Yes! Bad telescope! ((( 500 eur in ass....

See astroshop managers answers:

Thanks for your reply !

Honestly, we have to stay clear. You're expecting to much from this telescope ! That's why my colleague suggested a 7mm eyepiece, maybe just an 8mm one. No need to talk about quality reducing while the use of an barlow element. Just a relatively small portion of quality loss, maybe one percent or less. 

Hellou! So i bought that:
my telescope with original 10mm and 25 mm: https://www.astroshop.eu/telescopes/skywatcher-telescope-n-130-650-explorer-130ps-az-5/p,55150

and svbony set 6-9-15-20mm 68 degree UWA from aliexpress (i hope don't get forum block because of link): https://www.aliexpress.com/item/32840105236.html

So, i have on this time 2 nights, and see only Jupiter with 3 satellites and orange Saturn with ring! With 10mm ok, with 9mm a little bigger - ok, with 6mm bigger - but picture not clear with 6mm!

1. Why no clear picture with 6mm? What i can do to make clear? Maybe because i don't use your recommended 6mm one https://www.astroshop.eu/eyepieces/levenhuk-eyepiece-ra-ler-6mm-1-25-/p,78246  ?
Another your college from astrashop tell me such:
"The Svbony eyepieces are good. For this telescopes, a 6mm eyepiece is too much maginification.
You could try with a 7mm: https://www.astroshop.eu/eyepieces/omegon-eyepiece-cronus-wa-7-mm-1-25-/p,32983  "

2. On other e-mail he said: "Quality will reduce with a barlow!"
So what to do? I need a barlow? What about quality reducing? Barlow i need to use only with 20mm and 25mm oculars?

I don't know what is my type. Please give example with such parabolic telescopes.

1. I ask astroshop managers, they tell that with 6mm not clear because it neat range of my telescope, and reccomend bye 7mm.

2. And they sell that Barlow will loss quality in output.

3. What barlow recommended?, because I afraid if pay 50eur or 100eur I will not get good...

Yes - city night! ((

And saturn low in horizont, in north sky it will always low as I understand!

What about Barlow? I need it?

so bad?

1. Why no clear picture with 6mm? What i can do to make clear?

2. So, maybe i need some accessories else? Another eyepieces? Barlow? Please link to barlow what not so expensive! I'm not millionaire!

3. You all see sky through camera? or through eyepieces too?

4. Or my telescope so bad and better nothing do with that? )

At start i want see some objects with physical eye - in another topics i will start about astrocameras and other beginner questions )).

Having read your post a few times, I suspect your issue is similar to what I experience, I cannot keep my non viewing eye closed for very long and the view from my viewing eye gets impacted. Try keeping both eyes open and cover your non viewing eye with your hand, this makes it slightly more comfortable than closing one eye all the time. Some people use an eye patch to do this rather than using their hand.

i need to keep not-used eye OPEN?

if i will use patch (because difficult use hand all time) - with patch possible to keep eye OPEN, or eye goes CLOSED because of patch?

and svbony from alexpress (i hope don't get forum block because of link): https://www.aliexpress.com/item/32840105236.html

ups - they realy 68 degrees... sorry (when i bought i much think about 82... )

As a general rule, the higher the power of the eyepiece (lower the number), the eye relief of the eyepiece becomes less and less, so your eye needs to be closer to the eyepiece when using high power eyepieces. You cannot keep your eyes far away from the eyepiece if it is not a long eye relief eyepiece.

With wide angle eyepieces to get the whole FOV, your eye needs to be fairly close, or close to touching the eyepiece via the eyecup, you won't get the whole FOV any other way, especially if it's an 82 degree one.

yes! i one moment i found that that black appears much later when i hold closed other eye with hand !

realy help me! i ask astroshop managers that question - they answer that don't know and maybe oculars bad quality! So with yours help will try again and will turn eye away!

ok! thanks for all! i get answer! 

I was start thinking about getting Svbony oculars back to Aliexpress! ))

Your eye can take in about 65 degrees so with the extra wide angle eyepieces you need to look around to see the whole vista but if you move too much you get blackouts. When I first looked through 83 degree eyepieces I hated them but I learnt how to look through them and now I love them.

ha-ha-ha - i hate them too ! ))))))

1. with original (not written angle) - Wild Angle only - so they for example 60 degrees or smaller and with them i see all "picture" and don't try look around! Here all i understand!

2. can explain how, if i will try stay away 1 cm with eye from ocular, how to look around with eye? )

Try holding your eye further away from the eyepiece and try to keep it central.

and why with original 10mm and 25 mm wild angle oculars not such problem?

i try answer myself: because in that wild angle i see all "picture" with eye and don't trying to turn it around?

how cm away i need hold my eye?

hmmm - i think that rubber top in eyepieces needed to hold eyebrow exactly on ocular...  Away from ocular - i will need to focused focuser again?

You have to hold your eye in exactly the right place to see through these super-wide field eyepieces.

i try my eye turn around! don't help me!

How i need to see in ocular? i just in astronomy 2 nights! ))

Telescope N 130/650 Explorer-130PS AZ-5! In complect original eyepieces 10mm and 25mm! I bought svbony 82 degrees 6-9-15-20 oculars! So such problem: "I don't know what's wrong with those SVBONNY eyepieces! I look with one eye in svbony eyepiece! Suddenly it feels like I blinked with other eye (that don't see in eyepiece, it realy stay black not like turn off, but slowly closed like eyebrow close eye) and all in ocular stay suddenly black (like my another eye don't let me see with eye what see in eyepiece)! And everything stays black (in that black moment i try watching inside eyepiece around) until I take my eye off the ocular! I don't understand that moment when it stay black! Look-look for example minute, and suddenly someone say "your eye tired and need sleep". With original 10mm and 25mm eyepieces not such problem!”
