Hi all, looking for some help please! 🙏 I have a wedge for my 8SE and when using EQ North to align it, it says it is slewing to Vega but ends up all the way over at Polaris!?  Any ideas? 🤞🏻 Thanks in advance! 😊

 

I have updated the firmware, Mount is pointing at north, have inputted my latitude and longitude, I have tried picking the nearest city too and nothing seems to work! 😟

hum I have never used my nextar 8 or nextar8se with wedge...

have u just tried to to slew to vega push alaign? then do 2nd star see if it gets successful and put objects in the ep. that's what really matters

also do u know most gotos when slewing to alignment stars can be off by 5 degree up to 15 or 20 degree?

Does it work properly in alt-az mode (without the wedge)? If it does not, you need to sort that first.

What exactly are you trying to accomplish? I am guessing you have astrophotography in mind, as you certainly do not need the wedge for visual. I have this scope and mount and have found that while the SE is fine as a portable visual mount, it is a pain to use for planetary astrophotography, and as for deep space long exposure astrophotography I think it's about as much use as a three-legged dog (and I don't think a wedge will make it any more suitable).

If you want to do ANY kind of astrophotography with the C8 I strongly recommend you get the right kind of mount for the job - for planetary astrophotography a solid and well-behaved alt-azimuth GoTo, or driven or GoTo equatorial.   For deep-space astrophotography you'd want a solid equatorial mount, but a small refractor and a big equatorial GoTo mount like the HEQ5 or EQ6 would be a better setup.

Maybe you have the wrong GPS coordinates in the hand control. I use wedge and follow these procedures.

1) Turn on the telescope
2) Press "ENTER" to get started
3) Select EQ-North
4) Select "two star autoalign"
5) Press BACK to change GPS coordinates
6) Enter coordinates, clock, date  ENTER between each.
7) When asked if you have "daylight saving", select the default time

😎 The hand control asks you to drive to the index mark (on the arm of the telescope)  ENTER

9) The hand control asks you to drive to the meredian (Sideways until it points north)  ENTER
10) The controller selects a star  ENTER and the telescope runs to it
11) Fine tune ENTER fine tune ALIGN
12) The controller selects another star  ENTER and the telescope runs to it
13) Fine tune ENTER fine tune ALIGN

Wrong procedure is the culprit. I also suspect that KS's procedure is for an older or different model. Below is correct for a recent SE model.

The original 'wedge align' instructions in older SE manuals are wrong! Today, the NEW routine is known as an All Star Polar Alignment (ASPA).

Do this if using Nexstar + HC or Starsense HC.....

1. Set OTA at its index marks.

2. Set wedge to your latitude.

3. Move tripod to aim OTA South (if in the Northern Hemisphere). Next time do this first, but it is easier to describe this way around!

This is where your error is occuring.  You should be aiming OTA at its Index Marks at the SOUTH Celestial Equator and not North/Polaris. This fools everybody that has an older instruction manual or look it up on line.  Your mount arm is now leaning North.

If using Starsense HC via <menu> set wedge = yes. To be honest, I can't remember if this step is necessary in the Nexstar + HC. I think not. But I know the rest is correct!

4. Do an EQNorth Align with Nexstar + HC (or Starsense autoalign)

5. Do an All Star Polar Align. All instructions are in HC scrolling window.

This will entail turning wedge knobs to eliminate the Polar Alignment Error (PAE)

6. Repeat EQNorth Align (or Starsense auto-align).

7. You might need to repeat to further converge PAE.

Note that if using CPWI the procedure does differ, follow on screen instructions.

Note also that it is vital your HC and mount firmware is later than December 2018 when the ASPA routine was rewritten from the bottom up. Even if your scope was delivered after that date, it is quite common that firmware might be out of date.

I agree with Noah4x4 which is the latest method and it works fine for me and my Nexstar 6SE. when taking long exposure imaging with my DSLR, typically around 90seconds for closer Deep sky nebula, I normally repeat the process a couple of times to fine tune. I totally disagree with Cosmic Geoff who claims the alt/az setup is unsuitable as I have had very acceptable results without spending £ thousands on top end EQ mounts. my mature advice is to spend time on the set up.. Accurately level mount before carefully going through alignment. My first attempt at deep sky on my new wedge was the Whirlpool galaxy, image attached.

cheers

      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
