Just got a Celestron 127EQ &amp; have heard that a barlow can be "too good" and needs to be properly matched...would a 3X or 5X be better?

Mine works just fine. I don't understand "too good". The mirror is what matters. The telescope has a great mirror for the price. 3X is what I have. I like the zoom lens best. It is the easiest to work with.

A barlow is fine. I use the GSO Barlow that actually gives you two magnification choices...http://agenaastro.com/gso-1-25-2x-achromatic-barlow-lens.html

Yes it will do well with the 127 eq. Most telescopes use this 1.25 inch eyepiece. Good quality eyepieces can turn an average scope into an acceptable instrument.

Yes, you can see the Moon with the 09881 Observer 70 refractor! It comes with two eyepieces giving you 28x, 70x. You may want more magnification so we suggest getting the Orion 2x Shorty Barlow. It goes where you usually put the eyepiece and then the eyepiece goes in the back of the Barlow tem # 08711. If the Moon is too bright for comfort you might consider our 25% Moon filter that will screw into the silver end of either eyepiece Item # 05598. All the best!

Yes. It will. A standard length 1.25" Barlow would work just fine with this telescope as well.

It will work on the NexStar 130 GT but mainly for the Moon. The focal length is 650mm so Jupiter and other planets will be small. You can use a 2x to 3x Barlow though to double or triple your focal length. Then the main issue becomes how well does the scope track. With the small field of view that you get with this camera it is hard to find and keep the planet in sight. You can ask your question at Cloudy Nights and get many more people trying to help you.

Hello, First issue is the use of a reducer/corrector with a barlow multiplier. The two lenses are working against each other to no effect. Use the eyepiece alone or use it with the reducer corrector for lower power (wider fields of view) or use the eyepiece with the barlow for much higher power (smaller fields of view). If you have the Celestron Edge telescope I do not believe the reducer/corrector will work correctly. Hope this helps.

These filters DO fit, as the 127EQ (I have one myself) has 1.25" eyepeices. The kicker though, is that our eye pieces do NOT have any threads (the eyepieces that come with the set). I've been told by Celestron to hold the filter between my eye and the eyepiece. Sigh.Best thing to fix that...get a different and better eyepiece.

The corrector is a "reducer" which means it's purpose is to take in more of the sky.The barlow's purpose is to magnify the portion of sky.So putting them both on the scope is defeating each of their purposes.Use only the barlow if you want GREATER magnificationand use the reducer/corrector when you want more light (for dim objects) and less magnification

Saturn's rings are always a treat! Glad you saw them. A 2x barlow and 4mm eyepiece will give you 200x on this scope, which is about the theoretical maximum usable magnification for a 100mm aperture scope like this one (about 50x/25mm). But in my experience with these smaller scopes, the image is rather poor at maximum magnification; you can see something, but very dim and very grainy, for instance. For my eyes, the max usable magnification is closer to 40x/25mm..... I think it's fun to use the max magnification (esp. on the Moon!) But I usually get the most satisfactory viewing at a lower power. Enjoy your telescope! Saturn's rings are always a treat! Glad you saw them.

You need to culminate your scope . Im not sure what a 24/8 'm lens is . The scope comes with a 25mm eyepiece wich works really nicely with a 2x barlow . Try a 17mm or a 10mm . Dont expect it to be to big though remember how far away it is . But even with a 2x barlow and the 25mm eyepiece it comes with you will still be able to see the cloudbands and 4 of its moons .

You can connect camera to this barlow. you need a 1.25" universal T adapter and the correct T ring for your SLR or DSLR. Google it both Meade and Celestron make one. http://www.celestron.com/astronomy/celestron-t-adapter-universal-1-25-in.html

Chis... Your question is incomplete. The Universal T-Adapter has two applications. Visual observation and Astrophotography. For astrophotography, the T-Adapter attaches your camera to the visual back of the telescope and proides a focal-plane imaging system. No occular (eyepiece) is used. However the built-in Barlow lens provides an effective doubling of your telescopes focal length (i.e. a 1000mm f/10 SCT is effectively a 2000mm f/20 "lens"). For visual observing, the adapter will accept any 1.25" occular. The Barlow lens is removable for either application. For eyepice-pojection astrophotography, consider the Tele-Extender Deluxe. This will allow you tu use most 1.25" occulars as a projection lens. Not that the optical speeds of this approach is extremely slow. f/30 would be good. So it is only practical for very bright objects (planets, moon, etc.).

Yes, but you may be disappointed by the result. The barlow lens will boost the magnification with the 10mm eyepiece to 80x. Even if everything in your scope is in good alignment you'll probably find that the picture at 80x is noticeably fuzzy. Unfortunately, not every one of these telescopes seems to be aligned well at the factory, so you may find the 80x image in yours is much worse than that. The Travel Scope 70 is really made for low-power views, and Celestron is to be commended for not making exaggerated claims about high powers. The 20mm (20x) and 10mm (40X) eyepieces that come with the telescope are good choices. Yes, but you may be disappointed by the result.

Try the ocular first and if you need more power then add the barlow. Personally I do not like barlow lens and you will have around 155X with the 8mm. That is a nice power for the C-5. Generally my oculars cost around $350+ each and are a single mm because the lower priced oculars degrade the optics far to much for me. The C-5 is a fine instrument but most cripple it with poor quality oculars.My C-5 can handle a 4mm ocular beyond that the quality is lower than I generally want and remember it is only a 5 inch instrument. If you want more power then get an 8 inch interment.

The 52303 Regal Refractor has a focal plane that is very deep in the scope. Therefore, you have to use an eye piece that has a deep set focal plane. Celestron has specific eye pieces for that scope to match it. In other words, the typical 1.25 inch telescope eye piece will not work with it. So, I suspect, the typical barlow lense or magnifier may not either. You can email or call Celestron, or talk to one of the bigger astronomical telescope retailers to find out for sure though.
