  1. Wow so my new scope arrived and I was running through all the different options for guiding. I thought I would share my experience and hopefully other beginners might find something useful from this. I purchased a skywatcher evostar 80ED Pro with a HEQ5 Pro mount and it came with two green dovetail bars. I already had an ST-80T that I wanted to mount on top but the “dovetail bar” that came with that was a small useless plastic block. The biggest, most annoying hurdle with this process was that on each dovetail bar, there were metric- and whitworth-threaded holes, with different diameters. What I ended up doing, was taking off the evostar dovetail and attaching that to the top of the evostar scope rings. This was important because this dovetail bar has a slot in it, that allowed me to correctly space the guidescope rings. I only had two whitworth bolts (fortunately that were quite long and had nuts with them), but I used each of those to attach the dovetail bar to the top of the evostar rings. The whitworth bolts were both cut down to size, and the spare part of the thread was used to attach one of the guidescope rings to the top dovetail bar. Note that I had to drill out the thread of the ST80 rings, as they were metric threads, where as the dovetail had whitworth threading! I screwed the length of whitworth bolt down from the top and used the nut and a small washer to tighten it down. For the second ring, I placed it in the slot of the dovetail bar and used a small length of metric thread, that I could then bolt from each side (effectively clamping everything together). Finally, I attached the dovetail bar that came with the HEQ5 (I think it might be the standard, medium dovetail bar that you can purchase separately), to the bottom of the evostar rings. I think I used the bolts that were originally in the bottom of the ST80 rings to bolt those down, and then added in the lateral screws to make sure the rings couldn’t rotate. It was considerably harder work than it needed to be but I am pleased with the results. It cost me nothing but time and a bit of effort. I know that the guide rings don’t have adjustment bolts, but at least with the current set up, there is no determinable flex, and with an 80mm scope, it shouldn’t be hard finding a guide star. I am a fan of having the matching green dovetail bars. And I have attached the guide camera and DSLR and can perfectly balance the mount. So overall, a great result.
  2. This is a very nice Lumicon 80mm mega finder or potentially a rich field scope. Optically it is in excellent condition and cosmetically very good too. It has a nice, smooth rotating helical focuser, with locking screw which as a decent range on it. It has a 1/4" photo thread on the base so can be fitted to a photo tripod etc, or adapted to fit Skywatcher show with extra parts. Looking for £90 ono plus P&P via PayPal fees paid or bank transfer. Will include a basic Skywatcher RACI Prism for another £10 Also advertised elsewhere.
  3. At last! A bit of weekend reading for y'all at http://binocularsky.com/binoc_reviews.php Summary: Darned nice binocular. Big, flat, bright field. Weighs less than the Helios Apollo 15x70.
  4. As per the title I am looking for a Skywatcher Startravel 80mm or 102mm optical tube assembly, needed for a project. Cash waiting for a sensibly priced example in good order.
  5. I kinda "force" my Astrotrac with my 102ED on top so I'm out shopping for something more appropriate... an 80 mm FPL53 is a must for both doublet and triplet. It will be used for astrophoto and visual g'n'g. After tons of reviews and articles I came with a very shortlist. And here comes my indecision, since the tubes are more or less "identical" but labeled by different companies. -triplet represented by Orion ED80T CF Astro-Professional APO 80 Carbon TS 80mm f/6 (not Carbon) Tecnosky Triplet FPL-53 APO 80/480 -doublet (more or less alike) made by TS 80/500mm Altair Lightwave 80mm F6.25 The budget is 1000$ (~800e) not a cent extra Altair Lightwave doublet and AstroProfessional triplet are my favorites, but can't decide which. thank you
  6. Work in progress for now, just sorted the correct spacing for the flattner & the stars need sorting with the correct data. AZEQ6 mount, AA 80mm EDT @ 480mm fl F6. Atik 314L+ Guided using the DMK""618 with AA 10x60 finder 225 fl F3.75 Ha - 1.5 hours OIII - 45 mins S2 - 45 mins Just need to find a tut on the best process for adding correct star colours now, meant to be better weather Sunday night as well.
  7. Just purchased a Skywatcher ED80 refractor and apart from the supplied 2" 28mm LES eyepiece I have the Ultrawide 6mm Skywatcher 1.25" and the Skywatcher Super Plossl 40mm. I am looking at purchasing a 2x or 2.5x Barlow and was after any recommendations? Also have I read somewhere that I have to have a certain 'type' for the supplied 2" star diagonal? Would I better be off purchasing one that can fit both 2" and 1.25" eyepieces or for optical quality sticking with just a 1.25" (does it affect optical quality even?) Celestron Luminos for example My other question is can this scope take (visually acceptable) a 2.5mm eyepiece and take it to the max possible magnification if I required max even. Last question is Sky-Watcher SWA 70° Eyepieces on offer at FLO at the moment, anybody have any thoughts or feed back as I was thinking about an Hyperion to add to the eyepiece collection. (thinking about 13mm-17mm) Sorry, a load of questions but I live in West Wales and have no local suppliers within 100 miles, I'm happen to be going past FLO at the end of the week and I've a credit card .....gulp!
  8. As part of the clear out I'm selling my OPticstar AR80s guidescope, it comes with rings and dovetail mounting. Owned from new (3 years) and has been well looked after, however there are the inevitable marks on the tube from the securing screws, purely cosmetic and don't affect performance. I've got this up on AstroBS for the same price £100, will post for small fee Thanks for looking Lee
  9. Hi, I'm looking at getting a short focal length, wide field scope to add to my equipment list if possible. Uses will mainly be wide field visual, some EAA, and a gentle 'dip the toe' into imaging. There seems to be a wealth of choice currently, especially offered from TS and Altair. Ideally looking at the 60 to 70mm offerings from Altair but would consider others. Many thanks for reading,
