DeepSky Observations: March 2009

http://deepsky-astronomy.blogspot.com/2009_03_01_archive.html

Welcome to the Deespky Blog of Olivier Van Aelst - Belgium. Sunday, March 8, 2009. Good deepsky conditions, even with moon! The sky looks very transparent, but unfortunately the moon is already quite bright. Without moon I guess we would have more than 5,5 nelm. I estimate it now to be 5,0 but deteriorating at the end of the session due to upcoming clouds. Date: March 2, 2009. Equipment: Obsession 18”. Eyepieces: 24mm; 16mm, Powermate 2,5x. Time 19:15Hr UT to 22Hr15 UT. NGC 5879 – galaxy in Draco. A roun...

DeepSky Observations: January 2011

http://deepsky-astronomy.blogspot.com/2011_01_01_archive.html

Welcome to the Deespky Blog of Olivier Van Aelst - Belgium. Sunday, January 30, 2011. Again supernova SN 2011B. Estimated magnitude: 12.6 (FWIW .). Jan 29, 2011 - around 22:00 UT. Sky conditions not very good, limiting magnitude below 5. Saturday, January 29, 2011. I want to see Supernova SN 2011B in Cameleopardalis – 28 Jan 2011. I have a twofold objective for this night, first it’s to catch the supernova in Cameleopardalis, and then the last 2 Herschel II galaxies in Eridanus. Nelm: above 5,0. The obje...

DeepSky Observations: Found Pease 1! And tested some nice eyepieces (16 August 2009)

http://deepsky-astronomy.blogspot.com/2009/08/1682009-found-pease-1-and-tested-some.html

Welcome to the Deespky Blog of Olivier Van Aelst - Belgium. Monday, August 17, 2009. And tested some nice eyepieces (16 August 2009). Again a nice and clear sky, the 3rd in a row. I don’t need to work tomorrow so no worrying about staying late. I have tonight also the opportunity to test some eyepieces (thanks to Hubert). I have an Astrolan ultrawide 30mm (80°). Which provides me with a FOV of 1,2°, as well as a 9mm Nagler T6. The discontinued version) . 1 The first object was M13:. Note 1: while testing...

DeepSky Observations: February 2009

http://deepsky-astronomy.blogspot.com/2009_02_01_archive.html

Welcome to the Deespky Blog of Olivier Van Aelst - Belgium. Sunday, February 15, 2009. My wife loves me! She gave me as a present a clear night on Valentines day, and not only this, she let me observe! The sky is indeed clear, although not very transparent. It’s difficult to see all the stars of the little dipper. I estimate it’s just nelm of 5.0. The weather is still quite cold, this night is going to be below zero again. Location: Boutersem (at home). Equipment: Obsession 18”. Nelm: close to 5.0. NGC 4...

DeepSky Observations: April 2008

http://deepsky-astronomy.blogspot.com/2008_04_01_archive.html

Welcome to the Deespky Blog of Olivier Van Aelst - Belgium. Wednesday, April 23, 2008. 2nd" light with the 18" Obsession. Yesterday evening I had my "2nd light" with the Obsession. Again a nice success, as the tracking and the goto were performing well this time. The issue was just the ArgoNavis cable, it was not fully plugged in the ServoCat. So problem solved - all works well. Today I had also dew on the secondary. I did not fix the dew heater yet (not sure which type of glue I need) but I feel the...

DeepSky Observations: May 2009

http://deepsky-astronomy.blogspot.com/2009_05_01_archive.html

Welcome to the Deespky Blog of Olivier Van Aelst - Belgium. Sunday, May 31, 2009. A good mix of galaxies, planetaries and open clusters. While I’m slowly finishing the Herschel II list, I decided to go for a new challenge, the Fred 200 planetary list. Fred H is a Dutch astronomer who has extensive experience in drawing planetary nebula’s. He has seen 280 planetary nebulas with a 20cm scope (from Holland! You can find this list here. Date: May 30, 2009. Equipment: Obsession 18”. I have a difficult start&#...
