Home: Galaxies, Nebulae, Comets. They all can be inspiring.

There are many interesting galaxies and nebula for the amateur astronomer to observe. This website shows some general objects, as well as some more challenging peculiar galaxies, multiple systems and galaxy clusters. Every now and then, new CCD-photos and observing notes are added, to show what can be interesting and fun to observe.

 

This website shows some highlights gathered from the cosmical zoo. Most deep sky photos have been taken with an STL-11000M camera. Browse and pick your favorites to observe at your next observing session.

The Observatory: The observatory dome is situated on an island northeast of Stockholm.

Northern lights observed in Umeå, Sept 4, 2022:

There was a pretty strong aurora with Kp values around Kp6. The activity was ongoing the whole night.This is a time lapse with reduced resolution. More images under the Aurorae folder.

Eruption and Flare in AR 3088 on August 27, 2022: This group was extremely active with several M class eruptions. North is to the left.

The sequence is from 13:11 UT to 13:19 UT.

FLARES in AR3078 on August 17 and 18, 2022: The 3078 group area went crazy around August 17-18 with several flares. Here are images from 13:59 UT on Aug 17, and 11:10 UT on Aug 18.  Intense bright flares were observed that changed rapidly. Taken with a WO 90mm refractor and a Quark Chromosphere filter. 

AR3032 on June 15, 2022: This group is very complex and full of details. This is the first photo with a new setup using a 90mm refractor and a Quark Chromosphere filter. Detail below in BW some 24 min later.

AR3031 and 3037 on June 16, 2022: Another showpiece with fine details.

AR2938 and AR2936 on February 1, 2022: The new solar cycle has started with some vast and interesting regions. Also some great prominences, as the one from Feb 5th. Taken from Nice, France.

Nova Cassiopeiae 2021, V1405 Cas:

The nova is in the middle left portion of the image. To the right we have the Bubble Nebula NGC 7635.

The BW photo shows the nova in the center at magnitude 8.2 on March 22.

The spectrum curves are taken with a SA200 grating. Details in the Spectroscopy folder.

IC1805 and Melotte 15 in the Heart Nebula: This is a Ha-SHO representation of the center part of IC1805. 

M81: Messier 81 is one of the classic spirals in the constellation Ursa Major.  To the left, there is a tiny "smudge", which actually is a faint satellite galaxy. It is denoted Holmberg IX, or UGC 5336. 

Giant Solar Prominence: This humongous prominence developed rather fast from July 30 to 31 (2020), and blew off the sun around mid-day July 31. I followed the eruption during a few hours, where large parts of the prominence material was thrown out into space.

M82: Messier 82 lies just a little north of M81. the center of the galaxy shows a violent and chaotic appearance. There is vivid starburst activities in this very luminous galaxy.

Abell 39: This is one of the more tricky planetaries to photograph or visually observe. Several faint galaxies can be seen through the bluish dish. The largest is at position "2 o´clock", and there is one at position "6 o´clock".

Comet NEOWISE: The great comet of  the summer of 2020. when it was closest to earth. The comet was very bright, but hard to image, since the sky was not dark. Just a bright twilight on this July 23-24 image. Note the visible ion tail.

M101

M101: In Ursa Major you find this nice spiral galaxy, which is fairly close to us. It shows lots of interesting HII regions.

Below: Observing from downtown Stockholm can be challenging, but gives also new opportunities. Here we see the young moon just over the well known landmark, the DN Newspaper building,, in central Stockholm.


Below: Dramatic Prominences - The big Solar prominences of June 17, 2017. Photographed with a small 60 mm solar H-alpha telescope.

Venus and the Pleiades:  In April 2020, Venus made a nice visit to the Pleiades. One could follow the transit for several days. This exposure is from April 04, 2020.

Comet Lovejoy

Comet 21P: Comet 21P/Giacobini-Zinner on September 15/16 2018. It passed just south of the open clusters Messier 35 and NGC 2158 in Gemini.

Below: Magic Evening - The passing Swan created a Light Winged Golden Bird out of the reflected crescent moon - May 9, 2016

Set of Four: An almost classical set of prominences on Sep 9th, 2018. The development of the eruptions were interesting to follow. They looked like textbook examples.

The Sun in H-alpha: A very prominent prominence shows up at the suns limb on June 25, 2017.

The Sun in H-alpha: Active Region AR 2665. A nice prominence is visible at the limb. Taken at July 15, 2017 with a 60mm Solar telescope.

Below: On January 2019 there was a magnificent Lunar Eclipse visible in the early morning hours. In Stockholm it had its maximum around UT 05:12.

Active Sun:  Active region AR2665 and some very nice prominences on July 8th, 2017, on the eastern limb of the sun.

Majestic Universe: The Cirrus Nebula in eastern Cygnus has an incredible amount of interesting veils and structures. The old supernova remnant is dominated by the red colour of hydrogen clouds, and the teal colour of oxygen features in the gaseous clouds.

Magnificent Sky: The Milky Way above. Looking at the open sky from a dark location is a wonderful experience. This image is from Fårö/Gotland and taken together with Marie and Michael Bergström.

Incredible Universe: The North America Nebula and Pelican Nebula in northern Cygnus. SHO Hubble palette colours.
