California Nebula

NGC 1499 – The California Nebula by Trevor Jones

 

Canon Rebel Xsi – Recently Modified 450D

I am proud  to say that I am now the owner of a Modified 450D.  My recentself-modification has really helped bring out the colour of this Emission Nebula.  If you are interested in modding your own Canon Xs or XSi, you can find the tutorial from Gary Honis below. The photo above was taken on the night of October 25th under clear skies in Wellandport, Ontario. I feel like I want to shoot every deep-sky object over again now that my camera records so much more red nebulosity!  I am excited to image some of the Winter objects that will be spending some time in our night sky over the next 2 months!

Compare the single frame to the stacked image of over 2 hours and processing

 

NGC 1499, or “The California Nebula” is a large emission nebula located in the constellation of Perseus.  It’s shape resembles the outline of the State of California.  The California Nebula is very difficult to observe visually because of it’s low surface brightness, but shows up well in long exposure photography.  It was discovered by E.E. Barnard in 1884.

Canon 450D / 1000D - Gary Honis Full Spectrum Mod

Gary Honis will take you step by step of how to remove the IR cut filter in your Canon XS or XSi in the video below. Removing this filter from the camera allows H-Alpha wavelengths to pass through for deep-sky imaging. I was able to modify my DSLR myself by watching this video. I performed the “full-spectrum” mod, and did not install any additional new filters to the camera. I only removed the IR-Cut filter. My clip-in Hutech IDAS LPS filter protects the sensor.

Autumn Stars – Pleiades Rising

Last Saturday I spent a very cold, but very dark and clear night at the RASC Observatory in Wellandport, Ontario.  There were 4 of us that stayed the night, and I think every one of us complained about being underdressed!  I began my night by shooting NGC 7293 – The Helix Nebula.  I have never tried to shoot this object before, and to be honest, I didn’t think it was possible from Southern Ontario.  I ended up with about 2 hours on it, but I think I will need to double that to really bring out the detail.  As you can see, my unmodified Canon 450d makes this object look rather bluish-purple.

NGC 7293 – The Helix Nebula

My main focus for the night was The Pleiades.  This wonderful star cluster is located in the constellation Taurus the Bull.  At this time of year, Taurus is just starting to rise high enough in the East to start photographing Messier Object 45, the Pleiades open star cluster. I imaged this object last year, and was relatively happy with it, but I have learned a lot since then!  The details of the above photo (of Pleiades) are as follows:

Removing Reflections in M45 image

Astrophotography processing The Pleiades

The autumn stars seem to shine extra bright as they bring in the winter constellations behind them. M45 can be surprisingly challenging to process, considering the inherent reflection issues that may arise.  The healing brush in Adobe Photoshop is helpful in removing the unwanted halos and reflections in your image.  You will definitely want to be careful not to remove any background stars or nebulosity in the process!

I will probably give it another shot once I have added more time.  I am looking forward to re-doing Orion once it stays up for a little bit longer.  Thanks for looking!
