  1. Cheers Alan, I think it might work out well to use the Skywatcher pillar extension on my Vixen pillar for my longer refractors and maybe one of my Vixen tripods with the extension on for my Mak/newt. Some measuring needs to be done.
  2. Thanks @pete_gamby , that looks like it should do the job. I've also been looking at the Orion Optics Pedestal Top to accept EQ5 mount (PADT2) which might work but I'm waiting to hear how wide it is and how low down the 3 threaded holes are. @spaceboy That is a really good idea. I don't know why I didn't think of that myself.
  3. I just bought a Tele-Optic Giro Ercole mount and I would like to fit it to my Vixen P110 GP Pillar but as you can see from this photo the pillar top has a North alignment peg so the Ercole won't go on it as it has no space for the peg to fit into. Does anyone know of a replacement for the pillar top or maybe of some kind of adaptor I could buy off the shelf? I understand I could probably get something turned up on a lathe but I'd rather just buy something off the shelf if I can. Thanks folks.
  4. It's basically a Vixen R200SS on a Super Polaris. I have one myself which is probably a bit newer. Very good telescope for DSO astrophotography as it is fast at f4 but that also makes it difficult to collimate due to the small sweet spot so from my own experience not ideal as a first telescope for astrophotography. You would be better to get an ed80 if that is what you want to do as you will get good results much more easily. If you want to use it for astrophotography you ought to get a bigger mount, an HEQ5 or Vixen GP-DX would be big enough and would fit on the pillar. The skysensor 3 is old and does not support autoguiding from what I remember so not much good for astrophotography of DSOs and if you want to use it for photography of lunar and planetary objects you would be better off with a longer focal length telescope that is easier to collimate or does not require any collimation like a refractor or mak/SCT. The optics will be very well figured and could be as good as 1/10th PV, and the silvering is applied using a vacuum technique that makes it highly reflective and long lasting, similar to Orion Optics hilux. £500 is roughly what the OTA without mount is worth and the pillar is very nice to have so a fair price.
  5. I use a pair of AE binoviewers which are chinese made and almost identical to the TS ones. The thing to make sure of is that you get a set with the self centering diopters as these make it much easier to keep the EPs centred in the binoviewer. Also worth considering is the length of the light path in the binoviewer and the clear aperture in it. I got a Siebert MultiMag OCA 1b from here http://www.siebertoptics.com/SiebertOptics-OCA.html#Ad 1b which allows me to reach focus in all of my scopes with a 1.25x magnification. I use either Vixen SLV EPs or BST Explorers and the views on planetary and lunar objects are wonderful. For lunar viewing in particular I always use the BVs. I can see the full disk of the Moon with a pair of 18mm BSTs and my Orion Optics VX10L which has a focal length of 1600mm, and, depending on how good the seeing is, for higher powers I use either: a pair of Meade 4000 9.7mm for 206x and a 1.2mm exit pupil a pair of Vixen SLV 9mm for 222x and a 1.1mm exit pupil a pair of BST Explorer 8mm for 250x and a 1.0mm exit pupil I have a pair of Meade 4000 6.4mm EPs as well but I find it difficult to merge the images and the magnification is too high for the seeing at my house anyway most of the time. For high power viewing I probably use the 9mm SLVs the most and the BST 8mm the least. The Siebert MultiMag OCA is better quality than the barlows I have used before I got it and I prefer the lower magnification it delivers although it can also give 2x or 3.5x in different configurations. If I upgrade any part of this it will be to send the BVs off to Harry Siebert to get them supercharged so I can use EPs with a larger clear aperture for wider views. I think the low mag OCA is worth having more than more expensive BVs as it means I can use any scope I like with the BVs as long as the focuser will cope with the weight and the chinese ones like the TS are light. I would recommend reading through Harry Siebert's website. Although the appearance of it is difficult sometimes, the info on there about binoviewing and binoviewers is excellent and helped me no end to choose what I wanted. I hope this helps you with your choice.
  6. I'd agree with this. With a 30mm Explore Scientific 82° I can get most of the Pleiades in the field of view through my 1600mm focal length dob, but it is a much nicer view through a scope at 1200mm focal length with the same eyepiece so I can see it all with some empty space round it. That said, even a 2" eyepiece takes up less storage room than another scope

  8. Vixen R200SS 8" F4 Astrograph with Vixen coma corrector. Superb optics. Barely used in excellent condition with original accessories, tube rings, and dovetail. It has Bob's knobs fitted and comes with original collimation screws as well.Collection only from Bristol or I could meet you within a few miles of M4 J20 / M5 J15. I will not send this by courier/post. £550. Payment by PayPal or cash on collection please.
  9. Thanks John. It will be kept in a place which is cooler than indoors and I'm hoping the rear fan will help with cooldown as well. Tony who sold it to me said that collimation of the secondary was tricky as the secondary tends to rotate as you adjust it but that it holds collimation well, and he has collimated it for me so hopefully it won't need doing too soon. I'm really looking forward to trying it on the Moon, Jupiter and Saturn. :-)
  10. @Stu I'm hoping it will be great on the nights when the seeing isn't good enough to get the best from a larger scope.
  11. Cheers, I've never looked through one so I'm hoping for a clear night soon. It will go on my GPDX and maybe my Atlux when I get the pier sorted or a tripod for it. It will probably be the cause of some new eyepiece purchases too, most likely a 5mm BST and 6mm SLV. Yes, I think Intes just make optics for space now, they don't sell to consumers.
  12. I just picked up this Intes MN71 MakNewt and thought you all might like to see a few photos as there aren't that many of them about. It's got some nice baffling, Orion Optics HiLux coatings, rotating rings, and a fan behind the primary which was an optional extra. It's a 7" F6 Maksutov-Newtonian. Apologies for the weeks of cloud we will probably get now.
  13. I have had 2 GPs, the original ones and I don't think you can use them as alt/az but I also have an old Super Polaris which can definitely be used as an alt/az. Capacity is about 7kg I think from memory. I'll check a GP tonight to see if it will go to alt/az if you want.
