@Ricochet Hey, there are two versions of the telescope (90/900 one) there is the AZ mount for 200 and the EQ mount for 230, is it worth getting the EQ mount for 30 Eur more?

https://teleskopy.pl/product_info.php?cPath=21_33&products_id=1424&lunety=Teleskop Sky Watcher Synta R 90 900 AZ 3

https://teleskopy.pl/product_info.php?cPath=21_33&products_id=1304&lunety=Teleskop Sky Watcher Synta R 90 900 EQ 2

I had both of these mounts.

EQ2 was not very stable with larger 130mm F/7.9 Newtonian but it was usable. It is EQ type mount so you'll have to learn polar alignment to use it properly (not hard thing to do - you need to point it to Polaris / North pole - for visual it needs to be approximate).

It is a bit more awkward to use than AltAz mount in the way scope moves - but once you understand how it moves - you won't have problems pointing it and using it.

AZ3 is more stable, but it has a few issues that really annoyed me. I don't think it is suitable for long scopes.

- slow motion controls need to be "rewinded" after you use them - they are not continuous and have certain amount of back and forth. If you track the sky - you'll reach the limit and will need to unwind them in the opposite direction to be able to track

- mount has issues when observing near zenith - best place to observe since there is least atmosphere and light pollution there. Scope is nearly impossible to point straight up and longer the scope - more problems you'll have.

Out of the two - I'd go with EQ2 version although I prefer AltAz for simple observation.

I've received my 130p first time looking trough a telescope, it was so AMAZING, there were way more stars than I thought I would be able to ever see in a city. Thanks everyone for helping me pick out

You may well have seen this recommended elsewhere, but if not, you could also take a look at this list of objects that are visible from light-polluted skies: https://las-astro.org.uk/docs/Loughto

So after all, I'm answering kinda late, but I found a 150p for 260 from Finland, so I ordered it, for people who are interested I'll post a follow up once I recieve it, about my expirience, thanks for

If I went for the reflector, what do I need for collimating?

For the mount I am thinking of maybe buying a small wooden portable table or something like that, so that shouldn't be a problem.

I don't use anything for collimation of my dob - just a star.

Secondary stays in place very well and with open tube design it is very easy to align it properly. Primary you can adjust just by looking at the out of focus star pattern.



These images show how can you tell if telescope is out of collimation. Just make sure star is in the center of the field of view (best to use Polaris as it will not move) and use high power eyepiece. Do slight defocus and if rings are not concentric - you need to fix the collimation.

As soon as you move primary mirror - you'll see the change in star pattern - move so that you make circles concentric.

I use a heritage 130p with it on the floor and I sit on a garden chair. Sometimes I raise it up by placing the whole lot on an upturned bucket.

A Dobsonian and a copy of Turn Left at Orion is a great choice.

I wouldn't get hung up or start panicking about collimation. You can order a collimation cap when you get your telescope. I made one from a lens cap and a shiny washer.

When you are ready, check out these...

hopefully it's not too expensive 

I paid £23 but it is worth it IMHO. Someone did find a used one on FB marketplace for a tenner, so you might get lucky 🙂

heritage 150p came with a collimation cap included, so a 130p might do too

It does seem strange that the 200P classic does not come with one 😞

The 150P is a great scope imo and often overlooked. Much more light gathering than a 130 whilst staying a very sensible size, unlike the 200 which is starting to get a bit cumbersome - especially to beginners. 

I've got many of my astronomy firsts with my 150P, it's never going to be sold :)

That's very exciting! You should be able to observe loads of stuff with that, but remember that what you see (and whether you can see it at all) will depend on multiple factors including light pollution, phase of the moon, how high the object is in the sky etc). I dont say this to discourage you, but to encourage you to pick your targets depending on where you are and how the conditions are on a given night - as recommended before, Turn Left at Orion is very helpful in making the choices of what to look at.

Best of luck, I look forward to hearing how you get on!

Thanks, I'm currently looking for a book guide for sky, I wanted to buy left at orion, but it isn't in my local stores, might have to buy from amazon. Thanks for advice, I'm really excited!

Most diagonals and Barlows come with dust caps at each end, and most OTAs also have a dust cap at the focuser. I turned one of these into a collimation cap by drilling a 1mm hole in its centre.

Hey, I wanted to know should I order a 2x or 3x barlow lens? I noticed that the 150p doesn't come with one and I've heard they're a big deal, if I should, can someone recommend me some decent cheap ones? Or is it better to stay without for now?

The advantage of a Barlow lens is that when used with an eyepiece it gives you the magnification twice or three times the 'power' with the same size eye lens (some eyepiece designs result in smaller and smaller eye lenses as the focal length decreases).

The downside is that the optics aren't necessarily optimised when a lens is used with one. Generally, the image will be okay, but it would usually be possible to get a better image with a decent equivalent eyepiece.

Another is that there is a temptation to use it to give too much magnification. 

I have a 2x Barlow that I use with my 32, 24 and 18mm eyepieces, so that I effectively have the use of 16, 12 and 9mm EPs as well.

I wouldn't use it with my 10mm eyepiece, as it would be too much for my f/12 scope.

There's a nice Celestron combined Barlow/t adapter that could be worth getting as you can also use it to attach a dSLR to your scope.

I've just looked back up the thread and seen that you're getting a Newtonian scope. So when I mentioned 'attaching a dSLR to your scope', a Barlow is very likely to be needed to be able to get it to focus. 

There are Newtonians that can be used with a SLR camera, but they need to be specially designed for it.

      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!

      Hi I've got an 8" dobsonian and I just got a dslr to connect to it. Obviously there's no tracking so what kind of things can I capture. Will I be able to do dso and planets?

      Good day fellow gazers at the sky! I recently joined and i would just like to say how wonderful everyone is (a special shout out to George Gearless)!
       Can anyone suggest a good reflector within my budget shown in the title? While i'm here i'd just like to say about the app, Nightshift. It is proffesional, clear and tellls you when to observe, and what you can see, for the next year! It also pinpoints your location exactly, so it is really accurate.https://play.google.com/store/apps/details?id=com.waddensky.nightshift. Anyway, that's me done! Thank you all so much for your time

      Hello all, 
      I have come to you all with the "too much asked question". 
      I have been using the telescopes from local Astronomy group since few years, and now during these Corona times, it is harder. So now I have decided to invest some money on getting myself a scope, and would so sooooo would love your inputs. My main concerns are:
      I may use it only once a month or so, I wanted something that I can handle (maybe >10kg). 
      I don't own a car, usually I use a bicycle with a carrier to get around the city.
      (I had a look at the second-hand (5-7 yrs old) Skywatch MAK 127 Cassegrain that my friend was selling with its mount and accessories. I felt it was too massive for me. Especially if I am getting it to a park and setting it up alone).
        I would like to have a look at celestial objects and also at deep space. 
      As far as I know for deep space, I would need a f5 or something with similar focal ratio, and for planetary object a higher focal length (f10 or more) is better.
      I looked into MAK 90-1250, but felt like it might have very narrow FOV. So I am lost here.
        My budget is small (I know that is the biggest problem). I can spare maybe 200€ to 250€. I know its not enough, so I am hoping to start with a decent one (not awesome) and then work my way up. I so need your advice on what might be good parameters to look for
      - I was thinking Newtonian around f8 or so
      - Since its my first scope, maybe get something small and something that I can get comfortable with and use with a bit of ease before getting expensive ones.
      - Also definitely not a Dobsonian mount, I need something that I can set up on lawn or pavement. 
      Is this a good one to start with? Look at planets and maybe some deep sky ones
      I also has my eye on this, but I cant find much reviews  Any other options are quite welcome.
      I tried to setup and use the telescope in the picture, it was quite hard to do it alone and move it around.
      Thanks a lot. Sorry for the saga...

      Hey everyone !
      Hope your all doing as well as you can be with this pandemic ! Im completely new to this stuff, im looking for some advice on the right telescope kit to buy. I dont want to be spending too much cause like im new and wanting to try it out, just hoping you guys have got some suggestions for telescopes for the value.
      Mainly wanting to look at stars (my stepdad passed away 3 weeks ago and my partner bought a "name a star" for him and would love to see it properly) and im interested in see the planets like the rings and stuff too
      Any help would be very appreciated ! 
      Possibly below £100 the cheaper the better at the minute but dont want it to be so cheap and tacky that i can only see the end of the garden through it lol
      Stay safe everyonr
