May 25, 2015   -   We've enjoyed a couple of good observing nights lately but since it's been rather "breezy" to put it mildly, I decided to put my new 135mm f/2.8 Mitakon Zhongi lens through some more tests mounted piggy back. This is an old fashioned clunky (heavy) all metal, manual type lens. As you can see, when closed to f/4, plus the IDAS LPS-V4 filter, it performs remarkably well with the Canon 6D. Tack sharp to the edges and no vignetting. Not bad for $200 lens made in China of course.

The NA Nebula area is a stack of 1 + 2 minute exposures shot at ISO 3200; and the Antares is a 6 x 2 min stack.

May 03, 2015   -   One good thing about cloudy nights and full moon times is that I get to play with some of my old deep-sky images and try to improve them after learning some new processing and stacking tricks. This one is a composite of some 16 images of the ghost-like California Nebula taken over a period of 4 years with 2 different cameras (modified Canon 50D & 6D) and 3 different refractors (TeleVue 101, TMB-130 & 92) and 2 different filters (IDAS-LPS-V3 & V4). Cumulative exposure of the composite is about 50 minutes at ISO 800-3200. These were stacked and processed in PS CS6, using the HDR application which gives a 3D- like appearance.

Moral of the story? Don't delete your older images for at least 4 years :-)
