  1. I am going to upgrade to the skywatcher 250/1200 pds telescope and i can't decide which mount i should get. The main (only) purpose is astrophtography and i am considering either the eq6-r- pro or the cem60 The cem60 can carry more weight but is also more expensive, my inner debate now is about if it is worth it What's you take on it?
  2. Hello, I have a 4 year old Skywatcher NEQ6 mount that I control with a Synscan hand controller. Recently I have had trouble with the goto command not slewing to and finding the targets despite properly following polar alignment with polar scope followed by 2 or 3 star alignment. I have eliminated cone error, so do not think this is the cause. The RA and DEC motors run smoothly with not much noise. In attempting to understand the cause I noticed that if via the hand controller I slew the telescope by 12 hours in RA; the setting circle indicates that the telescope has slewed by 12 hours 20 minutes, which I can imagine could be a possible cause. Does anyone know if it is possible to perform some sort of re-calibration of the Synscan hand controller to adjust the slewing so that it corresponds with the actual physical movement around the RA axis. I cannot see anywhere how to do this or why it may be out of calibration. Thanks very much for any advice. Regards, Mike (SW France, equipped with Celestron C11)
  3. 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!
  4. Hey guys! Its me again... I know what you are thinking there is not such thing as a cheap mount for astrophotography...and i agree with you! I just want to know if there are any significantly cheap mounts (under 100 pounds) for my skywatcher heritage 130p that can give me maybe 15-30 sec exposure time max. Thanks Kronos
  5. 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
  6. 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?
  7. I'm looking at upgrading my manfrotto tripod to something far sturdier and taller. I'm 6f3" so ideally having a tall tripod makes life easier as long as it doesn't get blown about by the wind. I've heard the eq6 is a good shout but perhaps a little on the short side, but or the manfrotto 055 potentially still wobbly, or vixen porta ii. I'd like to spend less than £60, but is that realistic? What do you use or recommend? Thanks Leon
  8. 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.
  9. For Sale: Vixen Advanced Polaris Altazimuth (APZ) Modular Mount condition: brand new in box (tried out once) price: 389€ + 15,99€ postage (EU-wide)
  10. After being initially excited at getting my first mount. I found that the instructions that came with it aren't much help. I'm trying to use the mount with my canon camera and 70-200 lens. I know I have to align the mount to the celestial pole but do you do this before turning the mount on? How does the mount know if you are using the camera on the left or right side? Sorry for what are simple questions but I feel once I get these sorted I can start enjoying my new hobby instead of being frustrated at the first step.
  11. 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
  12. 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?

  13. 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
  14. 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
  15. 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
  16. Read more and download: http://www.lightvortexastronomy.com/tweet-remote-control.html Tweet Remote Control is a Windows program written in Visual C# 2015, embedding the Tweetinvi and ASCOM references. It is meant to act as an inconspicuous safety backup, particularly useful to those with remote hosting for their astrophotography equipment. The original motivation behind Tweet Remote Control is for when you lose remote control of the remote computer. This can happen due to various reasons, including TeamViewer failing or their server encountering connectivity problems. It is sometimes necessary to restart the computer, or TeamViewer alone, for example, in order to recover remote control. When all else fails, parking your mount and closing your roof may become necessary measures to protect the equipment against possible collisions and from the elements. It is here that Tweet Remote Control can assist, provided the remote computer has an active Internet connection, of course. This stops you needing to have someone to immediately attend to the equipment physically. Put simply, Tweet Remote Control starts with Windows and runs in the background. It connects to a Twitter account of choice and therefore responds to specific commands, effectively sent by tweeting them via the connected Twitter account. The program monitors this connected Twitter account and reads new tweets made. If a tweet made matches a command written into the program, it deletes the tweet, executes the command received and tweets on your behalf (to update you on what is happening). Since all the program requires to function is a connection to a Twitter account, it need only be running on the remote computer with an active Internet connection - the rest is up to your tweet commands! Many features are supported, including control of ASCOM roofs, mounts and power relay switches (as well as Lunatico Astronomia's Seletek Dragonfly). Tweet Remote Control ensures it always starts automatically with Windows (once you connect a Twitter account, that is), and re-authenticates with Twitter automatically every two minutes. This ensures the program is always active with minimum delay, even if the remote computer's Internet connection drops for a period of time. When Tweet Remote Control starts, if it is connected to a Twitter account, it does so minimised to your Windows system tray as a small, black and white icon labelled TRC. Here, the program will remain with no user input required and with no pop-ups whatsoever. The key is being always-on and always-ready without user input and without hassling the user with pop-ups or messages. Finally, Tweet Remote Control is 100% free. Please feel free to contact me for bug reports or to request new features be added! Current list of capabilities in version 1.4: 1. Restart your computer 2. Shut down your computer 3. Restart TeamViewer on your computer 4. Close an ASCOM roof 5. Open an ASCOM roof 6. Check the current status on an ASCOM roof 7. Park an ASCOM mount 8. Check the current status on an ASCOM mount 9. Open power relays (turn off) on a Dragonfly 10. Close power relays (turn on) on a Dragonfly 11. Check power relays on a Dragonfly 12. Open power relays (turn off) on an ASCOM power relay switch 13. Close power relays (turn on) on an ASCOM power relay switch 14. Check power relays on an ASCOM power relay switch
  17. Hi All, So we were down at my parent's at the weekend and I've been working on my ongoing project to refurbish my old telescope so my Dad can use it - a Tal M from 1994 (!). Here's a picture of this vintage 'scope: As you can see everything is fine except for the fact that one of the tube rings has shattered in a fall. I need to replace the second tube ring but have no idea how to go about it. The rings are cast iron, and here is a picture of the broken ring for reference: What I want to do is either: Mend the broken tube ring Replace the broken tube ring Find some other way of attaching the telescope to the mount. It's an 88mm / 3.5'' reflector. Really nice 'scope - we gave it a whirl to check the optics and got it pointed at Saturn and it still shows a lovely clear picture. My Dad was careful to keep the tube somewhere the dust wouldn't get to it. Which of the above options would be the best solution to fixing this fine telescope for my old Dad?! DD
  18. Hi, I have Bresser EXOS II EQ5 mount with dual motor drive. Want to upgrade to GOTO + guiding support. Read many negative reviews about GOTO Upgrade kit given by Bresser. So wanted to know are there really such issues like incorrect GOTO, loud noise while slewing etc. If yes, then as an alternative can we use Sky-watcher Synscan GOTO upgrade kit with Bresser EXOS II EQ5 mount? Will it work? Thanks! - Abhijit Juvekar
  19. I propose a group purchase of Rocol Kilopoise from RS. It's £65 or so for a tub of 500gm and I can't imagine needing more than 50gm in a lifetime. Various discussions here regarding mount regreasing have identified this grease as the lubricant for worm gears (not bearings) having high shear and high viscosity properties. Anyone interested ? Mike
  20. In another topic I saw a link to (and watched) a video which, to be honest, seemed more like an advertisement than an objective assessment of the construction of piers. One of the topics to consider was the resonance of the pier, or how much vibration was likely to be imparted to the scope should something hit the pier. This set me thinking. In years gone by I dabbled in a bit of railway modelling and one of the books in my collection is "An Approack to Building Finescale Track" by Iain Rice. Now, you might be wondering what this has to do with piers etc. Well, in the book, Iain tackles the problems of baseboard noise. His solution is to use techniques in the audio industry. If my memory serves me well, this involves "Acoustic decoupling" involving materials of different densities so, for example, you would have the timber baseframe, an MDF sub-frame, a layer of fairly dense foam (such as used in camping mats/garden kneelers) then another MDF subframe. The foam would absorb much of the vibrations caused by model stock trundling along. Now, I'm not necessarily suggesting pier tops are made of foam, as that would be pretty daft. However, I was wondering if some form of dense foam could be used between mount and top of pier. The key thing, I think, is the use of a material of different density which can absorb vibrations caused by something striking the pier, perhaps introducing foam/neoprene "washers" on the bolts attaching head to pier so that there isn't a metal on metal link through which vibrations could travel. Useful idea, or am I talking out the top of my head?
  21. 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?
  22. I really needs help asap guys please. I had small play in my RA worm gear so tweaked it and now no play. Problem now is the RA turns as normal, but has no torque as in, I can put 1 finger on the weight bar and it stops, makes a grinding noise. looking at the motors with the side panel off and it's not gears slipping, it's the motor itself won't rotate. What could the problem be? I was looking at buying a skywatcher Quattro tomorrow as well. Please help!
  23. Hi In my quest to identify a mount, I would like advice on the Losmandy G8 - the basic unit without add ones is $1500 +tax and shipping, and this is somewhat beyond my budget. However, the reviews I have read seem to suggest that it is a far superior mount than the usual Celestron, Orion, Sirius, atlas etc. Is that true that Losmandy G8 is a better mount. I will be using the mount for AP (upto three minutes), is it a feasible with a basic G8 unit without the Gemini unit. Telescope is 5" MAK (8 lb) thanks Rajeev
  24. Hi all I'm looking to build a 10" budget equatorial telescope. I know it sounds like a contradiction in terms, but I've almost managed it. All I need now is the tripod part of the mount as I have the actual equatorial mount minus the tripod. I also know a CG5/EQ5 is a bit small for a 10", but I have my ways to lighten it up. Thank you. PS. I'm also looking for counterwight bar, counterweights (13kg telescope, but will reduce to improve tracking), motor drive(s), and polar scope. Ta.
  25. Hi all, I'm looking at buying a Skyliner 200p scope second-hand, but it doesn't included a mount or eyepieces. Is it possible to: - Pair this scope with reasonably a priced mount (<£100) or even a tripod used for birdwatching (do you need a specific mount for this scope?) - Get an OK set of eyepieces (<£50) used for seeing planets and some beginner DSO. - Advise me on a telescope mount and eyepieces compatible with the Skyliner 200p for the prices stated above. The reason i'm asking is because my funds are limited ATM, so i'd like to buy a decent telescope with the intention of upgrading its accessories as funds permit and my astronomical knowledge advances. Any advice would be greatly appreciated.
