  1. Just a thought regards earlier post about the camera/usb possibly playing up... I used to use a 550d modded with a 130PDS on an EQ3 Pro a few years ago before I sold the lot to help with costs of our wedding but before doing so and after some frustration with the camera conking out randonly both when just connected and also whilst usong BYE, I discovered that when using a 10 metre USB extension cable for some reason the distance to camera seemed to lower the signal/output and after I replaced it with a usb cord with 'signal booster' attachment (still really cheap on fleabay) the problem immediately went away. Worth a try??! Scott
  2. Cheers James. I have thought of that already - basically taking off a bit at a time so I don't go too far. I guess I'm just looking for a solid start point as it will need to be a precision job and the more times I have to cut, the more times I can [removed word] it up
  3. I always found trying to focus with a DSLR/lens very finnicky. I also found that setting the lens to 'infinity' very often was not 100% accurate. Best advice I can suggest is turn AF off and just use manual focus, set to infinity and be prepared to adjust the focus ring a tiny amount each time. I once used a 70-300 on a Pentax DSLR and ended up making my own Bahtinov mask to achieve focus but even then it was a faff. You might struggle with an 18-55 unless you can zoom right in on live view?
  4. Hello all. As a lifelong stargazer and previous participant in the great halls of SGL, I have returned to the fold and very quickly encountered an 'issue' I'm hoping to get some kind advice on please?? So firstly...hello again everyone. It's nice to be back I took a couple of years away from this brilliant hobby fully intending to get back in again when the time was right. Well, in January I was involved in an accident and had a serious leg fracture. I treated myself to a fairly cheap, but enjoyable Celestron LCM 80 to do a bit of visual from the confines of the back garden whilst mincing about on crutches and one thing led to another... I have since added an ST80, all manner of EP's and bought a cheap but strangely enjoyable Bresser Skylux 70/700. As a previous practicer of the dark arts, I ended up adding a camera into the mix and have taken some half decent 30 sec subs & got some pleasant enough shots of a few DSO's. Now, my problem that I'm hoping to get some tips on is this... I've decided to cut the Bresser down a bit. I have an Orion flip mirror (mirror box is 3 inches long) and when rigged up, all is within the weight limit of the LCM but I just don't quite have the inward focuser travel needed to bring the EP/camera to focus. I reckon a bit of careful cutting of the optical tube will do the trick, but my query is this. If I'm about 1" shy of focus with the flip mirror, can I take off 4 inches without ruining the scope?? I'm thinking the length of the mirror box will cancel out the shortening of the OTA and the extra inch will allow the whole thing to focus with minimal outward travel - keeping it stable. I've already cleaned & blackened the lenses and modified the rack & pinion to make it stiffer, more stable and generally better to use. I know there is maths involved but rather than give myself a headache, I thought I'd come to you guys again. And before anyone laughs about using the LCM for AP, having been the proud (and sometimes frustrated) owner/user of an autoguided EQ rig before I know what the LCM mount will and wont do, and its surprisingly good fun getting some 30 sec subs with a rig that takes me about 3 minutes to set up and take apart. All suggestions welcome. And it's good to be back. Clear skies Scott Cloudy Stoke on Trent
