After applied the corrector, I can't get a good focus using my 2" barlow eyepiece along with 23mm eyepiece. Please help.

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 magnification and use the reducer/corrector when you want more light (for dim objects) and less magnification

When you apply the corrector you will have to dramatically change your focus setting. Because of this, I recommend not attaching the 2" Barlow lens initially. Then focus your telescope with only the 23 mm on a bright object. After that attach the Barlow and you may have to focus again.

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.

You are not doing anything wrong. To see the shape, you need more magnification. I got a Barlow 2x shorty to go with mine which doubles the magnification. That will enlarge Mars so it's a bigger dot.

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.

I have a Nikon D700, had the same problem. The focus plane is too close. The only way I got mine to work is in combination with an Orion Shorty 2x Barlow. This forces a 2x multiplier when you may not want it, but it does focus with it attached along with the Universal camera mount. I am currently investigating just how much extension is added by using the Barlow and will be looking for an extension tube without magnification.

Make sure you're using the correct lense. Don't use the high powered one yet. Use the lowest power. Point it at a far away house's window and get it focused. Next get the spotting scope calibrated on that window. Once you've done that, point it at the moon and focus on that. Sounds like you're just way out of focus.

Yes, I bought an Orion 2x 1.25 in Barlow lens and have used it with the telescope

You have to use the correct metal ring, included in the kit, for the lens to connect properly. All of the rings do not work, so look them over carefully and choose the correct ones, put the others aside so you don't get them mixed up.

If your telescope is of the Newtonian type you might have a hard time getting the image to focus, or even not being able to focus at all. If this happens you would need a different adapter with a Barlow lens or to move the main mirror inside the telescope.

You'll need to either use a Barlow, get a low profile focuser, or move the primary mirror further up the tube. This isn't a problem with the camera, rather it's a function of the focal plane of a Newtonian telescope relative to the size of the secondary mirror. I have used a TeleVue PowerMate 4x with some nice results. A cheaper 5x Explore Scientific Barlow should work also.

the scope was trouble for me as well, i bought a simple red dot holograph and put it on there. worked better.

Hey Aaron, common mistake. What you need to do is set the actual aperture on the lens ring to 22 and the lock it on that value so that the little red line aligns with the 22. This happens because you are using an older non focusing lens on a newer body. Problem solved. Have fun, that is a fantastic lens.

It is equivalent to a 5mm eyepiece so it already is about all you can use. The answer is yes you can use a 2x multiplier, I did but even with the electric focuser on the telescope it was very hard to get focused and you can not see any useable gain.

Kenneth, I have an Orion XT6 that has a 1.25" rack and piñon focuser. The Barlow works well as well as all eyepieces and filters.

I have the exactly same problem. Don't know where to buy the correct eyepiece.

I think maybe they sent you the wrong speed ring. All I did was remove the reflector and put the speed ring on. It took all of 10 second to do.

Try adjusting the diopter adjustment on the viewfinder- likely was off. Should view and record in focus.

I could not get my Celestron XCel series 2X Barlow to focus. It was way beyond the focuser's travel and others have noted this but apparently Orion's Shorty 2X Barlow will work with this telescope as well as GSO 2x barlow from Agena AstroProducts. The useful magnification on this telescope is 200X but that is probably counting on optimum conditions. For planetary views with average conditions with a 100mm telescope, magnification of 100X to 120X are probably expected to be the clearest.
