Fitted straight to Hyperion and couldn't get focus on Jupiter or Moon on either the 2" or 11/4". Had put some grease and loosened the focuser locking knob made it easier to adjust but still no joy. Took it back home and Hyperion had the 1.25" adapter fitted to which Barlow with its converter were attached. After removing the Hyperion 1.25" adapter, Barlow fits straight on with its converter. This makes it usable up to around 9mm (18mm/2). At higher magnification the focuser would need to extend more but it's at the limit. Need to think about 2" collar to let the Hyperion slot out fur

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 SGL, My lovely wife bought me a SW Explorer 130 with the basic RA drive for my 40th birthday 8 years ago, and I've enjoyed using it on and off ever since. I've started getting more into it - it's a great beginner scope, but I'm - like lots of others on this forum - looking at upgrading. One of the things I found tricky with the scope was getting the focus just right at high magnification (I'm sure that's kind of obvious!). It does wobble quite a bit on the EQ2 mount when focusing. I get pretty good - if small - views of Jupiter, Saturn, (the Moon, of course) and have had hints of s -
I picked up a Celestron Omni last year quite cheaply and had originally been using that with stock eyepieces, which was fine. Since then I've bought a couple of BST Starguiders and a Hyperflex zoom, and I'm now wondering if I'd notice any difference with a better barlow (this is now being used on an F/5 150mm Newtonian). Otherwise, the pennies can be directed elsewhere. I'd not considered it before as the next rung up seemed to be around the £90-£100 mark, which seemed out of line with the rest of the spend. But I've seen some positive reviews of 3-element models in the region of £35

After receiving great advice from this group, I decided to purchase this TeleVue 2x Barlow! It's going on my Skywatcher Evostar Pro 80mm. I have an ES 6.7 eyepiece I want to use with it. Can’t wait to give it a go!

Hi Tonight I was looking at Jupiter and got some nice views with a range of eyepeices. The best image detail wise and for clarity of image was a 15mm, which on my 8" Evolution gives me appx 135X I tried using my Televue 2X Barlow which normally works fine. I can't remember exactly which eyepiece this happened with, maybe the 15mm or a 9mm, but when I used the barlow the planetary image would soon disappear out of the eyepiece. The mount seemed to otherwise be tracking OK although notice the planets seem to move out of the eyepiece view after a while. So did I have too much magnifi -

I had another go at imaging the shrinking Mars, this time without and with a x2 Barlow lens. The results are better with the Barlow, which is what one is led to expect. For whatever reason (probably bad seeing and/or low planets) when I tried a Barlow previously it just made the blur bigger. Equipment: C8 SE, ASI120MC, x2 Skywatcher kit Barlow element screwed directly into 1.25" barrel of the ZWO camera. This does seem to give x2 in practice. I did not use an ADC on the grounds that I shouldn't need one with Mars at an altitude of over 40 degrees. 3000 image video captured with Sha

Hi everyone, I was lucky enough to get a 12" Skywatcher Dobsonian (305mm/1500mm) for Christmas. It shipped with a 10mm Plossl and a 25mm Plossl, both 52° AFOV. Finally had a clear enough night to try it out and I absolutely loved it. I researched a bunch over the last year so I knew this was the scope I wanted should someone want to get me a really sweet gift before I grabbed it myself. What I didn't research at the time was accessories and equipment, something I've been doing relentlessly over the past few days. I'll primarily be viewing in the backyard until I find a great viewing -
Hello you wonderful people,sorry i have not been on here much lately,busy life and terrible cold/flu, i am considering purchasing a Barlow lense, and i would very much appreciate your thoughts and input, as a total newbie, i dont know very much, i know i want to get a 1,25 x2 barlow, but is it ok to buy a generic or should i buy a brand name and spend a little more, does it matter what i buy. I have seen them ranging from £6.00 upwards i was thinking of getting the celestron for about £25. Anyway thank you very much for taking the time to read and comment, best regards Dave.

Looking for a TV Panoptic interface for 2 inch Barlow lens. Can pay by PayPal.

Are these same as the Baader, or different lenses in a Baader body?

Looking for a little advice. I have an Orion 2x shorty Barlow that came with my telescope. It seems to be much harder to focus when I use that with any of my eyepieces than my actual eyepieces are. I have a new Orion 6mm planetary eyepiece, which if terrific, actually, but when I pair it with my shorty 2x, I can't really get a clear focus on it, which is a little disappointing. I am thinking of buying a TeleVue 3x Barlow, which is much longer. It seems like with a longer eyepiece like that, it wouldn't require so many micro-adjustments to try to get a good, clean focus. (I could be wrong -
Hi I have a Meade sct and I’m a complete novice and was wonder where to install my 2x Barlow lens. Thanks in advance for help

Expensive. Has anyone got/used a Zeiss Abbe Barlow? Are there lower priced equivalents proved equally as good?

Hi there, I am still new to amateur astronomy and astrophotography. I recently took my first steps towards moon and Jupiter photography. While I am satisfied with my moon pictures, I am struggling with Jupiter. I am a bit desperate, so I hope that maybe someone good give me a couple of useful hints so I can learn and improve. When shooting Jupiter without any barlow lense or eyepiece, I manage to get a sharp picture and am actually reasonably satisfied with the results (see attachments named "ok.."). I use Firecapture to shoot something like 3000 single images (mostl -

After serious thoughts, I decided to sell my Zeiss Abbe Barlow 2x as it is not getting used as it should. It is a top-notch barlow which can work from 2x (native) to 4x (using Baader T2 spacers). At 2x it is parfocal. This Barlow only weighs 103g. Barrel and clamp are 1.25". The 1.25" Baader clicklock also comes with a T2 thread, in case one wants to combine it with other equipment via T2 connection. It is in perfect conditions (as new really) and was bought new by me last year. Asking for £260 (70% the price of a new one), and this includes RM special delivery. Alternatively, £250 on col

While looking into the Nikon EiS 1.6x Barlow, designed primarily to go with NAV SW eye pieces, I found this pictorial comparison linked to by the knowledgeable Don Pensack.

This may be a dumb question but can you stack barlows together? like a x3 under a x2 or the other way, would it be x5 or x6?? I was thinking of getting a x3 barlow for higher magifacation .

Hi I have a Skywatcher 200PDS. I managed to get images of saturn, jupiter with the telescope and the ASI120MC-S camera. However, to get a bit more magnified image of these planets I got myself a Barlow Tele Vue 3x and Revelation 5x. I am having trouble with this setup and really disappointed now. I am not able to achieve focus with any of these barlows using my planetary camera. I have added extension etc. but no luck whatsover. I just see a blank black video preview in SharpCap. I have seen people using the same setup and getting good images out of those. Any help highly appreciated. -
hi, I am unable to wind in the focus on my skywatcher 200 to achieve focus when a standard barlow is between tube and camera. I am seeking recommendations on a shorter version Barlow (with t ring) so that I can gain focus on Jupiter, Saturn on the camera. As far as I can see it would appear that longer barlows are around 5-6 inches and the shorter units are 2-3 inches. This reduced length would likely deliver the space I need to gain a focus. Appreciate any advice on others who've no doubt overcome this issue. Neil -
I just bought a T-ring adapter for my nikon d3000 and want to connect it to my celestron powerseeker 127EQ, I have read some tutorials about focusing but can't understand it clearly.. (English is not my native language and there's no much info in spanish) SO I saw in a video that I can use a barlow lens to achieve focusing but I'm not sure if this works, I have a 3x barlow. Am I missing something? Is there any other piece I'm missing for achieving focus? I have seen many videos where they connect the t-ring to another weird tubes to enlarge everything but I dont know if I need -
Evening everyone. Quick question about eyepieces in simple terminology: I understand that the lower the number of an eyepiece, the more zoom it provides, and different makers provide different FOV. My question is that, for example, if I use a 2x Barlow with an 8mm ep, would I have a 4mm ep? (12mm+2x = 6mm; 40mm+2x = 20mm, etc.)
