Here are some more images I did at Kelling in October, which I finally got round to pressing.
These were done with a 65mm F6.5 quad TS refractor.
The week before the Kelling Heath trip I tested the refractor on a starfield and in one corner the stars were egg shaped. So, I thought, do I send the scope back or do I take it apart and have a play? Yep I took it to bits - changed spacers around, tested with one of these ( http://www.hubbleoptics.com/artificial-stars.html) and after a whole day was finally happy with the star shapes but I did scratch the front lens which I was unhappy about but it does not affect the image.
So the outcome was I changed two spacers around and made up a large O ring for the compression lock nut which holds all the lenses together.

I had one of those scopes and mine had pinched optics so it went back, yours seems ok though, nice set of images.
Great images but just one question - why are you using a CLS at Kelling ? It's got to cut you photon capture by half.
Nice work Julian.
Can't believe the TS Quad issues are still not resolved
Some good images there, I particularly like the details you bought out in the Falme nebula.
looking good & nicely processed. The stars in the Horse look a little Cyan (at least on my monitor) but nice - You got a lot of imaging done - John
Gosh Julian, cant believe how many images you got!!!!! you did so well! but you are one of our troupers....
