Would the Hyperion 8-24mm Click Stop Zoom work well with this? Would adding a Celestron 93529 X-Cel LX 1.25-Inch 2x Barlow Lens & the Hyperion work?

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.

It will work just fine. You may want to invest in a quality eyepiece depending on what it comes with. I got the Celestron version and was mich happier when I put a plossl eyepiece in, but the Barlow fits any 1-1/4 inch

Hi bruno, I mentioned a rather stiff zoom ring starting around 100mm and no it didn't get better. I did exchange it and the new copy was better but still a bit stiff, the low light characteristics on the replacement improved just a little bit . This lens for me pretty much spends it's time in a drawer unless I'm going somewhere outside that requires going light and the photo's taken aren't important. It's rarely on my camera.

The 70 Travel Scope can handle a "Shorty Barlow" from the top of the diagonal. The Scope is 70 mm, so It's Magnification Max is 140 power. Your 20 delivers 22.5 Magnification, the 10 mm 45. The Scopes power is the ability to not surpass 2 X the MM appeture (front Lens Diameter) so 70 X 2 +140. A Two times barlow would double your current numbers; a triplet would get you 135 Power with your 10 mm. That's 5 mm under the scope capacity so as not to darken the Picture. This Scope is great BTW, we used It to film the Venus Transit across the Sun and other Dark Sky Objects, great for Landscape photography as well (on a budget :) Though make sure It's a "Shorty" Barlow Lens, some are too long to go into the "top" of the diagonal (you need the Diagonal because It's part of the 450 mm Focal lenght ) from the "tube side" you won't be able to focus. Celestrons shortys work well as Meades. Hope this helps.

I've never seen two barlows used at the same time but don't let that deter you. This is an awesome barlow to use with large aperture scopes. I use it on my Orion Xt10 Classic Dobsonian with a 25mm lens. I use it with viewing Jupiter, Saturn, Mars, and all the other planets. With where I am (near a city) I lose some clarity with it but its magnification is unrivaled in my opinion.

What type of scope were you using it on? My DSLR comes into perfect focus. You really do not want to use this to image Jupiter anyway - you should use a 4X barlow, to make it bigger, not a focal reducer to make it smaller.

No, that's not true. The focus ring must stop at either end of the focal range. If not, the lens is faulty. My 24-70mm lens works perfectly as designed. Both the zoom and focus rings STOP at either end of their intended range. Hope my answer is helpful for you. Regards,Tam

Yes, these accessories will work with that telescope, but you might be better off spending the same money on two Celestron X-Cel LX eyepieces. The X-Cel LX are of higher quality and have longer eye relief, making them more comfortable to use. Consider the 9mm and 5mm, yielding 111x and 200x magnification, respectively.

You can get eye pieces that provide more magnification but for the XT4.5 it won't enhance your viewing. I would instead get a Barlow lens to double the 2 you already have as I found the 10mm w/ Barlow is much better than buying something like the 6.5mm I picked up. In fact, I find I use the 25mm w/ the Barlow more than I do the the 10mm.

That isn't how this is designed to be used. This just threads into the T Ring for prime focus. For what you are wanting to do you most likely need a zoom eye from Celestron that has the T Thread built in under the eye relief for example http://www.amazon.com/Celestron-93230-24mm-1-25-Eyepiece/dp/B0007UQNV8/ref=sr_sp-atf_title_1_1?ie=UTF8&qid=1371435550&sr=8-1&keywords=93230 .

This is the best lens in the world (I say with prejudice) - take one of your zooms, set it to 85mm and see if THAT focal length will work for you. If so, BUY BUY BUY. It's so razor sharp. Feel free to ask me more.

I don't see why not. I use mine on 17-40mm 24-70mm and 24-105mm and I am referring to focus and not zoom.

I have the same lens bro and it went well.But you'll have to use the lens on its longest zoom (135mm) to get the macro effect.It's not a macro lens, but it's quite handy if you need to shoot a big closeup.

It will work with any standard 1.25 inch eyepiece adapter or focuser, but i second the previous answer regarding tracking. I suggest downloading Stellarium (free planetarium software) and entering your telescope and the sensor specs into the telescopes plugins so you can see what the field of view would be in you 80 mm, and how quickly objects move out of that field of view. If it's too small, and you don't have mount that is tracking the sky, you might end up just being frustrated.

I'm using it with my Nikor 1-300 and 18-200 lenses. Works like a charm. I'll likely sell my micro lense. Much better than teleconverters, as there is NO change to f stop.

You will need a T-adapter as well as tne Celestron 93230 8 to 24mm 1.25 Zoom Eyepiece (this eyepiece is the only eyepiece that allows you to focus and change the focal point for your camera which is mandatory for higher end cameras. Note: This scope is not meant for astrophotography but is still a very nice telescope for the price.

I'm not sure I understand what you mean by "digital zoom"?. With the 14 - 42mm X lens with electronic zoom I can use "manual focus". I have not tried other auto lenses which have the manual zoom ring in addition to the electronic zoom.
