These images are the latest images taken remotely with Searchlight Observatory Network’s equipment.

Latest New Mexico addition, supernova remnant PK164+31.1. This is one of my favorite nebula and I will try to shoot LRGB later when the Moon and weather allows.

This is 200 minutes of Ha.

Searchlight Observatory Network, NM, USA.

Latest image is the famous Monkey Head Nebula. This image is a combination of Ha and LRGB frames taken in New Mexico with Searchlight Observatory Network’s 16 inch RCA and Apogee Alta U42 CCD.

Long time since last post. I’ve been very busy with my regular day job which has demand a lot of my valuable ‘free’ time as well. Last night was clear and moonless for a long time so I kicked my self out to shoot some additional frames on this challenging target. Now I have total of 5.5 hours of data. I’ll continue shoting this when time, clouds and moon allows.

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.

RGB image of this great looking nebula. Exposures RGB=25:15:20 minutes only!

Me and J-P Metsävainio were able to get some more images for this nebula. Here is updated version with new data added.

This is v0.1 of this beautiful nebula. Mora data needs to be acquired.

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.
