More data for M16

Petri Kehusmaa — Thu, 08 Jul 2010 12:21:35 +0000

We shot some more RGB frames for M16 with NG Telescope. Now the total exposure time for LRGB is 215 minutes.

Latest image from Australia is M17 alias Swan Nebula. This is a narrowband image taken with Ha, OIII and SII filters. Exopsures are Ha:OIII:SII=120:20:40. Ha was also used as luminance layer in Photoshop.

Here is an other example of a beautiful galaxy with great halo and lot of smaller galaxies in background.

Equipment: 16″ RCOS NG Telescope + Apogee U9000 + Astrodon LRGB filter set

M20 with 16″ RCOS NG Telescope

Petri Kehusmaa — Thu, 20 May 2010 19:10:49 +0000

Today I was able to continue using this magical telescope in Australia. Scope was operated by Bert Candusio locally and I used the control computer with VNC.

M83 with NG Group’s 16″ RCOS Truss f/9

Petri Kehusmaa — Mon, 17 May 2010 19:48:20 +0000

Yesterday I subscribed as a user for Northern Galactic Group’s remote control telescope. Today I was able to use 16″ RCOS Truss f/9 telescope on Paramount ME mount equipped with Apogee U9000 CCD for more than 4 hours . The scope and the camera is a VERY POWERFULL combination of imaging equipment, not to forget the mount.

This is only 80 minutes of total exposure of M83. Very basic image processing.

Imaging Camera Out for Repairs

Petri Kehusmaa — Tue, 12 Jan 2010 08:59:08 +0000

Eventually I had to sent my STL-11000M camera to Baader Planetarium (Germany) for repairs. There might be a problem with TE cooler or power source. It’s gonna take at least a month to get my camera back. If weather allows, I’m going to pursue few CVs with nice light curves with my ST-7XME camera.

M42 Revisited

Petri Kehusmaa — Wed, 09 Dec 2009 06:19:39 +0000

I’m going through my old images and reprocessing them with new tricks I’ve learned after watching Adam Block’s DVD. Here is M42 from last year.
