More 6D Wide-Field Shots

Eventually, I’ll have to get serious about using the Canon 6D for astro-photography.  Specifically, I’ve only done exposures up to 30 seconds, the maximum the camera will do by itself (without a computer or other device controlling the camera).  The results have been mixed (I’m only showing you the ones that worked out well), but with longer exposures and lower ISO settings I think it can produce some spectacular results, both with wide angle lenses and telescopes. But until then (and “then” could be a while, given the usual weather patterns here this time of year), I’ll share a couple […]

Cygnus Wide Field

I mentioned in a previous post that I still had some unprocessed images from last Summer.  Honestly, I still haven’t had a chance to do much with them, but here is one example, a wide field shot of the center of the constellation Cygnus.  This was captured with a Canon 6D full-frame DSLR, with an 85mm f/1.8 lens.  It consists of just 8 frames of 30 seconds each (at ISO 6400).  The camera was modified for Hydrogen-alpha sensitivity, which is why we can see an abundance of red.  The brown regions are primarily dust and the grey is just a […]

The New Face of Mr. T

“Mister T” is the simplest and most popular of my products.  Most amateur astro-photography is done with DSLR cameras, and most of them are Canon EOS type (EF or EF-S mount).  To attach such a camera to a telescope requires some kind of adapter and for that we turn to the old concept of the “T ring”.  The T ring was developed long ago as a way for 3rd party lens manufacturers to produce lenses that could be used on many different kinds of cameras by standardizing on a simple threaded connection on the lens (“T threads”), and reducing the […]

I’m Still Here!

Wow, it’s been more than 2 weeks since I posted here, which is unforgivable.  And the truth is I don’t have the time right now to write anything insightful, important, or entertaining, so I’ll just give you a quick report on what has been happening here at Wa-chur-ed and in the world of astronomy. Most of my time has been consumed lately by a project to change the floorplan in my motorhome/mobile gallery.  I have removed the dinette and replaced it with a couch.  The idea here is to create more open space so that people can move around more […]
