Hi.

i haven just purchased my first telescope (Celestron Nexstar 8SE) and I'm trying to source the correct AC adapter for use in the UK. Does any know which is the correct one - 3 pin version and where I can get one. 

Many thanks

Did you not get an AC adapter with the scope?. You want a 12v adapter. To run the scope you really need a power pack (battery). If you are near a mains.....then the AC adapter will do.

Power packs (leisure batteries) can be bought cheaply enough from the likes of Halfords. Much cheaper and last longer (17Ah) then branded ones which typically last about 7 Ah per session.

Maybe i'm confused about getting an AC adapter with my 8Se. I know you can run them off of AA batteries (they are expensive and will not last very long). A battery pack is much better. Its 12V anyway that you need.

If indeed you want to run the scope off of mains supply then something like this will do:

Of course this is Baader branded, so quite pricey. A non#branded run of the mill similar adapter will do the job.

Thanks Paul

i know you can use AA batteries and a 12v battery pack but I'm looking for a mains adapter for when I'm at home. I know they have one in the states. 

Nick

The States and the UK run off of different currents mains. Do you mean a 3 pin plug (UK style) as against a 2 pin plug (U.S. style)?. Would a simple travel plug adapter not do the job?.

Where is "at home"?. Are you in the UK most of the time or do you perhaps live most of the time in USA?. 

I'm a tad confused.

A 3pin  240v mains PSU delivering minimum 2amps 12v dc with a centre pin positive jack plug to suit the 12v input unit on the 8SE mount should be all you need. 3 pin to 2pin adapter for continental use are easy to source.  :icon_biggrin:

Hi Nick,

I bought one of these recently and it works with my 8SE, HEQ5 and NEQ6. Their price is £27.99 with free P&P. Hopefully, this will do the trick for you unless you can find one cheaper although I'm wary of buying "cheap" electrical products for obvious reasons.

http://www.modernastronomy.com/shop/accessories/power-supplies/100240v-ac-input-12v-dc-5a-output-psu-with-right-angle-plug/

When I am at home I plug it into an outdoor grade orange extension cable which has RCD protection. These are more expensive to buy than standard extension leads, but a life is worth more than the £20 or so you'd pay for a decent outdoor cable.

Anyway, I hope this helps and good luck :)

Hi Nick, just in case it wasn't clear, this product does not come with an alternative cigarette lighter type end for use with a powertank or such like. It just has the UK power plug. If you want to use the 8SE with a powertank you'll need a different power lead, although reading your original post it seems that you'll probably just be using mains power at home. Pleased I could help you. Just make sure you use the correct outdoor RCD protected extension cables when going outside with your scope. I've heard stories about people being blown across their gardens whilst using indoor grade extension leads. Not good. Safety first :)

Clear skies!

Hi Nick,

See photo of the power adapter I bought, and also my outdoor grade extension cable. 

I have also taken a picture of the pin plug to cigarette plug adapter you'll need if using a power tank. I got this with my 8SE and although I did buy my scope second hand I presume it originally came with ths scope and you should be able to pick one up if you ever need to. 

However, if I am using my scopes and mounts away from home I do tend to run them off an inverter from my car as I find my powertank (which is the Celestron 7ah version) will only do a maximum of a couple of hours.

By the way, don't even try AA batteries. I did that the first time and they didn't last long. Waste of money.

Hope you get sorted.

Vicky

I bought a couple of of these from US for about $17 , about a year ago: 

NotAvailable55.jpg
Shipped
1
$16.95

Still available but more expensive: https://www.ebay.com/itm/192273903687

I think there's a new version now https://www.celestron.com/products/ac-adapter-2-amp

I prefer the previous version for the longer cable (I replaced the US lead with 10m UK lead)

      Hello,
      I've been on these forums a couple of times for the last 2 weeks and ive found amazing advice, on telescopes, mounts and eyepiece. Besides reading countless of information on the internet about various equipments; pros and cons; and i got some queries about how to upgrade my setup.
      My original purchase was a 15x70 Celestron Binoculars last year, and boy ive seen amazing things with it, specially globular clusters, Jupiter and Saturn and the Orion's Nebula; for me these were amazing; i still use them given how easy it is to look at the sky with them and how bright and full everything looks.  A couple of months ago i got a 70x400mm Gskyer Telescope with an AZ mount (The cheap 99$ one that Amazon is displaying on all its adds for the last two months)  it came with a 25mm and a 10mm eyepieces as well as a x3 barlows (which i didnt even count as part of my scope as it is too bad quality and i havent managed a single decent view with it).

      Currently My Celestron Binoculars (x15) seem better for visualizing the sky than the 25mm eyepiece (x16) (things seem a very bit dimmer). And since the Barlow is a "no go", the 10mm (x40) eyepiece is what i really use, it has decent zoom and detailed views , it is my go to eyepiece most of the nights.
      However from reading all around, ive read that most of the stuff that come with the Telescope (aside from the scope itself) are actually really bad quality, specially no name brands without even webpage, so if i were to maximise my telescope i should update some of those items.
      -Recently i ordered a new Start diagonal to replace to default one (ive heard on Refractors its usually the weakest link next to eyepieces) as well as an economic x2 Barlow lens
      Keep in mind i recognize my 70mm cheap telescope will not suddendly become the Hubble Telescope, and that it doesnt matter how hard i push it, in the end such a low scope will be bound to hit its limit pretty fast, thats why i avoid 70$+ eyepieces and barlows for now.
      I expect to keep using this telescope for a good couple of months; at least until around August, when Jupiter and Saturn are more in the night sky, rather than morning.

      Now, im very satisfied with my current telescope; while the phone mount is garbage and the phone weight and the sound of my heartbeats pretty much shake the telescope out of position, as well as how cheap the mount is; it still gets the job done for seeing interesting stuff in the sky and i have managed to do some AP for some of the globular clusters, bunch of 1-2s images (with the wrong lens), not the best, not even good pictures; but decent overall for my equipment. I am currently interested in stargazing in general and some minor AP (as i dont have a camera, currently an Iphone 7s with the mount) Buuut im interested in borrowing a camera for the low sky photos without a telescope.
      I do most 97% of my Skywatching on my backyard, i live in a small country, there is some light pollution, but i can see the pleiades and the orion's nebula core on the naked eye most nights (so i guess its not that contaminated lol)
      Now; currently i like finding stuff by myself and show it to the other people around me who cant be bothered to find the moon in the sky, so setting up, finding and seeing stuff is part of what i like. 
      With all the above in mind..... Id like to plan ahead for my next purchases.
      First, im thinking a x3 barlow lens (to replace the original crappy one) and a 15mm lens (to have a bit better view than the 10mm, but less spread than the 25mm) in two or three months (with this id be able to check if my new eyepiece outperforms my default ones, but given the quality of the scope, i dont expect this to be noticeable).
      And Afterwards id love to get a new Scope, but im not quite sure what i want... and i would like some advice and help in choosing my next Scope upgrade.
      -I entered with and im liking the refractors; however i dont wanna spend 300-400$ on another refractor that is 20-30% better for triple the price
      -Ive heard really long focal lenght might bring some distortions; and also make the scope much bulkier, annnd most importantly i know that magnification is not everything; so a 1000mm long tube would prob bring too much magnifications for me to use properly on my backyard skies. So i think id settle for a maximum of 600-700mm.
      -Originally i was againts Newtonians in general, those inverted views scared me, i have a hard time of my own with my finderscope. Then i found out that Reflectors are the name of efficiency as they have more value per aperture than refractors; and as someone once mentioned "There is not really up and down in space, you will get used to it" annnd its true... save for references on the ground, like buildings, trees and mountains to help you locate where you are in the sky; once you are on it, you dont need right ups and downs.
      -I did see some 90mm Orion's Refractors as well as 90-102 Celestron Astromaster Refractors (these are 350-400$)
      -Im thinking a 130mm reflector is what im looking for; i think the 130mm aperture is a nice upgrade for my 70mm, and will keep me occupied for quite a long time; ive read about Orion SpaceProbe 130EQ and Celestron Astromaster 130EQ (ive also read, Power Seekers and Astromaster's are made out of pretty much garbage lol) Ive read that the main issue is the constant collimation required for them; but ive also read its something that can be learned and once you get used to it; its a pretty easy thing to do to keep getting amazing views.
      -Ive also seen people recommending  6-8'' Dobsonians; i know the deal with them; if anything i could aim for a 6'' one i found a litter under 300$ ive read they are amazing values for their aperture
      So, TL;DR: I have a 70x400mm Telescope, im new to stargazing, im really amazed and excited by what im seeing with my current scope, but would like an stable upgrade before the end of the year that will last me a year or two. I am interesteted both in regular and deep sky stargazing and astrophotography;  im not currently interested in an motorized mount; could deal with a regular Equatorial mount. But overall i am looking for  more aperture (100-150mm) to have clearer views; than focal lenght for zoom.

      Im also open to the fact that at one point i might have to get a scope for stargazing and another for AP; but would like an upgrade that could help me all around for both while i get initiated.
      ------------------------------------------------------------------
      Sorrry for the Huuuuuuuuge post, i was very excited while writing it; please let me know what you think and if there's anything else you'd want me to add to help understand my situation, thanks in advance!

      This is Celestron cg3 mount suitable for any telescope tube with vixen dovetail.
      Load capacity is approximately up to 4 kg
      Condition is used, but in very good shape. 
      It's comcompletely with 3d printed levelling plate, under tray for accessories, slow motion and locking knobs.
      Mount was completely stripped down, removed factory sticky grease and applied proper grease where applicable.
      Price: £90
      I can post it by Hermes or DPD if you are happy to pay for postage.
      I'll accept PayPal as family/friends or commercial if you'll pay the 3% fee.

      Complete newb here only 1 month in to it all.  Researching as much as I can each day and trying to learn new things every hour.  Here's my rig:
      Celestron AVX 8" SCT
      Celestron AVX Mount
      Celestron 2x Barlow
      Various Celestron additional eyepieces
      Celestron Starsense Auto Aligner
      ZWO ASI 224mc color cam
      I believe I can use the 224 cam as part of an auto guider solution and am wondering what else I would need for that, assuming I would be best servers with an off axis guider solution.
      Many thanks in advance...

      Good evening everyone
      I am looking at a SkyProdigy 6 telescope for a friend. the mount had a rattle/lose part. I partially unscrewed the casing and the plastic cylinder pictured below fell out. Anyone got any idea what it is or where is comes from. Looks plastic but can feel metal in the centre.
      Does anyone have a service manual or disassembly guide?
      Many thanks in advance
      Steve

      I'm after a cassegrain reflector but I don't know which one to buy,
      I have a celestron c5 and it worked wonders for all fields, I now want the same but twice as powerful as my final upgrade
      I am looking at a c9.5 for £1350 or a c11 for £2000, My question is an extra 2.75" focal worth it for £750 more?
      I will likely purchase one this week
