Description

NGC 3293 — The Gem Cluster
A young, jewel-like open star cluster in the constellation Carina, about 8,000 light-years away. NGC 3293 is one of the youngest known star clusters in the southern sky — its bright blue main-sequence stars are only 6-10 million years old, which is the cosmic equivalent of yesterday. Mixed among them are a handful of red and orange supergiants that have already evolved off the main sequence in spite of the cluster's youth — these massive stars burn through their nuclear fuel astonishingly quickly, sometimes in just a few million years. The contrast between the hot blue young stars and the cooler red supergiants gives the cluster its jewel-box appearance. NGC 3293 sits within the much larger Carina molecular cloud complex; the diffuse red Ha emission glowing across the field is ionised hydrogen from the cluster's hot stars lighting up the surrounding gas, sometimes catalogued as Gum 30. The dark voids on the lower-left of the field are dense dust filaments threading through the wider Carina region.

Captured from Willoughby in suburban Sydney (Bortle 7) over 4 nights in early May 2026 — tight narrowband filters make targets like this accessible from urban skies. 20.8 hours captured under the mid moon.

The quality of the data downloaded from Astrophoto was of good quality. It appears that the servers can only upload data at about 10Mbps, so my download speed was restricted to that value. Based on my exploration of the site, the value for the data within is quite good.

Good quality! And for me it's just great, since being on a low budget, that I can download files for practicing the world of editing Astro-Images.

Generally good quality image and from my experience the subscription is a good value. I always align and crop the downloads to avoid any edge issues during gradient removal. Chris has always been very responsive to questions. Recommend!

Thanks I have quite a few data sets waiting but the ones I have processed have been excellent. I do not yet put any iimage on line as I have had many health issues and difficulties with software and hardware. I am a 73 year old learner with defective colour vision and barely 3 months using PixInsight and Photoshop cc so it is as steep for me as it is difficult to see stars in my letterbox of Bortle 7 city sky…

This was a fun image to process, especially since I had never worked with the Askar D2 filters before. One thing to note is that the three files are not quite star-aligned correctly, so be sure to do that first before processing these data yourself.

I'm getting to grips with PixInsight and needed some real world data files. Astrophotomarket seemed to be the best choice and recommend.

I can say I definitely made the right choice for data files.

Not ready to publish yet but will do so as soon as I can.

La qualité des images est vraiment très bonne.
Quand la météo est mauvaise, comme chez moi depuis des semaines, c'est vraiment un plaisir de pouvoir s'entrainer avec ces données.
Je recommande !! //English: The image quality is really very good.
When the weather is bad, like where I live and it has been for weeks, it’s truly a pleasure to be able to practice with this data.

Great data. I am a PixInsight newbie but have 6 months of astrophotography experience courtesy of Seestar. Once I workrd out how to process the mono narrowband files I was able to produce a very acceptable image. I think. It isn’t goung on line but I printed it for my collection. Thank you!

I could not be more pleased with this, my first purchase of data sets from AstrophotoMarket.com. To begin, I found the website easy to navigate and replete with the information I needed to make an informed purchasing decision. Payment was quick and easy, and the data sets became available for download promptly after I made payment. As for the quality of the data, it matched my high expectations. Processing the data sets was a pleasure, and I am thoroughly satisfied with the resulting images. I am certain that I will be availing myself of AstrophotoMarket.com data in the future.
