The Rosette Nebula

December 28, 2025 by Brian Ventrudo Filed Under: Deep Sky

The heart of the Rosette Nebula and the open cluster NGC 2244 that is emerging from it. Captured with a ZWO Seestar S50 telescope.

Look to the east of mighty Orion and you’ll see the constellation Monoceros, the Unicorn. While its stars are faint, Monoceros holds a small treasure chest of superb deep-sky sights for backyard stargazers. Perhaps the most striking is the Rosette Nebula, an achingly beautiful blossom of glowing gas and dust where new stars are forming.  The Rosette is an immense nebula, some three times larger than the Orion Nebula and three times farther away.  As you see in the image above, captured with a little ZWO smart telescope, the nebula overlaps the star cluster NGC 2244 which formed within the nebula and blown a bubble to give us a look inside. While can be a challenge to see the Rosette visually, even in large telescopes, the nebula is an excellent photographic target and the cluster offers a superb sight in binoculars or a telescope [Read more…] about The Rosette Nebula

A Visit to the ZWO Factory and a Glimpse of the Future of Amateur Astronomy

December 15, 2025 by Brian Ventrudo Filed Under: Astronomy Equipment

Nico Carver visits the ZWO factory and offices in Suzhou, China and speaks with founder Sam Wen about the development of some of ZWO’s most innovative products. This short video offers a insightful glimpse into the process of conception, design, and development of successful new products – an art in itself. And it gives us a peek over the horizon of the direction of how compact, ‘smart’ imaging telescopes will influence the future of amateur astronomy. In my view, Sam Wen and his team have done more to get people involved with hands-on astronomy than anyone in the past two or three decades. They have done super work.
