Centaurus A - I had hoped to capture more than 100 hours of data on this fascinating galaxy this, but have called it quits (at least for now) with 30 hours in the bag. Captured with the RASA 8 & ASI 533MM and TS 94EDPH $ ASI2600MM. See https://t.co/Kq3P6kQSns #astophotography

My Southern Pinwheel Galaxy image has won first prize in the Astronomical Society of Southern Africa Astrophotography competition of 2025! Really happy that the 70 hours of integration time paid off 😁 #Astrophotography #space #astronomy

I started this project 4 months ago and it’s finally done. Here is my final image of the Southern Pinwheel Galaxy (M83) in HaLRGB. Telescope - TS Photoline 140, camera - ASI2600MM, integration time - 60 hours. Captured from Newlands, Cape Town (Bortle 7/8) #astrophotography #m83

50 hours on the Pencil Nebula. Captured in HOO with the RASA 8 & ASI533MM Pro. #astrophotography #pencilnebula

@MIKETAYLOR21344 @zwoastro @TeleskopService @Celestron Not fake. Captured with standard astrophotography equipment, with minimal processing. Isn’t space beautiful!!

Part of the Vela Supernova Remnant, captured in HOO with the RASA 8 & ASI533MM Pro. 30 hours of exposure time. #astrophotography #space #astronomy

@SpaceBiz1 @zwoastro @TeleskopService @Celestron Sure. Just credit. Thanks!

This image of M 104 was captured in one night from the Cederberg Observatory using a SW Esprit 100 & @zwoastro ASI2600MC Pro. This is a stack of 60 300 sec subs, so an effective 5 hours of exposure time. #astrophotography #space #sombrerogalaxy #M104

….. and here is the wider field version 😎 #horseheadnebula #space #astrophotography #astronomy

@clarkjames70 Let me know when you are here, maybe you could visit the Cederberg Observatory.

The Horsehead and Flame Nebulae captured with two telescopes - the RASA 8 & ASI294MM for the Ha and the Esprit 100 & ASI2600MC for the colour #horseheadnebula #astronomy #astrophotography #space

@clarkjames70 Thanks James. Everything was done in Pixinsight.

What do you do when you get out to dark skies? Well, it’s obvious, right? You capture one of the most iconic objects in the sky….The Horse Head Nebula. This is a little under three hours using the SW Esprit 100 and the ASI2600MC Pro, captured from beautiful Gecko Rock reserve.

A quick peak at my wonderful hobby 😀 #astronomy #astrophotography #outreach

The Cobra and Mouse (NGC 2442 and NGC 2443) are two parts of a single intermediate spiral galaxy. It is about 50 million light-years away in the constellation Volans. This is the first part of this project consisting of luminance data. Colour to follow. #astrophotography #galaxy

Always better looking up ✨#astronomy #astrophotography
