Wedges are expensive The weight of the fork and OTA is quite substantial ...Toss in a wedge and the Gem is simply easier to transport and set up That said I have no use for Gem mounts anymore because my old body is not as flexible as it used to be and I have no interest in AP Bob G Post Extras:       tarotmac member Reged: 09/13/12 Loc: Ellesmere Port, UK Re: Celestron C11-SGT (XLT) V CPC 1100 xlt and wedge [Re: Bob Griffiths]       #5523887 - 11/17/12 07:02 AM Edit   Reply   Quote Quick Reply   Thanks Bob, comments duly noted and appreciated Post Extras:       HeyJP sage Reged: 12/11/10 Loc: Boulder, CO Re: Celestron C11-SGT (XLT) V CPC 1100 xlt and wedge [Re: tarotmac]       #5524136 - 11/17/12 10:50 AM Edit   Reply   Quote Quick Reply   Tarot, Here's the way I break it down. The CPC (alt/az) is best for visual observing and quick astrophoto setup for 30 second snaps. Comfortable viewing angles. Less than a minute to align. An EQ mount (GEM or CPC/wedge) is required for long exposure photography and requires polar alignment which is a bit more consuming than a quick align on CPC. I think it comes down to your astrophotography requirements. I tend to do visual observations 90% of the time and some amount of astrophotography. So I just picked up a CPC1100 this summer and love it! I am in the process of picking up the HD Wedge. While installing the scope on the wedge is a bit more pain, I don't expect to do it a lot and having the more portable, quicker setup Alt/Az dominates. But, if you are going to spend 40-50% of your time, or more, doing photography. You certainly might be better off with the GEM mount. My 1.5 cents worth.

With the gem a light breeze won't make it shake at all and can even image in some wind that is maybe up to a few mph. The cpc on the wedge can't image in anything that you can feel because it makes the structure very shaky. With the cpc in alt/az mode you can image in wind that you can feel almost as well as the gem except for the sky rotation. So my vote goes for the gem with the much better bite sized weight sharing pieces. Putting the cpc on the tripod is a bear anyway, add the wedge and it is a grissly bear. Post Extras:       Pages: 1
