  1. For Sale: Vixen Advanced Polaris Altazimuth (APZ) Modular Mount condition: brand new in box (tried out once) price: 389€ + 15,99€ postage (EU-wide)
  2. A very lightly used AZ EQ6-GT mount and tripod for sale. The mount is approx 3 years old and I am the second owner. It is in exceptional condition and as stated has been very lightly used by myself and previous owner. Reason I am selling, due to a change of job and working away significant parts of the week / month I have no time to indulge in the hobby at the moment. The mount comes with all the usual items, Mount and tripod, hand controller, cigarette power lead, eqmod usb lead, manual. Also included in the sale is the ADM losmandy / Vixen saddle and the regulated power supply - this one as per FLO website - Nevada PS-08 PSU Price is £995 ovno for everything. I have the box for the mount with original packaging but not the tripod, hence this is pick up only or can travel and meet half way by arrangement - I travel extensively so I'm sure something can be arranged. I accept cash, cheques and bank transfer (which is easiest to be honest). Paypal if the buyer pays the fees. The mount is currently in my observatory and can be seen working if you wish. The ES102 pictured is also for sale in the next ad! Thanks for reading and if you have questions please PM me and we can discuss in more detail. Neil.
  3. Hi, Last night when we was out in the night to do astro photographing I got problem with my Star Adventurer mount. The friction coupling in RA axis got stuck and I have difficulties to aim the camera to the object. Today I have dismantled the mount to find what the problem is with it. I got to repair it, I took photos from my disassembling and repair that I think can be interesting for others to look at and read. Here is the link to my homepage: http://www.astrofriend.eu/astronomy/projects/project-star-adventurer-part2-repair/project-star-adventurer-part2-repair.html Have any other of you had a simular problem with the Star Adventurer mount? BR Lars
  4. Hi All, So I am new to astrophotography and was looking for some advice on what to buy, mainly the mount as I don't have a huge budget. I am currently using a SkyWatcher 102mm Telescope (500mm Focal Length) with a Canon 550d along with a EQ2 mount, so no motors as of yet. Any advice on what mounts to get would be great. Thanks
  5. I see there is now a firmware upgrade allowing the az-gti to be used in eq mode . this is exciting for me as i have a staradventurer as well and could use the wedge from it with the az-gti to have a full goto eq mount has anyone done this yet?

    Backlash Killer

    Hi all, Pretty often I read about people having issues that may be related to backlash in DEC or RA, and I would like to offer a very simple and effective cure for it. I have done it on my HEQ5 Pro but surely it can be modified for any mount that needs it. With this simple fix, I can live with a rather big backlash (with no risk for binding in freezing temperatures). For DEC, I always balance carefully (neither front nor back heavy). Then I stretch the coil spring until it has a small impact on the DEC balance (and later in the evening I eventually forget about loosening it when I slew away... so you will need some replacement springs. It took maybe 10+ of such mistakes until I stopped forgetting...). The bracket is only attached with double sided tape (on three sides), but the black maintenance plug (not original) also supports it. RA is usually OK with just the standard method "East Heavy", but occationally the scope is poing due west or east (counterweights pointing north) and then there is no "East Heavy" impact. That is when I use this: It´s a little hard to see in the pictures, but I get a momentum in RA (in reverse to tracking direction) when I tighten the string. Now, I happen to have the Rowan belt mod which includes a thick nylon spacer inside the gear cover, and that is a good thing here because it adds to the momentum. I usually hook it up an hour or two before the CW bar points due north. Then when it has well past north I will stop the camera, remove the backlash killer and re-adjust "East Heavy". EDIT: (Sorry, English is my second language...) Should be a torque, not momentum. Ragnar
  7. Hi all, I've made a video on how to setup an equatorial mount. Hope this is useful, tips are welcome! https://youtu.be/clNITffWijg

    Dob goto base seized

    Hi, I have a Sky-Watcher Skyliner 300P FlexTube GOTO which I am enjoying however after a period of no use the base has become very stiff. My fault, as it became wet not realising that the cover I had bought for it was not waterproof. Looking through the threads in here I found one which I followed to try to strip down the base however I have become stuck at the point of trying to remove the motor housing from the base after removing the 4 machine screws. I suspect that it is a combination of corrosion and the base material swelling which is preventing me from removing the motor from the base. When I release the worm gear from the static gear using the release lever the motor turns easily which is what is fuelling my suspicion. Any advice or suggestions would be useful as I've come to a halt in my investigation for the moment. It looks to me like I'm going to need a new base which may be a better bet anyway as the original supplied is heavy and definitely not good in the damp. Dom
  9. Hey everyone, So I have just purchased a skywatcher HEQ5 pro mount and been a bit lost with what I need to safely power it from mains. I have been reading different forum post and gotten a bit lost. People are saying you need to regulate it to make sure that too much power doesn't get drawn? Would this just be a normal surge protection plug adapter? I will be using my scope at home for the moment so just want to hook it up to the mains. I was looking at buying one of these -https://www.amazon.co.uk/JOYLIT-100-240V-Switching-Adapter-Flexible-12V-5A/dp/B01LYBUO16/ref=mp_s_a_1_4?ie=UTF8&qid=1533215373&sr=8-4&pi=AC_SX236_SY340_FMwebp_QL65&keywords=12v+5a+power+supply&dpPl=1&dpID=51BeVSM6HKL&ref=plSrch Is this ok? Alot of forum recommendations point to Maplins products however since they arw nowclosed I'm not sure what other places to look for power supplies. Any guidance on this would be much appreciated. Thanks, Matt
  10. Last night I finally managed to get out and have a go at tracking for the first time with the SW SA. DEFINITELY need a ball head... Once I figured out that I should be leaving the latitude adjustment alone (yes I'm THAT much of a noob at tracking and polar alignment), about the only target in my FOV was M31, and even that was about to vanish behind a roof! But I did manage a few 30 second subs before it disappeared. Could've probably gotten longer exposures but the intervalometer wasn't setup and I was out of time. But I'm happy enough for a first time out. The attached is just the test image from last night. About half a dozen subs, Canon 550D, ISO 3200, F/4, cropped down from 55mm Oh, I did notice that whatever way up I put my PA scope, it was upside down...any ideas?

    Best Grease for Gears?

    Hello everyone! i am wondering if it is time to grease the gears on my Vixen GP mount, i have never done this on any mount, upon dismantling the SM control i see it has some grease, not much at all. The grease is greenish in colour and very thick, more so than honey, if i were to regrease it do i need to remove the existing grease? and what type of grease would be best?
  12. Hi all just a quick if you had a choice of mounts would you go for the Skywatcher EQ5 or the Bresser messier EXOS 2/EQ5?. the Skywatcher is about £100 less.
  13. A bit ambivalent about this as scopes come and go and a scope may come in the future resulting in seller's remorse, but here we go! For sale is a Discmounts DM-4 as follows: DM-4 Head 4" Tilt-in Saddle-3 4" Dovetail Converter Universal Angled Handle (shortened a bit as it was too darned long!) 4K Encoder Kit 4" Tilt-in Saddle-3 GRAB & GO BAG FOR DM4 DM-4 8" Tripod Extension Priced new these are (prices shown on Discmounts website) $1,555 + $190 shipping and insurance cost (took this from the invoice that Charles sent me) = $1,745 At today's rate it is £1,245 + VAT (ours is 19% so I will use ours to show my actual cost, not yours which is 20%) £236 + Tariff code 90058000 on telescope accessories of 4.3% (not applied on shipping) £48 = £1,529 which was my cost and the cost you would suffer (well, just a bit more as your VAT is just a tad higher). I am willing to part with it for £1,050 and I will throw in a Nexus II so that you have use of the encoders (if you don't "know your way around" or you are in a light polluted environment) which costs $199 + shipping + above taxes or about £185. Price includes shipping with full insurance and tracking via EMS (takes about 4 working days to hit your local post office) and PayPal fees. I will only accept PayPal (best for the both of us). Dropbox link with some photos here: Dropbox Link I may be willing to sell the tripod if someone is interested. It is the Sirui 5214X and if you grab the package above, I will toss in the tripod at less than half the price of Amazon. Amazon charges £799, I'll sell for £350. Tripod not sold separately unless mount sells first and kindly note that the photos include other equipment which do not form part of this ad and are not for sale. Prices are not negotiable as they are already quite low and also because I know that I will live to regret it when I decide in the future that I want yet another scope for which the DM-4 would be perfect... Here's your chance to grab a premium mount that can lift (and has according to various photos you can find on the internet) up to a 5" refractor (I have seen photos of it with a AP 130 and I tested it with my FS-128 and I only had to be a bit careful changing eyepieces because of the scope's length!) at a competitive price. I have had this setup for a year but used it sparingly (a total of 5-7 times?) as two months after purchasing the mount and tripod, I purchased a FS-128 and a AYO DIGI II mount and well, I love the FS-128 Clear skies, Nicos

    Mount encoder fix?

    My Orion Starseeker IV mount has recently started acting weirdly in that it will continue to spew even after the movement buttons have been released, this will then render all buttons on the handset useless as nothing will work until it is switched off and on again. I contacted Orion and they claimed it may be faulty optical encoders but they haven’t yet replied on how I can fix it and I don’t really want to pay too much to fix it. Does anyone have any ideas on how I could fix it myself?
  17. This was bought new back in 2014. It was used for a short time in our observatory before we decided to get a Mesu 200 in late 2015. Following that, it received little use – we would occasionally get it out for visual work. Further purchases have meant that the CGEM is now not being used at all, and it is time to shift it on. The CGEM is, in most respects, equivalent to an EQ6, although you should be aware that it cannot be used with EQMOD. It comes with the original tripod and a 17 lb counterweight (as shown in the photo). It comes with the 12V cigar plug power cable. • Payload Capacity: 40 lb (18.14 kg) – visual • Computer Hand Control: Double line, 16 character Liquid Crystal Display • 40,000 object database with over 100 user-definable objects and expanded information on over 200 objects I kept the original foam for storing the mount, but the original box has gone. The total weight of the package is not far short of 80 lbs. I don’t know how much it would cost to ship (or quite how I would ship it), so I think collection would be required. I don’t mind driving a reasonable distance to deliver or exchange (maybe we could meet half way). Note that I am also separately selling a Sky Q Link which works with this mount and enables you to control it using an IOS or Android device. £580 The mount is also for sale on UK ABS

    Took the bull by the horns and done the power modification on my Eq6 pro to connect via the 2pin connector , bit nerve racking haven’t really done much soldering before ,managed to do soldering without frying anything, used Blu-tac to isolate surrounding area so I didn’t solder anything I shouldn’t have , mount powered up checked slewing with handset , steady red light voltage reading 14v dropping to 13.9v slewing phew
  19. Hi, I was asked on a Swedish forum to put an "Astronomical Dictionary" on my homepage. I have made a test page in an easy form. Astronomical related words linked to wikipedia. It aims to the beginners in astronomy so it should not be too complicated words. http://astrofriend.eu/astronomy/astronomical-dictionary/astronomical-dictionary.html Let me know if it's useful and and I shall add more words. /Lars
  20. Well, I was finally able to put the newly repaired Sphinx through its paces over the weekend, Saturday night turned out a bit of a bust weather wise, however it gave me the advantage of already being set up for the following evening which was a completely different story. Sunday...? Transparency not all that great, (perhaps NELM variable 3 to 5) and with a half moon shining, not ideal conditions for deep sky observing, however was still able to bag a few old favourites, including M53, M13, M92 and M51, M81 & 82. Then spent the next two hours exploring some galaxies in Canes Venatici, Coma And Virgo. Managed to pick up M63 - The Sunflower Galaxy, NGC 4565 - The Needle Galaxy, M64 - The Blackeye Galaxy, M104 - The Sombrero Galaxy, NGC 4631 - The Whale Galaxy, NGC 4559, M84 and M86 from Markarians Chain, The Leo Triplet and M87 - Virgo A, plus a whole host of other NGCs. Not much in the way of detail, (mainly due to variable conditions), they pretty much all lived up to their names as ‘faint fuzzies’, but nonetheless a most rewarding couple of hours. The Sphinx performed spectacularly, with each goto resulting in the target well within the FOV. The most gratifying aspect of the evening was the integration of the Avalon X-Guider into the ensemble, getting the main scope and finder dialled in is just so much easier now. Also the laser pointer performed its function perfectly as well, that being to improve efficiency of initial star alignment. All in all a most enjoyable two hours or so of observing. Date: 2018 03 25 22:00 to 00:00 Wind: None NELM: Variable 3 to 5 Seeing: II Antoniadi Restrictions: 1/2 Moon to SW Scope: C8 EdgeHD with modified longer focal length due to 2” Crayford and Diagonal. Aperture: 200mm FL: Approx 3200mm FR: F16 Eyepiece: 22mm T4 Nagler: Mag: 3200/22 = 145 AFOV: 82 Deg TFOV: 34’ Exit Pupil: 22/16 = 1.3mm

    Mirror mount

    I have a pair of 15x70 binoculars but due to neck problems I am struggling to use them even when tripod mounted. I am thinking of making a mirror mount but I don't know if they are any good? Can someone please advise me on which mirror I need, size and thickness, fixing method etc.? Do they suffer from dew problems in the UK and if so is there an effective way around this? If anyone could advise me on this it will be very much appreciated. Thanks
  22. Due to recent equipment upgrade, I am selling my Sky-Watcher AZ4 mount including stainless steel tripod. The item is used and has some scratches, but is fully functional. I'm looking for £80. Collection only from Cambridge, due to size and weight. Thanks for looking, Piero
  23. Hi, A polite appeal to the collective wisdom of SGL to get my HEQ5 mount back together again correctly... I was trying to install a counterweight extension bar to my HEQ5 mount (it doesn't fit, but that's another story) and once I'd unscrewed the bar from below this little piece shown in the photo below dropped out. Does anyone have any idea where it's supposed to go? Any info is very welcome before I throw the offending part away and pretend it never existed. Many thanks, Jason

    CGX Noise

    Can someone please take a look at this video and tell me what they think.I've got a horrible noise coming from the Dec motor only in one direction.https://youtu.be/4E-oRAANk_QThanks!
  25. Hi, I’m looking for some help in deciding on a new portable premium mount for Astrophotography. Currently I have a modified DSLR in use (also have a Starlight CCD boxed up waiting to come out to play soon). I’m no stranger to premium mounts having owned an AP1200 in the past. I’m looking for something that can handle a small refractor and APM 152 f/8 Refractor (yes I like refractors) - one at a time, so probably looking at around 15kg payload with cameras etc. Extra spare capacity is welcome for possible future use. Prime use will be imaging and I want something that won’t take much more than 30-40mins to set-up and get running with tracking capable of say 10mins unguided (I may look to do guiding at a later date perhaps with an OAG or ONAG (just to eliminate flexure as much as possible). I want the mount to be reliable in operation and set-up in order to maximise the few opportunities I have to get to good skies. On that subject I am based in the Midlands of the UK, so skies locally are not the best, I can get to better skies in 30mins or good to very good in 90mins or so. Also I’ve never been a big fan of taking a laptop into the field, but if I’m to get using my SXV CCD Camera again I will need to, so it’s not the end of the world if I need to do that (just need to figure out how to power it - any suggestions). Also it may be that I can’t get the best from the mounts without a laptop (MacBook - can run a Windows VM in Parallels) or tablet (iPad). So my short(ish) list has ended up as follows: Paramount MyT - lower than 10Micron on capacity and MUST have a laptop/tablet connected to work (see above), well established company and great software suite which supports Mac (not sure the SXV-H9 works with the camera addon though). Plus it’s a lovely red colour… lol. 10Micron GM1000 HPS and GM2000 HPS UP - (do I really need Absolute Encoders and to spend the extra cash, will I really benefit). Supposedly great unguided capabilites due to it’s modelling abilities. AP 900 - while probably on the edge of portability, these seem difficult to get second hand in the UK. AP Mach1 - very tempting now, considering the 30kg capacity. I have also looked at the ASA DDM85 (too expensive), the Mesu 200 (doesn’t look very portable). I have read and researched for months on this topic, so I have seen good and bad reports for just about all mounts, but I need a balanced opinion (if possible) to help me make my final decision and place an order. Right now it’s really between the MyT and 10Micron, but not sure if I can justify the extra for 10Micron considering how many clear nights I get and how many I can get out on. I am aware I may need to make some sacrifices to get what is suitable to me. Any comments would be greatly appreciated, especially if you have first hand experience with these mounts. Thanks everyone, Mark (desperate to get a new shiny mount).
