BUILDING A SMALL IMAGING OBSERVATORY The key point is to ensure that any sheets/flashing higher up the slope of the roof sit on top of sheets/flashing lower down. This ensures that water drains off the roof rather than running in to the gaps at the joints and getting in to the roof space. Similarly, overlapping at least two corrugations at joints across the width ofthe roof will
PIXINSIGHT DSLR WORKFLOW In fact the noise in the master bias frame is proportional to the number of bias frames stacked. You can plot the SNR improvement (ΔSNR) of stacking one more frame as ΔSNR = √ n – √ (n -1) where n is the number of bias frames. I’ve plotted this below so you can see the direct link between theory and empirical evidence: DIY SOLAR SCINTILLATION SEEING MONITOR (SSSM) DIY Solar Seeing Monitor. In this post, I’ll provide a step-by-step guide to building an inexpensive Solar Scintillation Seeing Monitor. The SSSM is a handy device which monitors the atmospheric seeing conditions during solar imaging.NAVIGATION

The Cygnus Wall is part of the North America Nebula (NGC7000). Â It is a huge cloud of ionized Hydrogen gas estimated to be 1,600 light years away and the location of some intense star formation. The darker region to the right of this image is not the empty background of space; we are looking atContinue Reading

This entry is part 7 of 8 in the series A Small Imaging Observatory In this part of the series, I will cover construction of the roof. This is the most complex part of the structure and it required a bit of trial and error to create something workable. The Roof Chassis There are various options for making a workable roll-off mechanism, but I settled on using V-Groove steelContinue Reading
