Chile 20″ CDK ‘LRGB First Light’, NGC 4945

I have started to operate a 20″ PlaneWave CDK telescope in San Pedro de Atacama. It’s mainly used for scientific surveys but every now and then I have opportunity to take some pretty pictures. Conditions are excellent down there. Average seeing is around 1.8 FWHM, sometimes even less. This observatory is sponsored by Caisey Harlingten.

I’ve been configuring ACP automation software to be able to automate most of our observations. We are also changing the dome control electronics to be able to operate it remotely.

This is 172 minutes of LRGB data.

IC 434 a.k.a Horsehead Nebula First Light in Chile

This is my first light using using 20″ PlaneWave CDK telescope in Atacama Chile. I was using only photometric filters to acquire colors for this magnificent nebula. Total exposure is 84 minutes.

IC-434-RGB-v01

NGC 6888

I had a chance to shoot one moonless night in the middle of the monsoon at New Mexico. I picked up this target because I already had some data for it from previous sessions. This is total of 291 minutes of HaLRGB frames combined together with Photoshop.

M63 Galaxy

Another image from NM couple nights ago. This galaxy is also called the Sunflower galaxy. Total exposure of 120 minutes.

M14 Globular Cluster

Finally back in business. Two months since I was able to operate our remote observatory in New Mexico due broken motor to open up the roof. Now it’s fixed. First test image of the RC1. This is total of 80 minutes of LRGB exposures of this nice globular cluster.

Second 16″ RC Operational in New Mexico

After long wait and a lot of work and configuration I’m happy to announce that we have our second operational RC telescope in Rancho Hidalgo. Thank you Mark Hanson for your valuable help.

Two 16" RCs

M78

This is M78 image where data is combined from last year and this year. LRGB = 40:40:30:40 minutes.

Framing was a bit challenging due to lack of guiding stars.

NGC 6914, Reflection Nebula in Cygnus

This image is taken with the 16 inch RC in Rancho Hidalgo, New Mexico. It consists of 30 min total exposures per color channel. All subs are 3 minutes in duration.

Imaging Comet C/2012 S1 ISON

Currently imaging comet ISON in New Mexico. Almost full Moon is lighting the observatory at Rancho Hidalgo. Comet was very low above the horizon (27 deg) and it was just visible to telescope above observatory wall.

Paramount at RH

And here is the result, 4min exposure (30 sec subs) where stars and comet stacked separately and combined.
