ABOUT US

We are a collaboration of amateur astronomers (members from 🇩🇪, 🇮🇳, 🇺🇸,
🇦🇹) focused on detecting and recovering asteroids, submitting our observations
to the IAU's Minor Planet Center (MPC).
We are using Tycho's GPU-accelerated synthetic tracking capability to detect
even faint objects which are not visually detectable in individual exposures.

Observatory code: X09
Telescope location: DeepSkyChile
Telescope system: PlaneWave CDK400 (CDK17 + L500 mount)
Camera: QYHCCD QHY600PH-M

If you like the idea of applying computational and brain power to finding new
asteroids and refining existing orbits, helping scientists along the way, feel
free to join us!

A SPACE STATION & TOOLBAG PHOTOSHOOT

Is anyone missing this toolbag?

Well, yes, International Space Station (ISS) astronauts do since accidentally
letting it fall into space on Nov. 1 2023. Since then it's been orbiting Earth
all by itself. Resident satellite hunter Felix Schöfbänker (SomeAstroStuff)
managed to take a video of it, along with some other objects:

toolbag was captured. Click on the image to see a higher resolution version
Another pass of the ISS, one day later, passing almost directly overhead at a
87° peak. This is also noticable because of how much more detail becomes visible
even without any sharpening. The change in brightness in between is because i
changed the exposure time during the capture. Click on the image to see a higher

A NICE NEW NEBULA PICTURE, AND A REPROCESSED OLD ONE

These are RGB pictures of GUM 15 and the Pencil nebula. Taken with the CDK-17
F/6.8 and a QHY600.



---------- ---------- ---------- 
GUM 15 integration time: 
R = 1h50min
G = 1h45min
B = 1h50min
all 300sec subframes
No calibration frames used
Taken on 6. February 2024
High clouds appeared when taking the B channel, so this messed it up a fair amount by causing the image to lose contrast and become diffuse.
Fairly cropped in from the full FOV. (because of the HC and lack of calibration frames)
---------- ---------- ---------- 
Pencil nebula:
total/per filter integration time unknown due to lack of documentation, subframes 180sec.
The B channel had some calibration issues, so this caused the slight artefacts. 
Fairly cropped in from the full FOV.

Both pictures edited with PixInsight.

A PROVISIONAL SECOND ASTEROID DISCOVERY: 2023 ML16

News from our discoverer, Divye:


This one is special, because I had detected and submitted the astrometric
observations back on June 25, 2023 (temporarily designating it as TR0055), and
had forgotten all about it after having failed to recover it due to the bad
weather at Chile. 😊

Back then, the Minor Planet Center (MPC) had not yet provided our telescope with
a dedicated observatory code, and I was submitting observations as a Roving
Observer. It was thereafter recovered by Pan-STARRS, Haleakala on August 20,
September 4 & 16, 2023 and the MPC linked it back to my observations (the first
observations in its current opposition) vide M.P.S. 1973754.

The object was recognized as a newly-discovered main-belt asteroid and
provisionally designated as 2023 ML16. Links to NASA's JPL and MPC databases
below:

2023 ML16 on the Minor Planet Center (MPC) website

Since this one was linked to observations from back in 2008, it has a pretty
stable orbit by now. Interestingly, the orbit suggests it may belong to the Eos
family of asteroids: Eos family on Wikipedia
