Have you seen the Bresser 70°-Series 6-piece Eyepiece Set for 250 bucks? I am after a 35mm EP, and the set has 2" 25, 30 and 35mm for less than any  decent 35mm I have seen...what gives,? are they poor eyepieces? The 15mm would also fill a gap that I was planning to purchase a 14 mm for. Seems to good to be true, like when I found out about the 3-6mm nagler zoom with its yellowing effect,small field and not recommended for focal lengths over 900mm. The set has my interest.

70 deg EPs in this price bracket tend to be prone to lots of astigmatism in the outer part of the FOV in faster scopes. They look like the GSO SuperView EPs in a different branding.

I see. Would you consider an f/7.5 to be a faster scope?  Seems to be kinda in the middle to call it fast, or slow.  F/10 is slow to me and roughly f/5 fast?

The EPs may still be OK at F/7.5, can't be sure. I know that Hyperions start to fall apart below F/7. I do not think these will be better. If you are after a 35mm or so, I am pretty sure the MaxVision 34mm 68 deg will be much better. The 24mm I have is excellent in my F/6 refractor, holding its own against a Nagler 22mm T4. In an F/4 scope they start to show issues. It is still available for a very reasonable price

The Explore Scientific of the same specs has the same optics, I gather

Agree with Michael here. The Explore Scientific versions are identical optically, but better build, and waterproof/dust proof. Also I prefer the Tele Vue type eyecup.

The Maxvisions are good too though, check out Bresser.de/sale and see what us on offer..3/decent EPs vs 5 so so ones makes more sense IMO.

      Hi there people, 
      Firstly can I say what a joy it has been reading and learning from some great posts by your community. 
      My question (as a complete newbie) has probably been asked and answered many times before but some posts are quite old so I hope that you don't mind me re-asking in case there are more upto date answers.
      Ok, I am looking at purchasing the SkyWatcher heritage 130p as I want a portable telescope to take to South Africa with me and after reading the forums it seems like a good option. I will be there for a few months including being next to the Kruger National Park where light pollution will be at an absolute minimum so I am hoping for good results . 
      I have read that a 150mm would obviously be preferable but is there one that is portable  ?? I carry very little luggage so I can accommodate a reasonable size perhaps upto around 10 kilos or so if such a scope exists and would fit into a case that can go into cargo or would this be a no-no ?
      If there are any options please can someone advise. 
      If I do end up with the 130p then I will have a budget of upto £150 to get any additional equipment (ie :- eyepieces) that may be required or would I be better of spending £300(approx) on a different scope with little to no budget for extras ? My intention initially and perhaps ultimately with a travel-scope would be observing the planets only and would obviously like as much planetary detail as feasibly possible but I certainly don't expect Hubble like images !
      I have intentions of purchasing a larger scope at a later date for home use so it really is just about a portable telescope at this stage. 
      Can I say many thanks already in anticipation of some quality feedback from you lovely people !!

      Hi, i..m on Stargazers Lounge for long time ago, but now i have a new scope at last!!! The scope is a Skywatcher classic200p dobsonian, and i received it just one month ago. I.m really happy with it. For now, i.m using the stock eyepieces that come with the scope, a 25mm and 10mm super plossl 52. Yesterday i was received a Celestron Omni barlow, and that expands my magnification range. I posted some pics with my set. 
      Congratulations to Stargazers lounge team, this is one of the best sites to learn about astronomy and equipment. 
      Besf regards to everybody

      So, i have settled between 2 eyepieces for my scopes.
      The explore scientific 6,5 mm 52degree 
       
      and the Skywatcher UWA Planetary 6mm
       
      I have read that the explore scientific gives better contrast and views.
      The explore scientific will give me 184x and barlowed 369x So should i trade less magnification for more detail?

      Dilemna time......
      I've realised that I'm not a fan of barlows, I'm also not loaded with cash. I love my two BST's 8mm and 25mm, I'm not so keen on my 15mm meade.
      I've recently expanded my scope collection due to some inheritance with a 127 Mak, so my question is what would be a benefit to my eyepieces, replace the 15mm with a BST? Go lower than my 8mm? Go higher than 25mm? With BST's I would easily get two below £100 or go for something different and spend up to £100 on one eyepiece? Have a wide range of focal lengths and ratios over my three scopes, do I plan for different eyepieces per scope or stick to common eyepieces? Before anyone suggests Televues, I'll need to spend a fair bit on the wife before they turn up in the post? unless of course someone knows of deals going round

      Heyaaaa. Its been a long time!(not really its been 5 days :P) its me againn ! As you have seen by the title i am in a delleema (misspells ftw) between eyepieces
      Here are 2 eyepieces i can buy with my budget
      https://www.amazon.co.uk/Prettyia-Eyepiece-Telescope-Skywatcher-Astronomy-Multicolor/dp/B012JC3274/ref=sr_1_9?s=electronics&ie=UTF8&qid=1547060539&sr=1-9&keywords=prettyia+eyepiece (ik its 3 eyepieces but there is no other pack that delivers to my location than only includes one)
      and https://www.firstlightoptics.com/skywatcher-eyepieces/skywatcher-uwa-planetary-eyepieces.html
      But with that excact same money i can buy this! 
      https://www.firstlightoptics.com/skywatcher-eyepieces/sky-watcher-sky-panorama-eyepieces.html
      holy moly 82 degrees!
      Something is telling me to ditch the cheap Zoom eyepiece and the planetarys and  just buy the panorama eyepiece from the money i would use on the planetarys and the 8-24 instead.
      Does anyone have any expirience with that particular price range zoom eyepieces or the planetary or the panoramas?
      Also can you reccomend me a size (7mm 15mm)?(there is no way i m buying the 22mm one) my main targets will be dsos as well as planets so. I will be using those in my Celestron firstscope and in my future ( i ll buy it in like 3 months lol Skywatcher heritage 130p)
      telescopes: Focal lenghts :Current telescope:Celestron firstscope 300mm FL
      Future telescope:Skywatcher heritage 130p 650mm FL 
      To sum up:Get the 2 or the panorama?
      If i get the panorama which lenght?(7mm or 15mm)? (i want a size that compliments planets and most dsos ) ( i live in the southern hemisphere {so no orion nebula for me} (my favourite DSO)   for now atleast) 
      Thanks for your time !
      Kronos!
