The Flaming Star and Tadpole Nebulae....1500 light years away, in Auriga.

This is 47hrs of narrowband SHO data, captured with FLT91 scope and 2600MM Pro. Hope you enjoy!! #Astrophotography

going to cheer myself up by participating in #photomonday and share a few snaps that were firsts for me in my amateur journey.

the 2 attempts at #astrophotography were taken last year during our #leafpeeping camping trip, and the first time i was able to capture the #milkyway

the other is the first time i was able to get #lightning when we were at #devilstower earlier this year and is a few different shots stacked together.

nothing special, but man was i excited both of those nights

An old favourite game! PACMAN NGC281 #Astrodon #astrophoto #astrophotography #astronomy

Need to get better at masking to really pop the details in Horsehead, but got some more good data last night.

The Eridanus Loop (Sh2-245), the lesser-imaged half of the Orion-Eridanus Superbubble. The more commonly imaged half is the much brighter Barnard's Loop in Orion. #astrophotography

The Rosette Nebula 🌹
Taken with a modified DSLR and a small telescope from my rainy UK garden in Suffolk.

Eclipse of the Earth by the Moon! NASA's #Artemis1 got this view before this morning's extremely close (130 km/81 miles) flight above the lunar surface to reshape its orbit. https://blogs.nasa.gov/artemis/2022/11/21/orion-successfully-completes-lunar-flyby-re-acquires-signal-with-earth/ #space #moon #nasa

This was the first image of the #Earth 🌍 taken from the #NASA #Orion spacecraft as it rounded the limb of the #Moon 🌖 and was reacquired by the #DSN. Every human is in this photograph. With the population of the planet having just crossed the 8 billion mark, https://www.worldometers.info/world-population/, this is the biggest family photograph ever taken! #Artemis #Artemis1

The #Earth as seen by the #Apollo 10 (left, in1969) and #Artemis 1 (right, in 2022) missions.

Those 2 pictures are taken 53 years apart, with #spacecraft on their journey towards the #Moon.

In 1969, 3.6 billion people are on the #picture (minus the 3 #astronauts)
In 2022, 8 billion people are on the #picture

I've been working on a Curiosity rover wheel replica lately! It's about 1/5th scale and trying to stay as authentic to the original as possible (which makes some interesting machining challenges at such a small size).

The wheel's skin is just 1mm thick, and the grousers are ~2mm tall. The original wheel skin was just 0.75mm even though the wheels were nearly 500mm in diameter! The originals were machined from a single billet of aluminum and anodized black.

I can remember being a 12 year old kid looking at the photos of space in Sky & Telescope Magazine - amazed at the wonders people recorded. It just seems surreal to me that others are now staring at my photo of M31, The Andromeda Galaxy, in the December 2022 issue. Such an honor. #astrophotography #astrophoto #astronomy #space #photography

Why don't we start the day with an old friend? These are two images from #NeowiseComet back from 2020. Feels like such a long time ago. I had about two hours before the sun was about to rise, I almost ran to that small hill and set up the DSLR and tripod.

My best two images from Octobers partial solar eclipse.

I'm super proud of these considering I took them on my phone!! I used solar glasses over my phone camera, because I'm very hi-tech.😂

Did you manage to see the eclipse?

Please never look at the sun without proper eye protection!

And here's Pleiades, lots of noise in this one that I struggled to remove, I think there was a lot of light pollution. I might try a lower ISO now that I have a tracker and can do longer exposures.

A road less traveled .... this is "Little Rosette" nebula (Sh2-170) which is also the "dot" in the "Question Mark" nebula. Located between Cassiopeia and Cepheus.

Captured with a 6" refractor, one-shot-colour camera (QHY128C) & dual-narrowband filter (L-Extreme). From my Bortle 5/6 light polluted back yard 😦

233x5m exposures over 8 nights in October (it was a good #astrophotography month!).

I think there is room for improvement if I work on my processing skills.

Cleaned up a lot of the banding issues, thanks to

#Introduction time! 👋 I am an #engineering #professor at Queen's University in Kingston, #Canada. My expertise is in field and mobile #robotics. I have a newish interest in applications of #machinelearning to #control and #navigation problems. Previously worked as an #engineer at #space #robotics firm MDA. Also currently serve as Director at the Ingenuity Labs Research Institute. My #math #teacher wife and I have three #kids and we enjoy #golf.

How freakin' cool. A #meteor was picked up by EarthCam's CN Tower webcam in #Toronto.

Several hours before it hit, David Rankin at NASA's Catalina Sky Survey spotted the object, and Michael Busch started a thread: https://mastodon.online/@michael_w_busch/109368965024525842.

From last night. NGC 1499 in narrowband using a RedCat51 and QHY268m.2 styles of SHO processing (2nd if using the ForaxX_SHO #astronomy #astrophotography

I suppose it’s time for an #introduction. Not much going on here. I’m a native #NewYorker who found his way to an undergrad #Physics degree, thus the handle. I was in Marketing, then had a second career for 18 years as a #HighSchool #PhysicsTeacher, but have found my way back to my first career.

In my free time, I like to point my camera mostly at the sky, dabbling in #Astrophotography but also enjoy a good rocket launch. Occasionally I get a lucky shot, which I’ll post here.

Nothing special.
