Rush hour on the Sagitta-Vulpecula border

Yesterday, while preparing the series of images on comet 2009 P1 Garrad (see previous post), I captured below 10 second exposure using the Samyang 1.4/85 mm lens. The telescope mount was not yet adequately following that time.

It shows satellite rush hour on the Sagitta-Vulpecula border: as much as four objects in this single image measuring less than 10 degrees!

11-037B is related to the SPEKTR R (Radioastron) launch. Kosmos 530 (72-087C) is clearly slowly flashing.

Later that evening, I captured the FIA Radar 1 (10-046A) passing through Cygnus amidst whisps of clouds, making for this eerie picture (made using the Canon EF 2.5/50mm Macro):

OT: comet 2009 P1 Garradd with the new 1.4/85 mm lens (updated)

Yesterday evening (30 Aug 2011) started reasonably clear, so I set up the small Meade ETX-70, put the Canon EOS 450D with the new Samyang 1.4/85 mm lens piggyback on it, and made a series of images of the Sagitta-Vulpecula border area, where comet 2009 P1 Garradd is currently located.

Sky conditions were variable. Out of 97 images (of 10 seconds exposure each), I selected the 34 best for the stack below. The comet (small, but with a clear tail) is in the center, parts of Sagitta with M71 are at left, the "coathanger" cluster is at right:

NOSS 2-1 (C) very bright

In the evening of August 28, during a short clearing, I was testing a new lens, the very fine Samyang F1.4/85 mm Aspherical IF.

The EOS 450D with the lens was mounted piggyback on my Meade ETX-70, with the ETX following the movement of the stars.

While making a series of images of the Deneb area, situated near the zenith, a bright naked eye satellite of mag. +1.5 passed through Cygnus and the camera field.

On the image, it turned out to be accompanied by two other satellites, much fainter. It actually was the NOSS 2-1 trio, and the bright one was the (C) component (1990-050C). Below is the image:

NOSS-es usually do not get this bright in the zenith and I have never seen 1990-050C this bright before. Scott Tilley from the USA has recently observed the same unusual brightness of NOSS 2-1(C), and so did Brad Young.

The lens I was testing, the Samyang F1.4/85 mm Aspherical IF which gets raving reviews on the internet, turns out to be an extremely fine F1.4 lens. The optical quality is astounding, and this at a cost of only €269,- !
