I have stumbled upon a very interesting site, upon seeing their products I searched them on SGL, and they seems to have a good reputation, even FLO sells it! I am interested on many of there products, some will be asked in a other thread, so here are some of those questions: 1. Can I see details on the sun with this kit, if not can I see a solar eclipse safely without solar filter? (Link: https://astromedia.de/Der-Sonnen-Projektor) 2. Is this a good, useable telescope? I am going to observe widefield stuff with this! (Link: https://astromedia.de/Das-Newton-Spiegelteleskop) 3. This is a really stupid question, but can I project a bright space object (Such as star clusters) to a screen with this kit? (Link: https://astromedia.de/Das-Kleine-Galileo-Teleskop) 4. Can I create a eyepiece with these lens (specifically plossl's) Link: https://www.astromediashop.co.uk/Components.html, Look at the acrylic glass section) Other questions will be asked in a other thread, thanks for reading! Clear skies!

I recently found this: https://tejraj.com/multi-coated-zoom-eyepiece.html So, is this worth it? I am used to 25mm kellner (and its fov), but the 10mm is way too small, and the idea that I might do planetary, doubles and globular clusters in a single eyepiece is pretty exciting, and I can only get two plossl with that money so is this a good zoom ep?

Hello, This is my first post. I bought a used Celestron 127. It's in great shape, and included all the accessories. The telescope was put together already. My only problem is erecting 20mm eyepiece wobbles/there's no way to secure the eyepiece inside the focuser. I've looked through the manual and checked online, however I can't tell if this is normal or not. Photos of what I mean I only found one post on another site where someone was looking for a part. I took a screenshot. I have all the pieces in the picture. The second picture I took of the inside of the focuser. The knobs on the focuser do not seem to do anything. Am I missing a part? I thought maybe someone here might know. I haven't had much luck. Thank You!

Finally got my Maplins case and yes, I went a bit crazy over Xmas and now have a nice little collection of 82° Explore Scientific Eyepieces :) I have yet to go outside with these new EP's as of yet, I cannot wait to give them a run! Got other little bits in there...some filters (UHC / Moon & Neodymium), Baader x2.5 Barlow etc. -
I’ve had this telescope for years. Used it as an astronomy educator during my undergrad. It was always a hit with the kids, showing them the moon. For the last few months, however, the moon is blurry. The coarse adjustment knob focuses it some, but not enough. I don’t know what I’m doing wrong. I don’t think I’m doing anything different than before. I have the diagonal in and the eyepiece in that, and I don’t know what else to do. Somehow, however, putting my phone camera over the eyepiece provided a clearer image in my phone. What do I do? I hope I can fix it…

Sybony Redline Eyepiece 6mm - Planet Killer?
refractor2345 posted a topic in Discussions - Eyepieces
So, after seeing some positive reviews on the Sybony Redline Eyepiece (6mm) is worth for planets is it good, for it's cheap price or it is bad. I will be using my 60mm f/11.56 refractor and 70mm f/10 refractor, so is it a good combination? -
Hi there! i bought my very first telescope but it was second hand and the eyepieces were missing. it’s an AstroMaster 70 AZ - i’m hoping to get good views of the moon/jupiter etc so i was wondering what eye piece everyone would recommend? very thankful for any help given! 😅 - bri -
Hey everyone I am very new to everything to do with astronomy/looking through a telescope and I have recently bought my first scope (a 8" dob) which came with a 25mm and a 10mm eyepiece but I am looking to upgrade but don't know what is good. Any help or advice on what eyepieces I should be looking at buying would be much appreciated (budget is anywhere form 0 to 100 pounds per eyepiece) -
Why there's black line around in my view 20mm eyepiece? Celestron ExploraScope 70AZ

Hi, I know that there has been a couple of threads on how to collimate a newtonian, more specific, how to center the secondary mirror under the focuser.I bought mine "Concenter eyepiece" for almost a year ago and can't praise it enough - it makes centering the secondary a breeze.Have anyone else tried this? What is your opinion?I have also read that some have questions of how accurate it is? - I might not know the answer to this question, but what I do know is that after I have been centering the secondary with the Concenter eyepiece, I finish of the collimation with the Catseye XLKP and Blackcat. The small adjustments I have to make of the secondary after adjusting it with the Concenter eyepiece tells me it is very accurate. It is just the absolute finest adjustments i have to make afterwards.I have made a video of how it works and how it looks like when I am collimating my scope. (10" f3,4 astrograph)Best regards, Daniel

In market for a good quality, reasonably priced long focal length 1.25 eyepiece to increase fov and help locate and view large objects. Celestron makes a 32mm for @$45.00. Is it any good? Price seems too good to be true. What are good quality/price options? -
Baader optical wonder solution is practically Isopropyl alcohol. Instead of £12 for a 70mL of it, buy a 1000 mL of Isopropyl alcohol for £22 (before pandemic it was only £5). They have also smaller bottles which will be cheaper of course. The Baader solution and Isopropyl alcohol don’t remove the toughest of fungi on optics, only a few of the less deep set ones can be treated with them. I have used both for cleaning eyepieces and on certain stage of cleaning several 8 to 12 inch mirrors. They both worked identical. When applied through an optical cleaning fabric, they remove ( dissolve) fatty oils and fingerprints on optical surfaces. I had cleaned a 12 inch mirror once which for some unknown reason had ice cream stain on it (cleaning followed standard operation procedure for cleaning coated aluminised mirrors). -
Hello, I am having a problem with a relatively expensive flat field eyepiece in a combination with a newtonian reflector. I am unable to achieve proper focus with that eyepiece because when I focus it on axis, the edges are blurry. When I focus it at the edge, the center field is out of focus. I don't want to mention the concrete type of this eyepiece because I received it with a spot on the bottom barrel, therefore I cannot be sure whether it has been dropped. This eyepiece has very good reviews on this forum. Optically it looks good and there is no rattle. My question is whether these flat field eyepieces are usable with newtonians as these telescopes doesn't generally suffer from the field curvature. Many thanks for help. -
Hi, I'm just wanting some advice on the eye relief and the quality of the 6mm Omni ep. I have a Nextar 127slt MAK. Can someone please tell me if I should buy it? Thank you, Spacecake

Gt my telescope based on recommendations here years ago. Its getting dusty though. Really just want to see as many planets in solar system as possible please. I read plenty but its too much to remember sorry. Struggled just looking at the moon Most things said barlows are a stepping stone. Can someone point out an eye piece on first light optics or something similar in UK please. Its for me and my 6 year old space obsessed son. Also a polarising filter if there worth it. Is a collimater cap as easy as a laser? I wont get round to making one so ill buy. Last step would then be plumbers tape on the eyepiece threads right? Thanks -
Hi, i have made a video where i show a coople of eyepieces that i use and like, and also show how a barlow works, compared to the "Powermate" from Televue. And how is the FOV affected when changing the magnification with different eyepieces? Feel free to comment and give me feedback - I hope you like the video! /Daniel -
Hi everyone! Like a lot of new amateurs I am completely overwhelmed with the choice of eyepieces. I have a Sky Watcher 250P Classic on a dob for visual astronomy. I have recently purchased the Hyperion IV 8-24mm zoom (with 2.25 Barlow) as my general roaming around EP. Now potentially looking for a high powered EP with large FoV to get those detailed views of planets and DSOs - the question is which should I buy? I was thinking something in the 2.5-6mm range and happy to go up to say £250 price point for the right EP. So, what is the wisdom? A 6mm and Barlow, or some where between 2.5 (pushing the scope) and 5mm without Barlow? Thanks! Lee

Hi, I have been enjoying using the Celestron AstroMaster EQ90 over the last couple of weeks, mainly on the developing moon until it got too bright. But I got seduced by a secondhand bargain, (I hope), in the form of a Skywatcher 130/650 Newtonian on a eq2 mount with an old version of a motordrive. After decontamination to be allowed into the house, I've cleaned it up and was pretty pleased with the views of the Strawberry moon last night, just using the small opening in the tube cover, I'm still waiting for my moon filter to be delivered. I can't find much info on the scope. Can anyone tell me if the primary reflector would be a parabolic and if not does it matter that much. The primary mirror is pretty dirty, actually had a dead fly stuck on it, I carefully removed the holder and mirror and gently blew the fly off and hopefully some of the dirt with a very low powered airline. It's still dirty but the views of the moon and some of the stars seemed good to me. How dirty can you let the mirror get and what effect would I see to know I should clean it? Also the eyepiece holder is threaded on the outside at the 'top', is this for attaching a camera T ring directly to? Hopefully pictures will attach. Graceful for any advise.

Does anyone who has one of these zoom eyepieces know if there is a t-thread hidden under the twist-up rubber eye-cups like there are on some other zooms? I don't have a zoom in my set yet and don't want to break the bank. I just aim to use it mainly for visual e.g. being lazy with one 'no faff' eyepiece or when I'm being more dedicated, scoping out the seeing at different magnifications before changing to a dedicated eyepiece. I'd only use it for occasional photography but would rather buy one with a T-thread. For reference here are the different branded versions I can find: OVL Hyperflex version: https://www.firstlightoptics.com/ovl-eyepieces/hyperflex-72mm-215mm-eyepiece.html Skywatcher Hyperflex version: https://www.365astronomy.com/SkyWatcher-HyperFlex-7E-7.2-21.5mm-High-Performance-Zoom-Eyepiece.html I had read in the previous thread that the Lunt version of this zoom is also generic but the only one I can find looks quite different and is twice as expensive and has a different field of view so not sure about that? https://www.firstlightoptics.com/lunt-solar-accessories/lunt-125-zoom-eyepiece-72mm-215mm.html Thanks for any feedback (or any other recommendations for circa £100 zoom lens that might have a hidden T-thread)!!! -
Hello everyone I've just bought my first telescope, a 10 inch Dobsonian, Saxon brand (same as Skywatcher). In daylight I've collimated it with a laser collimator. Also in delight I've centred the finderscope on a house on the horizon (probably 5 km away). The image is inverted and the left side appears on the right. I understand that's normal. The house is also centred in the eyepiece and the view is inverted and left appears right, as with the finder scope. BUT the horizon is at about a 60 degree angle ( see pdf sketch attached). Is this normal? Or am I doing something wrong? Or is there a problem with the telescope? Many thanks in advance Susan telescope views25082020_2.pdf -
Hi all I’m getting back into the hobby after some time away I always seemed to spend a lot of time switching between eye pieces so this time I was thinking of having just 4 ep to choose from as opposed to 12. I have a an 8”sct and was thinking of getting the Explore Scientific 82° im considering the following 30mm 18mm 11mm 6.7mm first do you think these particular e/p will work well with this scope and does the choice above sound sufficient. regards Lee

Hi SGL, is there any plugin or setting that can (more) accurately depict views through an eyepiece? I'm aware of the oculars, but what I'm after is the shimmer of the planets, dimming of DSOs when using smaller scopes, planetary detail dependent on telescope size etc. Thanks -
Hi i own Celestron 130EQ which comes with 20mm erect EP and 10mm EP.... i bought a GSO ED 3x Barlow... The focus is not very sharp while using Barlow... Is it the EP at fault ???? Is it worth upgrading to Kelner or a Plossl ????

Hi all, With the advice I'm getting here, I'm planning to start my hobby with Skywatcher Maksutov 102 telescope. There are several models with this optical design, BUT it looks like they all sold out! Almost all... FLO still could sell a Mak on the older EQ2 mount. https://www.firstlightoptics.com/maksutov/skywatcher-skymax-102-eq2.html What would yo say about this combination - is it an obsolete scope, or the same as modern versions? How it this mount? I gather it can be also used as Alt-As, right? And one more question, with this long focal length I think as a beginner I'm running into an issue of finding objects with it's FoV. What eyepieces would you recommend to add immediately to this scope? A good price/performance would be great! For instance, should I add a 0,5 reducer or a 35-40 mm eyepiece, should I immediately replace 10mm? I've read the great post of @The Warthog, so have an idea what focal lengths I'll need (10, 15, 25, 40). Just want to check your opinion what could be ideal price/performer. Thank you!
