An extremely cold night under the stars with the Canon 18-135mm f3.5 -5.6 IS lens.
I shot the lens at 18 mm and at 135mm to get a feel for the ability of the lens. I found it to be reasonably well corrected with a certain amount of coma and chromatic aberration at the edges although to be fair not as much as I had anticipated.
As always with Canon DSLRs the 600D tends to be red heavy on the sensor. I have yet to determine why this is the case with these cameras as it makes post processing difficult. Ambient temperature was a balmy 2 degrees Celsius when I began the session and was subzero by the time I had finished.
The first image is a wide field view – shot at 18mm, ISO 3200 for 15 seconds. A stack of eight images.
The second image is shot at 4 seconds at 135mm as is the third image. A stack of thirty three images.
The third image is of Messier objects M7 and M6. The larger of the two star cluster is M7 at center frame. Stack of twelve 4 second images.
Having a proper mount to sit the camera on would be a big benefit. The lens looks to be quite useful even if it isn’t an f2.8 lens. Currently I am considering getting an iOptron Sky Guider Pro and a suitable tripod to mount it on.
As always Happy Snappin’
