Imaged in San Pedro de Atacama, Chile. Searchlight Observatory Network, Planewave 20″ CDK + Apogee AltaU42 on Paramount ME.
This beautiful nebula consists of large HII region and some nice dark and reflection nebulae. Here are total of 174 minutes of HaLRGB frames combined.
SON, Atacama Chile.
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.
Imaging color images with photometric filters might surprise you. I was certainly surprised of the green color of this nebula. Real color should be red because of strong Ha emission but obviously Rc, V and B filters disagree with that. Nevertheless this is total of 50 minutes exposure taken from 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.
This beautiful galaxy raises just above 30 degrees in New Mexico when at meridian. I was able to image this visually huge galaxy in two nights totaling exposure time of 186 minutes.
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.
Another image from NM couple nights ago. This galaxy is also called the Sunflower galaxy. Total exposure of 120 minutes.
Another nice globular cluster from NM. Total exposure 77 minutes.
