Beneath an infinite sky, my cares & worries shrink to nothing.

The Heart & Soul Nebulae captured using a 135mm lens at f/2. #astrophotography

Captured using a 135mm lens @ f/2

My first #astrophotography capture of 2025, following a two-month hiatus due to weather. This image showcases two of my favourite deep-sky winter targets within the Orion constellation. Total exposure of 3 hours. Processed in Pixinsight.

My most detailed rendition of the Pleiades (M45) to date, captured over 11 hours of exposure. Intriguingly, the Seven Sisters have been featured in ancient myths & artifacts across cultures, including by the Navajo, Hopi, Greeks, & Sumerians. #astrophotography

My best capture so far of Comet C/2023 A3 (Tsuchinshan-ATLAS). Clear imaging has been challenging due to obstructions along my western horizon. This image is composed of 20 tracked exposures of 30 seconds each, taken at a focal length of 250mm. #astrophotography

Last night’s aurora borealis captured from our backyard in Naperville, Illinois. Each frame was taken with a 10-second exposure, using a 14mm lens at f/2.8 on our full-frame Canon EOS RP camera #astrophotography

A false-colour inverted image of today’s Sun, composed from 4,000 stacked exposures captured at 420mm focal length. Let’s hope for an Aurora Borealis tonight! #astrophotography

Immersed in a stellar sea, the Dumbbell Nebula (M27) glowed softly in the constellation Vulpecula last night. Total integration time of 3 hours. Processed in Pixinsight. #astrophotography

The Soul Nebula (IC1848) from a few nights ago. Total integration time of 4 hours. Processed in Pixinsight. #astrophotography

Last night’s Saturn at opposition 🪐 This image is a composite of the top 30% of 3,000 frames, captured at a focal length of 2,032mm under less-than-ideal seeing conditions. #astrophotography

The Pleiades (M45) revealed themselves through a 250mm f/4.9 lens, though fleetingly, as thin clouds limited the frames. Total integration time of 2.5 hours. Processed in Pixinsight. #astrophotography

A composite shot of tonight’s Blue, Full & Super #Moon. Captured using a Canon EOS RP paired with an EF-S55-250mm f/4-5.6 Iens. #astrophotography

My first attempt at imaging the Andromeda Galaxy (M31) this season, under less-than-ideal conditions. Total integration time of 3 hours. Processed in Pixinsight. #astrophotography

Last night's Trifid Nebula (M20) to commemorate my daughter's birthday weekend! Total integration time of 2.5 hours. Processed in Pixinsight. #astrophotography

Last night’s Wizard Nebula (NGC 7380) captured using narrowband filters. 🧙 Total integration time of 2.5 hours. Processed in Pixinsight. #astrophotography

The Pinwheel Galaxy (M101) from two weeks ago, captured using our 130mm refractor at f/7.7. Total integration time of 4 hours.

A meteor amongst the star trails captured from our Bortle 7 backyard ☄️ #astrophotography

The Bubble Nebula (NGC 7635) from two nights ago, imaged in broadband colours amid thin clouds. Total integration time of 3 hours. #astrophotography

Last night's Needle Galaxy (NGC4565), captured on a moonlit night. Total integration time of 4.5 hours. Processed in Pixinsight. #astrophotography

This morning’s Sun featuring giant sunspot group AR 3664 & several large (!) prominences. Stacked the best 50% of 13,815 frames captured using our Lunt 60mm double-stacked telescope to produce this composite image. Fingers crossed for clear skies & another Aurora spectacle tonight! #astrophotography

The iconic Pillars of Creation (M16) captured last night using a monochrome camera & narrowband filters. Total integration time of 2.5 hours. Processed in Pixinsight. #astrophotography

Galaxies galore in the constellation Virgo! Total integration time of 4 hours. #astrophotography

A time-lapse of yesterday’s total solar eclipse from Aurora, Ohio. Captured using our full-frame Canon EOS RP camera, paired with a Samyang 14mm ultra wide-angle lens. #astrophotography

A cropped image of the Triangulum Galaxy (M33) captured at 250m focal length (f/4.9) from our Bortle 7 backyard. Total integration time of 3 hours. Processed in Pixinsight. #astrophotography

Barred spiral galaxy M109 & its neighbours, imaged using a 130mm refractor under suburban skies. Total integration time of 5 hours. #astrophotography

I use the app Polar Scope Alignment Pro on my phone, which I attach to a vixen dovetail affixed to the mount!

Second day of field testing for Totality - the solar autoguider works like a charm! Single unedited frame captured using our Lunt 60mm universal telescope with a front-mounted double stack filter, paired with a ZWO ASI 433MM camera #astrophotography

Last night’s Whirlpool Galaxy (M51) - had to throw out a bunch of frames due to high winds. Total exposure time of 3 hours. Processed in Pixinsight. #astrophotography

Last night’s Sombrero Galaxy (M104) - imaged under windy, moonlit conditions. Total integration time of 2 hours. Processed in Pixinsight. #astrophotography
