  1. Some very useful replies here, Thank you, I may well go with the 70ED and find a small guide camera for it .
  2. I do have a Skywave 70ED Scope which I could use as a guide scope, but I would prefer something lighter
  3. I have a Skywave 102ED Scope and 2 mounts, iOptron IEQ 45 and Celestron AVX Pro, What I need is a suitable Guide Scope/camera bundle to use on this set up. I have been recommended the Starwave 50mm Guide Scope & GPCAM Mono Guide Camera COMBO from Altair Astro, but the specifications say it is only good for 500mm scopes , As my Scope is 715 mm fl can anyone recommend a suitable guide scope /camera combo for my set up. UK Markets only of course Thanks in anticipation
  4. This is an extract from the AVX manual, I think this is what you require oTa orientation – Some users may wish to use an optional tandem bar adapter which allows you to attach two optical tubes to the mount at the same time When most tandem bars are attached to a mount, the optical tubes are positioned at a 90° angle from the standard con guration In order for the mount to be successfully aligned with the stars, it must know that a tandem bar is being used and in which direction the optical tube(s) are positioned (East or West) when beginning an alignment The tandem option must be set before beginning any of the initial star alignments To set this option, go to the Scope Setup menu, select the Tandem option and press ENTER Then select from one of the following options: • east – If the attached optical tubes are facing towards the east when the declination index makers are align, select East • West – If the attached optical tubes are facing towards the west when the declination index makers are align, select West • normal – If the tandem bar is no longer being used, select “normal” to turn off this feature Meridian – This feature instructs the mount on how to respond when it is slewing to objects that are accessible from both sides of the Meridian The Meridian feature allows the telescope tube to remain on a desired side of the mount when slewing, and continue to track according to the R A slew limits the user has set. See R.A. Limits below. The Meridian feature allows for four choices: • Favor current – Allows the mount to favor whatever side of the mount that it is currently on when slewing to objects close to the Meridian For example, if your R A slew limits are set to allow the mount to track 10° past the meridian, then the telescope will continue to stay on its current side of the Meridian when slewing to objects that are as far as 10° beyond your Meridian • Favor West – If the target object is accessible from both sides of the mount, selecting “Favor West” instructs the mount to point to the object as if it were on the west side of the meridian The optical tube will then be positioned on the east side of the mount and pointing west • Favor east – If the target object is accessible from both sides of the mount, selecting “Favor East” instructs the mount to point to the object as if it were on the east side of the meridian The optical tube will then be positioned on the west side of the mount and pointing east
  5. I have got filter threads in the nosepiece of my 2" diagonal, I just screw the 2" filter in there, Guaranteed not to get hit by any eyepiece.
  6. This footnote is on 365s page for the BST EPs These eyepiece are being sold under various brand names like BST Explorer, BST Starguider, Olivon, Astrotech
  7. I have given up on the Watec , and are going instead with this Mintron 72S85HP-EX Colour Astro Video Camera Kit with USB Adapter, from 365 Astronomy, Zoltan, the owner of 365 is a personal friend and the camera comes recommended by him. Unlike the Watec the Mntron is colour and quite a bit cheaper so as I already have 3 canon DSLRs , 1 Astro modded Canon 60DA , the Mintron will suit me as an entry into Video
  8. The advert gives optimum magnification as 225x and maximum magnification as 675x , that is a load of rubbish, With an 80mm scope the optimum mag is 160x in very good seeing conditions, Don't be taken in by this sort of sales hype, Suggest you try a proper astro dealer
  9. Thanks Paul, will look into that Graham
  10. I should add that with the exception of the Meade LS 8 other scopes will be on a Celestron AVW mount
  11. Having been a purely visual astronomer for some time now and wanting to get into AP, I have decided to go the video route ,,I am interested in the above camera, have read the spec, and am considering purchase, I would be using it on either Skymac 150 pro, SW Evostar 150, Mead LS 8 sct or Starwave 102ed frac, Has anyone any experience of this camera or could suggest a better buy, You're observations appreciated Gray
  12. I have an Ioptron IEQ 45Pro mount. The saddle width is 76mm . I have recently purchased 2 Altair Astro Losmandy Plates, 180mm to fit on my Altair Skywave 102 ED and Skywatchers ST 120 Scopes. As recommended by Altair Astro, On fitting the scopes fitted with the Altair Losmondy plates, they slid right through. On measuring the Altair Astro Losmondy Plates I found that they were UNDERSISED by 1mm, and we're in fact 75mm width . I also have an Ioptron Mini Tower the saddle width is 75mm.minimum, The Altair Astro Losmondy Plate supplied is 75mm It fits, but with the slightest ware will slip. Have anybody else had any problems with Altair Astro plates being either undersized or just at the limit to give an initial fit not allowing for wear and tear
  13. I am a member of the Meade users web site and have just posted a request for Meade to update me on them current situation, They still have Meade Europe dealers but we do really need a UK outlet
  14. I personally would not consider the Celestrom Astro Master 130 for AP, It has a lot of plastic fittings and the mount in not very stable, ( I know because my son has one). It will not really take the weight of a DSLR camera without a lot of shake. A better bet , if you want to go along the Newtonian line , would be a SW Explorer either the new 130 Pds or the better 150 pds , both are optimised for AP, Both scopes are getting some good reviews on several Forums
  15. I have given you some advice on the other Forum you posted this request on
  16. I managed to get 12 pucks for £18 + £2-95 P&P, Just need to grind a small dip in them for the mount feet Graham
  17. I have been looking around for a set of these pads , and cannot find any under £50-00 a set, but whilst trawling through Amazon I found that I can but Ice Hockey pucks from between £1-30p to £4-00 each, They are made from Solid Galvanised Rubber so must work as well as the Astronomy pads , and are a lot cheaper, What do you think Would they work ?? Graham
  18. Meade has had quite a bad reputation of late as far as customer satisfaction and relations are concerned, and have had some bad reports in several Forums . Whether or not this has put people off buying their products remains to be seen. I have a Meade LS8 ACF which did fail on its auto align system, but my importer replaced the scope under warranty and the replacement is working very well, so I cannot fault the Meade dealership in the UK, My LS8 is F10, a normal focal reducer which includes a field flattener is not suitable as the scope has ACF , I use a standard 0.5 reducer which screws into the diagonal or camera and gives me F5. For visual along with a wide EP the views almost match those in my F5 frac , I have not attempted AP with the LS8 yet as I am awaiting delivery of a canon 70D , I admit the LS is not really suitable for AP, but I am going to give it a try.
  19. You have a local society Hants Astro try this link www.hantsastro.org/‎
  20. There is a complete series of videos on U-Tube made by Astronomy Shed that cover everything from setting up and Polar Aligning HEQ5 and 6 mounts . Just type in Astronomy Shed videos sit back and learn
  21. You may find this link helpful http://www.csgnetwork.com/telefov.html, gived mag ,AFOV and TFOV for scopes of varying FL and different FL eps, As a suggestion for a not expensive but good EP, look at them result for the Celestron 32mm ep. AFOV is 46deg, mag 19x and a TFOV of 2.45 , I am thinking of getting this one for my ST120
  22. I have a SW 120ST, and for observing I dont worry about CA , different for imaging though but I fit a semi APO filter and that reduces it a fair bit, , As far as a wide angle ep is concerned, My Meade 26mm gives me a mag of 23x , field of view of 2.26deg and exit pupil of 5.2mm, I also have a 40mm EP but the exit pupil is 8mm far too wide for by 66 yr old eyes and fov of 3.46
  23. Thanks for that , It looks like the ED80 in on the cards,, and also a big saving against the ED100, Now to research those cameras,
