If the weights are too heavy to balance the scope you can just move them further up the bar, I've had a 120mm f5 refractor on one - semed OK. i carry my EQ5 mount, tripod and 150mm refractor out in one trip and I'm not a big guy, you just collapse the tripod legs, lift the OTA with both hands you're away. It's the exact same set up as with an EQ3 just a bit heavier. Gaz |

the mount you linked to at D.Hinds is a bit big for your scope (you'll get away with a EQ2/3), but it's a good deal and not any dearer than the smaller EQ2/3 anyway. If you don't mind carrying the extra weight when you set up I'd get it - it doesn't hurt to over-mount a scope and if you wanted to get a new scope in the future a bigger mount would give you more options. Thanks for the advice, Gaz, I think I'll go for it. The link looks great, even if it is over there Can I ask why you just didn't sell the Nexstar 5 secondhand and buy a equatorally mounted scope with the proceeds? I don't know what they go for these days but it would seem the be the easiest (and cheapest) option? Your easier option isn't easier for me. I had the scope, which I like, all I needed was to remount it, once I'd found out how to remove it from the mount. Transportation is a bit tricky in a top box, there aren't any shops around here, and visits to CPAC hadn't helped as they were always busy. I didn't want to sell a mount that I personally had found horrible - I know it's not down to me, but still - I didn't want to try and find a buyer and "sell" it, it's not my sort of thing. And p'raps no-one would want it: if they asked *my* advice, I'd have to say "don't do it". I only raised it in this ng because I couldn't work out how to remove it, but breaking a bit of plastic (God knows what size hex keys Celestron use) made it all a doddle. Then I was worried about getting rings; I haven't a clue whether they're highly engineered, or adjustable, but it seems athat a dovetail will do, and prolly all I need is a specific C5 one, only a bit of pierced metal, can't be more than 350 squid from Celestron... Anyhow, it's not my style to be optimistic, but with a bit of luck it'll work out.. mike mike |

Mike, I think you'll be presently surprised by the cost.... All you need is the mount (=A3130), a dovetail (=A315) and two tube rings (about =A330 the pair). The dovetail attaches to the mount, the rings attach to the the dovetail and the scope goes in the rings.....voila! You're done! Gaz |

Some incarnations of the C5 OTA (e.g. the C5+ and the G5) have a dovetail; I *think* (but am not certain) that the same holes are used for mounting the N5 to the Nextar mount.

Yup - EQ3-2 is what I meant (lysdexia again...). Also the £100 difference
shows on another website (venturescope). For £129 the CG5 offers excellent value in comparison to alternate offerings (@ £295.00). I'd not noticed the 'special' price.

: They are usually dimmable with the rotating on-off switch -- rotate it to nearly off. Have done, still way too bright. The only time it's ok is when the battery's on it's last legs. and on a faint star, like Polaris ;-) I can't quite see through it. Use both eyes and superimpose images of dot and target. Tried that too, a combiation of pollution and old eyes makes it hard. I can't always see the full W of Cassiopeia. Thanks for the earlier comments re the tripod/mount; and I think you are right about the rings - the starfinder is mounted on a dovetail; it looks as if it's specific to the scope. The pictures I've seen look as though the scope mounts on that, so I'll be able to work with 2 dovetails or a set of rings. The pount comes with a dovetail, which is confusing, as the dovetail appears to fit the scope, not the mount. Guess I'll just have to get one and suck it and see mike |

With the Hinds offer you're are pretty much getting a EQ5 for the price of a EQ 3-2, so it has to be a good deal! It's true you don't need the tube rings? I've never used a C5 so I was kind of generalising with the set up, but my point was Mike won't need to spend =A3350 on the set up.=20 all the best Gaz |

For £129 the CG5 offers excellent value in comparison to alternate offerings (@ £295.00). I'd not noticed the 'special' price. Regards Chris Yes. I can confirm, that a short dovetail, is available directly from Celestron, to screw onto the rear cell of the scope. It is only about 5" long, and bolts directly onto four holes in the cell. I think it was about £8. The CG5, is an excellent mount for the C5. The only 'caveat' with it, is 'goo'. In common with most of the manufacturers of the clone mounts of this sort, the far Eastern company who put this together for Celestron, seem to have shares in a company selling extremely viscous lubricants. The result is that in colder climes, it can be over stiff. Taking the mount apart, is not hard, if you take your time, and stripping this goo off, and replacing with either a Lithium based grease, or one of the PTFE lubricants, can improve the mount massively. There are a nunber of 'variants' of the CG5. The original, was an almost direct clone of the other mounts like this. Then it was improved by adding ball bearings on the RA axis. Then more recently still, ball bearings were added to support the worm. The original variant, is like a cheap Vixen GP, and with care can work well. The 'middle' variant, has more load carrying capacity, but suffers from having a rubber 'O' ring at the end of the worm shaft, making it almost imporssible to get backlash down to sensible levels if this capacity is used, unless this ring is replaced with something stiffer (nylon). The last variant, can perform very well indeed. The last variant, also has slightly 'better' lubricant selection than the earlier mounts, but still stiff enough to be 'annoying'. For the price being asked, this is a great combination. Realistically, the CG5, is not 'big for the scope', the weight difference between this and an EQ3-2, is very small. Generally the load capacities quoted for mounts are always on the 'generous' side, and while some combinations do get 'silly' (A Borg 76ED, on an AP1200 for instance), I'd always say that a slightly heavier mount is the best way to go, _provided it is not too heavy to comfortably use_. The CG5, is a very easy to handle mount, and should not cause any problems in this way. :-) The fact there is some 'reserve capacity', could be useful in the future.
