  1. I have done the same with my 're-modded' Meade ETX105. It opens up a whole new world!

    Meade etx parts

    Just an update to my previous post... Reason my ETX105 has an aluminium backplate instead of the usual plastic one is because the OTA suffered a fall from one of my mounts and damaged two mounting points. Meade and their agents/resellers did/do not keep spares. My insurers, (at the time), were offering me a lot less than the estimated value and I did not want to see my ETX end up in a Thames Valley land-fill site. Below are links to what was done to resurrect it... (warning: picture heavy). You may find this dovetail bar ---> https://www.firstlightoptics.com/dovetails-saddles-clamps/astro-essentials-dovetail-bars.html ...is better styled/suited for your ETX125 if you do not like my method of attaching the dovetail.

    I hate to be the bearer of bad news, but I would be inclined remove the OTA from the forks, (i.e. de-fork it), and invest in a dovetail bar and an EQ mount. The drives of the ETX90/105/125 series are/were the weakest link. The images above and below showing my 're-modded' ETX105. The dovetail bar is attached with a pair of neoprene & felt lined Jubilee hose rings and mounted on my Vixen GP.
  4. Hi! ...are there any letters before the numbers on your eyepieces...? (see below) - assuming your 'scope focal length is 800mm, using the e/p with the highest number, (low magnification), working down to the lowest number, (high magnification)... i.e. 25mm (32x) ---> 12.5mm (64x) ---> 4mm (200x) PL = Plossl [1] OR = Orthoscopic or Ortho [1] WA = wide angle [1] UWA = ultra wide angle [1] K = Kellner [2] H= Huygens [2] SR = Symetrical Ramsden [2] RKE = a modifed type of Kellner [3] - used to come supplied with the Edmund Scientific 'AstroScan' telescope. some older types, not shown, no longer produced [4] - occasionally come up for sale secondhand or auction. the exotic names of some eyepiece types, not shown, given by some brands [4], often have wider fields of view, more glass elements, coatings, etc. [1] ...Plossl's and Ortho's are the most popular and affordable types available - good to average eye relief. [2] ...available, but you would be better off buying a Plossl or Ortho. [3] ...still available, [apparently], via Edmund Scientific - good to average eye relief too. [4] ...to many to list/name here. The Edmund Scientific 'AstroScan' telescope --->
  5. Hi Ade. Forgive my ignorance... quote: "Phone is Huawei P20 Android Pie v9.0" - the text I have placed in italic font, is that the version of Android OS or the model number? If "No!" is the Android OS up to date. Sorry but I forget which version it is now!
  6. My budget e/p's for grab & go... I use this 7-21mm zoom and this 18mm via AstroBoot. Also this 28mm via UKAB&S. The 7-21mm and 18mm are OK for terrestrial and white-light solar viewing too... with the exception of the 28mm for solar as it is a 2" and my Herschel wedge is 1.25".

    Help please!

    Hi @HMC and welcome to SGL and congratulations from me too. Here's another for the SkyWatcher Skyliner 150P Dobsonian. If you can afford a bit more, then there is the bigger brother/sister... SkyWatcher Skyliner 200P Dobsonian.
  8. The TeleVue Nagler 3-6mm zoom is perfect in my TeleVue Ranger, (480mm/70mm @f6.8 BTW).
  9. Hi @Sky-searcher and welcome to SGL. Very impressive! Out of interest the 'Vixen' type dovetail does fit some photo/video tripod ballhead saddle plates.
  10. Are you 'prime focus' or 'afocal' ? 'prime focus'... means using the telescope as the camera lens so you will need a T-ring and/or 1.25" or 2" nosepiece if the focusser tube is not threaded. 'afocal'... means using a telescope eyepiece, eyepiece projection unit [epu], and T-ring, therefore magnifying the subject. possibly a Barlow lens or PowerMate for lunar, planetary or solar (see below) imaging. red light/torch. spare battery/batteries for camera & torch, (if not powered via powerbank/external power source). patience. Above is an afocal image of Montes Apenninus using a Meade ETX105, 20mm Plossl in the eyepiece projection unit, (as shown in the first image), and an Olympus C2040 digital compact camera. ================================================================================================ SOLAR IMAGING/VIEWING Never image/view the Sun unless you have the necessary equipment checked for all defects and all safety precautions have been read and understood before each and every use. ================================================================================================
  11. Here's my contribution... my Tele-Optic Giro mkll. I used to have it on a Manfrotto 190 & 055PROB tripods when I first got the Giro... "You're gonna need a bigger boat tripod!" When I got the ETX & C6... I got a 'bigger' tripod.
  12. Hi @NicolaTerry and welcome to SGL.
  13. Hi Gus. May I purchase the Opticstar RDF if it is still for sale? tnx in adv
  14. As per @Gina. The ones I tend to avoid are those where English is not the sellers first language on other sites. Soon as I mention that I am on SGL and they will either reply... or get sucked into some gigantic blackhole if they are not.
