Posted on September 28, 2012 by james

This was my first decent length session with the 10″ dob and a good night for it. Checking Ursa Minor suggested a NELM of at least 5.70, so I shan’t be complaining in that respect, although there was a small … Continue reading →

Cloud Towers

Posted on September 28, 2012 by james

I looked out of the window this evening to see this unusual cloud formation above the northern end of the Quantock Hills. I don’t recall that I’ve seen anything like it before. I can’t imagine that the “pillars” are related … Continue reading →

I almost didn’t post this because I can’t quite believe the results are so poor for the second image, but here it is. I’ll try again tomorrow if the weather holds out. A stack of 60 images, processed from RAW … Continue reading →

These two images were taken from the same imaging run, 60 of 120 images stacked, 1/1000th @ ISO100. The RAW files were processed with PIPP, but I couldn’t get Registax to process the TIFF files produced by PIPP from the … Continue reading →
