It cleared things up for me. I will now go ahead and switch to a ETX-125 which seems to be a more competent and sturdy telescope. I hope to get the new scope before the 27th when our "red neighbour" swings close by :) Thanks once again! youv been a great help! :) "live long and prosper" //ÅkeMike here: I hope you don't mean the "Mars as big as the moon" August hoax.

Subject: Help regarding eyepiece(focal)DSLR shooting with Meade ETX-80, ETX-125 Sent: Sunday, August 11, 2013 04:42:07 From: firren fisk (email@example.com) Great site you have here! iv got lots of great tips from it. I have two question i was hoping someone could help me with. I have checked all the tips and trix on your astrophoto and DSLR pages but cant find an awnsers. Questions/problems: I currently own a ETX-80 and when i do astrophotography i mostly do it via the main eyepieceholder. My setup is the following: ETX-80 main eyepiece holder >> T-adapter with eyepiece tube(camera adapter with or without an eyepiece inside) >> T2 ring > Canon EOS1100D(T3). My problem is that i always have to use the etx built in x2 barlow lens to be able to get focus on the camera. Iv also tried removing the "eyepiece tube" from the t-adapter and mount the t-adaptor straight to the t2-ring to get the ccd sensor closer to the telescope but i still have to use the barlow lens to get focus... Might this have to do with the focal lenght? if so would a focal reducer help in this case? My other question is. I am about to replace my etx-80 with a etx-125 and i was wondering if anyone knows if i will get the same problem with that scope as with the etx-80? Will i have to buy and use a x2 barlow lens with that telescope also?. My setup is the following: Meade ETX-80, Canon EOS 1100D aka T3, Astro(same as OPT) eyepiece camera adapter(t-adapter+eyepice tube) and a T2 ring for my EOS camera. I have included a picture that helps explane my setup. Cheers from Sweden and thanks for a great site! //Åke Nissinen, Sweden E-mail: firstname.lastname@example.org
Mike here: I have the same problem with my ETX-70 and Nikon DSLR. The ETX refractor models have limited focus travel and getting a focus on a camera focal plane is difficult, if not impossible with many cameras. However, you should not have the same problem with the ETX-125. I have done a lot of astrophotography with my ETX-90/105/125 using my DSLR; focus hasn't been an issue.

Subject: Re: Meade etx-70at and Canon EOS 500D Sent: Monday, January 2, 2012 02:54:20 From: Christian R. Larsen (email@example.com) I made it work by connecting an angled prism to the camera mount. It works rather well and it enables me to put a Barlow lens in between. I don't know if this way of mounting has any disadvantages over attaching the camera through the eyepiece holder instead but I got a couple of nice day-time photos of the moon. Christian
