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.

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.

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.

About this dataset

This dataset captures the Great Orion Nebula (NGC 1976) and surrounding complex, acquired over six nights in early December 2025. The imaging setup used a Rokinon 135 mm F2.8 lens paired with a ZWO 533MC Pro camera on a Sky-Watcher Star Adventurer GTI mount. The data comprises 360 unfiltered frames at 180 seconds each, totaling 18 hours of integration time. The wide field of view at 135 mm encompasses not only the bright core of M42 but also the broader molecular cloud region. This substantial integration period provides deep signal across the nebular structures, making the dataset suitable for processing projects that emphasize faint outer regions or color gradients in the ionized gas. Released under CC0 1.0 Universal, the data is available as a free download with no copyright restrictions.
