable of hosting extraterrestrial life but do offer clues in a lingering mystery about how distant planets form, according to a study in The Astrophysical Journal.
The HR 8799 system, 130 light years from Earth, is only 30 million years old - just a baby compared to our solar system's 4.6 billion years.
A US-led team of researchers used Webb to directly detect carbon dioxide in the atmosphere of all four of the system's known planets, according to the study.

It is clearly Bode season. This is my final processing (probably) of M81/82 collected 22nd Feb to 2nd March. [he background might be too dark though]
Location: Bromley (Bortle 7)
L comprises HaO and a contribution from RGB
Chrom comprises HaRGB
Total imaging time: 7 hours
Sharpstar 15028 HNT
ZWO ASI1600MM Pro at 10C
iOptron CEM 25P
ZWO HaO, Ha, R, G and B filters
ZWO ASIAir Pro
Processed in Pixinsight, finished in Affinity Photo 2
