The Rosette Nebula

If you look just to the top left of Orion, there’s a small, unassuming, cluster of stars.

It doesn’t look like very much. Even a single, ten second, camera exposure doesn’t reveal a great deal.

However, if you persist in taking photos for about half an hour, and then artificially brighten the result, you get this.

This is the Rosette Nebula. Taken last night, 22 Feb, with my Seestar S50. This description from Wikipedia.

“The cluster and nebula lie at a distance of 5,000 light-years from Earth[6] and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.”

  1. just saw this, apologies to those already aware: “Skywatchers are in for a treat this week as seven planets – Mars, Jupiter, Uranus, Venus, Neptune, Mercury, and Saturn will all be briefly visible in the evening sky.

    This phenomenon, known as a ‘planetary parade’ is a rare sight, and it will be the last time seven planets can be seen simultaneously so well until 2040.

    The best chance to see as many planets as possible will be just after sunset on Tuesday, Wednesday, Thursday and Friday.

    Four of the planets – Mercury, Venus, Jupiter, and Mars – will be visible to the naked eye. Saturn will be harder to see because it will be low in the horizon. You will need a telescope to spot the other two planets – Uranus and Neptune.”
