North America Nebula – Canon 50D

Posted on Updated on

North America Nebula… An object I always loved and I always feared. But still beautiful and amazing in its detail and charming appearance. I also see the symbolism behind it now when I’ve moved to US with family and kids. It was time to grab the bull by its horns and look at it straight in its eyes.

This image consist of 12 separate exposures between 2 and 2.5 minutes each at ISO 1600 with a Canon DSLR taken 10/26/2019. I’ve made an unprocessed blog post earlier about this nebula, but really never had the time to technically deep dive into post-processing and stacking. I thought since I’m about to write an article on the Observer in its coming issue about postprocessing and I’ve chosen Nebulosity, why not give it a try. I’m kinda allergic to try something more expensive than that, such as PixInsight. One day I’ll get my hands on it too.

So here we are… Behold The North America Nebula a.k.a. NGC 7000. Quite wide object (120 x 100 arc minutes) in one of the most interesting constellations of the northern hemisphere, Cygnus.

Image was taken through William Optics FluoroStar 110, with a Canon 50D DSLR, EQ6 Pro mount.

But all in all… I still don’t give up on this object… I’ll be back soon to collect more of its distant and faint magnitude 4 light!

There’s once in a while a comet coming by and I missed some really good ones in my life… I thought I won’t let this one go by unnoticed … I took light gear with me in the car and off I went to the highest point in Folsom to overlook towards the eastern horizon. Fortunately I scouted a nice little area that is not surrounded by tall buildings around. The photos were taken with my William Optics Megrez 72 FD APO and a Canon EOS 50D camera. Various exposures from 2 to 3 seconds depending how high it was climbing during the sunrise and the sunlight began dominating… ISO settings were varying between 800 to 1600 as I was playing around. Tripod, remote shutter hand controller…

Great American Eclipse – More photos

Posted on Updated on

Three days after this magnificent eclipse I managed to process through some more photos out of my camera’s memory card. Unfortunately, I didn’t get to capture the diamond ring before the totality, just the one the came afterwards. Regardless, I am happy the sun got sunspots 2671 and 2672 clearly visible. It made the job a whole lot easier.

All images were photographed with a Canon EOS 50D, DSLR camera on prime focus method on a William Optics 110mm FLT APO f/7.0 telescope. While the live video on Youtube at the day of the eclipse was a Samsung Galaxy S7 phone with afocal method on a 32 mm ocular attached on a William Optics Megrez 72mm FD f/6.0.

The camera settings were, ISO-500, shutter speed at 1/3200 sec., 6000 K and the wheel setting was on M (manual mode).

Sunspot observation

sunspots 1195, 1196, 1193

Enjoying Easter holidays with a bright shiny and sunny day with my telescope. Considering it has been very nice weather during the entire holidays here in Sweden, this must have been the best as there are two sunspots appearing on the surface of the sun (1195, 1196 and 1193).

This image was taken by using a Mülar filter installed infront of my refractor (William Optics Fluorostar 110 FLT APO) at ISO 100, shutter speed 1/800, WB: 7500 K and was processed with curves and levels adjustments in Adobe Photoshop.
