A "remote" image capture of SRO from the ISS in the afternoon of April 04, 2010:

The image to the left was taken from the ISS as it flew over the Sierra Nevada Mountains. North is up and east is to the right. The direction of travel is from left to right. One of the open window covers of the cupola can be seen in this image. The image on the right is from Google Earth of the same orientation and at about the same image scale showing the backbone of the Sierra Nevada Mountains.

Construction Project updates is back here.

The field curvature measured here is only 8%. Click on the image for a full resolution view.

NGC 7331: by Greg Morgan 12.5" RCOS

& STL-11K Lum 5.5 hours, notice all the blooming taking place. The ABG trim pot needs to be adjusted on this camera.

This is a test image of a 30 minute sub-frame 1x1 Lum filter. The ABG or gain on the STL-11K is set to high. It needs to be adjusted down to a level where the blooming will not take place.

This is a 30 minute sub-frame of a slightly brighter star. The ABG trim pot has been turned 1/4 turn CCW for greater ABG protection as described here.
