Hi,
Just thought I'd share this technical experience.
Last night I was doing a quick session with ye old telescope between the clouds. I decided not to collimate the LX90 but just got stuck into some visual stuff. M57 check, M27 excellent, m13 wow.
So In I trot to get the SAC8, set it up, took some images through the refractor, Moon wee, then M13 with a 2x Barlow.
So, I thought, what the hell its only 11pm, I put the focal reducer on, whacked the telescope on vega and focused.
Strange, the rings looked like they have a flat tyre. Take out SAC8, look down the hole, looks fine. Focus in out, shake it all about and nope, still looks like a flat tyre, at this point I thought sod it, I just got the focus as good as I could and took a set of M57 wide field images (not as good as Paul's but he).
So then the clouds came in and I packed up.
It was at this point I noticed the glue holding the Velcro on the dew shield had come loose and the thing had changed shape.
Cunningly the dew shield had changed it shape to a flat tyre. Hmm.
I can only congratulate BC&F on the quality of the glue they use on their flexible dew shield.
Going out to by some glue today and a new bungee for the dew shield.
One of the small stands at the BAA exhibition meeting last Saturday was a collection of bits helpfully labelled "Blue Peer Astronomy". It included several cardboard and Baader foil solar filters and a dew shield made out of a karri-mat. :wink:
I added extra strips of Velcro on the ETX dew shield as the original ones were crap. I used standard stickybacked black Velcro. Stays on fine now and holds it's shape. It is a lot smaller then the LX90 one though.
So where's the images then Chris? John

Yeah Chris where's the images, Gimmie image gimmie image.
