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! -
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?

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!

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? -
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… -
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 -

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. -
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 all I am putting together an oil-bath auto-collimator rig to check over my reflectors. It occurred to me to use an off-axis guider body and its pick-off prism to feed the light source in - no heath robinson pipe assembling. Then I can just use a positive eyepiece where the camera should go to examine the ronchi lines to estimate the optics quality. This raises the question - I would need to put the ronchi screen on the telescope side of the prism - say in a filter mount . Is this too far from the source ? Is the source to ronchi screen distance important ? Cheers Mike

Hi All, I've been getting along reasonably well with observing but I find the glasses really annoying having to take them off most of the time. Are there any recommendations for long eye-relief eyepieces suitable for glasses wearers? Thanks, Neil.

Hi all, I was just wondering... I've been looking for eyepieces to do drift alignment with, and as per this video: http://www.andysshot...tAlignment.html and after trying out with my own 5mm eyepiece (without reticle), I wanted a 5mm reticle eyepiece. But searching it turns out there are practically only 12,5mm illuminated reticle eyepieces... The 5mm Orion seems to have been discontinued... Anybody have any idea why this is? Did the 5mm cost too much? As I see it a 5 mm would do nicely, because one easily sees the direction a star goes, when turning off the motor drive, and I'm guessing it would also be better for detecting the drift. More so than with a 12,5mm... Thanks for any ideas, thoughts! Gerhard.

barlow lens Barlow Lens Help
BetelgeuseAlpha posted a topic in Getting Started Equipment Help and Advice
Hey guys I'm an aspiring beginner astronomer and observer, and I recently inherited my grandfather's old telescope. It is a Meade Quartz with the LX Pulse drive. Only one problem, he left me with no instructions. I learned about the Barlow lens, and how it magnifies the normal eyepiece, the only problem is I have no idea how to attach it. The hole where I normally fit an eyepiece is far too large for it to fit. The size of the hole can fit a 26mm lens. Is it because I have brands mixing and it can only fit a Meade Barlow? I appreciate the help. -
Hi all, For the first time in my life i have bought a telescope(celestron astromaster 130eq)..So iam very intrested in seeing my favourite orion nebulae , How can i get a closer image of it like shown in many pictures..Is it possible to see very closer from this telescope and how the color comes? is the color of nebulae is fake or real? What eyepiece can i use to see the distant deepsky objects very close and clearly... Thank u....

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 ????

Following a talk last night on the use of colour filters in observational astronomy by Alan Heath at my local society, I looked for something on the history of eyepieces. I found this comprehensive document which does a pretty good job [and a detailed one] of working through the different groups of eyepieces there have been in the last hundred years or so. It's quite long, and there are lots of equations and the like, but these can be skipped over. I simply found this on the internet, I cannot take any credit for it. http://www.brayebrookobservatory.org/BrayObsWebSite/BOOKS/EVOLUTIONofEYEPIECES.pdf James

Hi, After a lot of research I purchased my first advanced telescope a 12inch Orion SkyQuest Open Truss Dobsonian. Being into astronomy for years now this is the first gaint telescope I am using. Today was first light and I was rather confused as to what I was seeing. Comparing my tiny 4inch view of Jupiter with the view from this 12inch; it was nearly similar! So the question is which eyepieces should I use to get better detail? I have a 28mm, 32mm, 15mm, 6mm etc. and a Baader zooming hyperion. I viewed Jupiter from both the telescopes using a 32mm wide angle eyepiece. This is probably a really rookie question so go soft on me Which eyepieces and of which make should I attach to fully utilize the capability of this telescope? I tried the Baader and the 15mm and the 32mm for seeing Jupiter tonight. Any help would be highly HIGHLY appreciated. Clear Skies, Div

Hi all, I am currently split on my next purchase for my telescope (Skywatcher Startravel ST120). As you can see from my list of equipment I already have quite a few EP's, yet FLO has a good offer on a 5mm Skywatcher SWA 70 degree EP (http://www.firstlightoptics.com/clearance/sky-watcher-swa-70-eyepieces.html ). However, I was also considering getting a starter imaging camera from Celestron (http://www.firstlightoptics.com/clearance/celestron-neximage-solar-system-imager.html). I like the EP as it fits both 2" & 1.25" diagonals which I have, and think the quality of the EP will be much better than the stock 4mm EP I have already, plus with the larger eyepiece lens too will make it much easier to observe through; yet I like the idea of the Celestron camera to fit into a 1.25" diagonal which will allow me to take images through the scope (via a laptop) of the moon & the planets (I know it wont be able to do DSO's at all), and the magnification of the camera will also be similar to the 5mm EP also. So before I fall on one side of the fence or the other in the next couple of days, perchance anyone has had any experience with these items and give any feedback (pro's & con'S) to help make that final decision less painful? Many thanks in advance! Gus

I am considering this eyepiece for my refractors. It would be used with and without Baader barlow 2.25x. Has anybody tried this combo? In the past I tried the BCO 10mm, but I let it go.

Hello everyone, Bit of a backround: I've been a keen stargazer when in my teenage years, then couldn't pursuit my passion, but recently, in my forties, it hit me again, as I moved and life is good (South facing large garden, obstructed only from the North by our house, but then I just move the scope further and viola!). Started with 90mm refractor, but was always thinking of reflector. Long story short, I've got my SkyWatcher Star Discovery 150P GOTO a week ago. Bought it second hand, very good condition, and good mirror. Have got two nights stargazing, cought cold and I AM LOVING IT. Now I would like to get me a nice wide angle ep for DSO spotting. The scope is 150mm / 750mm f5. I've done some reading obviously, and Explore Scientific 82 degree series have all good reviews and fit within my budget. I can afford only one, and apparently the best for DSOs is the one that gives 2mm exit pupil. Now, for my scope that would be 10mm piece, and that is not within ES 82 degree range, so it's down to 11mm (2.2mm exit pupil) or 8.8mm (1.76mm exit pupil). My question is: which one would be better for my rediscovered passion? I'm gonna be using that ep for faint mostly. Thanks to everyone in advance for any kind advise. -
Hi,I'm looking for experts advice about eyepieces. For constellations and general obseration looking for 40mm eyepiece ,just not decided which one is better for 250mm Newton and 180mm Cassegrain. Have aimed on Meade 40mm SW and TeleVue Panoptic 41mm. Finally or at the beginning must ask for advice if those 40-41mm 68 ° eyepieces gives more wide view than 30mm ES 82°? Appreciate experts advice.

Hi everyone! My telescope came with 2 eyepieces, a super 25mm and a super 10mm. The other day I was looking at the moon (using my super 25mm and a x2 Barlow as always) and I decided to swap round my super 25mm to my super 10mm and it was a much better image! I could see right into the surface and view the craters inside the craters! Can someone please explain why the smaller diameter eyepiece works better? Thanks

I am the happy owner of an ES 82 degree 18 mm eyepiece that I use together with a Baader MPCC coma corrector on my SW 200 mm f/5 Newtonian. Until now I have been using the CC directly attached to the filter thread of the eyepiece, which I know is not correct. I now wish to buy the corresponding spacers so to be able to use the optical system correctly, but this is seemingly more difficult than I first supposed. According to the CC specifications, the distance between the flat surface and the focal plane (camera or eyepiece) should be 55 mm. I have verified this when using the CC photographically and that worked fine. If one removes the T-2 adapter and uses the M48 thread instead, as I do for use with the eyepiece, this distance becomes 57.5 mm. Thanks to this table in a post in Cloudy Nights I was able to figure out that I need a spacing of 32.5 mm between the coma corrector and the eyepiece. The post includes some references to spacers, but aside from the Baader ones (28 and 14 mm, see here) I am having trouble to find suitable spacers in European retailers that would add up to 32.5 mm. This is why I would like to ask you for help. Has anyone solved this problem before? If so, how? Where can I buy spacers suitable for adding 4.5 mm optical path to a system with 2", M48 threads? Thanks in advance and clear skies! -
Hi, I have a skywatcher 200p dob and was hoping someone would be able to recommend an eyepiece with a wide field of view that would help finding objects and observing larger objects like the Pleiades. I have had a look at an explore scientific 30mm with 82° FOV, but was unsure if it would be good with my scope. Thanks Katie

Hey guys!i need to make this quick! I want to get a new 6mm eyepiece.I have a 8" f6 dob and i want to get a nice 200 mag and put the telescope to its limits at 400x The most i ve seen with is 240x for Jupiter and Saturn .i ve heard they looked stunning at 400x and i am keen on trying it.Ive got my eyes on a 6mm Skywatcher UWA eyepiece.and i have a Bst Starguider 2z Barlow lens.And i seem to be having problems with my 8mm Bst Starguider (300x in total).the bst has a 16mm eye relief and a 21mm lens diameter,but when i barlowed it and look at the moon yesterday,it was hard finding the right spot to look through the eyepiece and when i moved the image disappeared.I dont know if it will have that effect on planets,when I looked at mars it was fine but i definitely want to avoid that from happening again.Will it happen? The Skywatcher eyepiece i want to buy has a 16mm eye relief too.I dont want to make the same mistake now , i want a 6mm eyepiece at the price range of 50-70 euro either from flo or amazonuk.If the Skywatcher will have similar results,can you suggest another one?
