The sun, about 30 mins ago. Sunspot region 4060 is super flary (dark patch) in this inverted image. It measures 120,000kms end to end. Captured with the ML Astro SHG700 spectroheliograph, QHY678M and SkyWatcher 82ED, Processed in Jsol’Ex 3 and AS3. #solar #astrophotography #mlastro #shg700 #skywatcher #qhyccd #thesun

This very long photo is the result of the QHY Mini

This very long photo is the result of the QHY Minicam8’s quite long sensor that I decided to leave mostly uncropped! Everyone is looking at these images on their phones these days anyway right? 😆 The Carina nebula is too big to even fit onto the sensor, but looks great even with this modest focal length of the Apertura 75Q Petzval quintuplet telescope. My last shot with my bigger telescope was the keyhole nebula in the centre, but the surrounding area is a southern hemisphere favourite. It’s so bright and so big, it’s almost impossible to get a bad photo.

Keyhole Nebula with Eta Carinae [PUBLIC DOMAIN] 7

Keyhole Nebula with Eta Carinae
[PUBLIC DOMAIN] 7 APR 2025

Can you find God’s middle finger?? :)

My goal for this photo was to resolve Carina’s famous star, Eta Carinae in a way to show its binary shell (Homunculous Nebula) that surrounds the star, but also the hydrogen ring that surround the outburst itself. This is very hard to do since the whole emission is hydrogen and the outer region and the star itself need to be separately exposed. Zoom into the bright star to see what I mean. I have a bit of a behind the scenes about capturing on my YouTube if anyone is interested!

As we finally get back to normal after Cyclone Alfred I just wanted to share this photo of the cyclone from the International Space Station that Robert Reeves found for me. Astronaut Don Pettit couldn’t get a good pass for a photo out the windows as it was happening but this early one from the external cams is a cracker!

Haven’t posted a nebula on here for a while as I’ve been enjoying the planet season but it’s time to get back to space clouds :) This Rosette Nebula shot is a mere 42 minutes of data with a new portable telescope I bought (a Petzval Quintuplet!) and the QHY minicam8 and q-focuser. It actually wild how well this combination performs! Perfect sampling, sharp stars, flat field. Behind the scenes video on my YouTube.

This image of the Sun is a little different from my others as it was captured with a spectroheliograph that “scans” across the Sun’s hydrogen-alpha spectral line in a single 20 second pass to produce an excellent image of the surface details and outer activity at the same time. It’s a first attempt so I should be able to improve this with some more learning! To see how this image was captured see this video : https://www.youtube.com/watch?v=12i19HO1CIc

Seeing was decent enough last night, so I gave the C14 a spin on the two biggest players of the “planetary parade” this year. Mars is much smaller in 2025 and was twice this size in 2018! Ice cap and clouds still resolvable though. Io is also visible hiding in the GRS’s wake.

I’m returning to an old favourite of the souther

I’m returning to an old favourite of the southern summer nights, M42 Orion. But this time, I’ve come back with a itty bitty little telescope and a new camera from @qhyccd_astrophotography (miniCAM8) which they sent me for testing. I’m very lucky to get to use this camera before most people can even buy one (thank you!). It’s now my current recommendation for any beginner wanting to get into astrophotography with a small telescope. I’ve got a whole video about it here : https://www.youtube.com/watch?v=11HNh_n5JrI

I can’t believe this is only 1 hour of data from a complete rig worth $2.8k USD!

Last night’s Jupiter! C14, QHY678m, EQ8Rh-Pro, Esatto Robotic Focuser. Stacked in AS!3, Wavelets in Astrosurface, Derotated with WinJupos. No Barlow, just native! Behind the scenes video on the capture on YouTube. Sorry for Jupiter spam, just in the zone while it’s close to opposition and nice and bright and highish at 40 degrees.

Colour version of Jupiter from a few nights ago with its 2nd largest moon, Callisto and the GRS slowly rotating into view. C14 / QHY678M .. excited to get this detail with no barlow.. Still learning though! #astrophotography #celestron #qhyccd

I can’t believe this worked! This is the highest

I can’t believe this worked! This is the highest focal length / zoom I’ve ever imaged a deep space object that isn’t a planet. There is a behind the scenes video on some of the interesting features but in the main star cluster is the largest star we know about, surrounded by a dense group of blue supergiants and wolf-raylet stars. This nebula is not in the Milky Way, it’s in a neighbouring galaxy!

First deep space photo from my shiny new Celestron 14” Edge HD telescope, pushed to its maximum native focal length of 3,910mm!! I’m shocked.
