  1. I have a 6mm and 20mm eyepiece and a basic telescope that we found at a yard sale for super cheap, with no extra tracking mounts, etc. I was able to get a great view of the moon, Jupiter, etc... I also bought a Canon T-Mount for $30 for my DSLR and was able to get some great shots of the moon recently. My total investment was under $50 probably.
  2. Thanks guys! I appreciate the encouraging words. I agree that the positive and encouraging ethos makes this site unique. I posted a couple weeks ago on the CloudyNights forum for the first time. The attitude was the exact opposite. The moment I made my first couple posts an overly aggressive moderator was picking at me for nit-picky mistakes I made in my post and tried to show how powerful he was. Then everyone repeatedly told me how my gear was inferior and I would never get a good image. They said it would be too dark and blurry, etc... This site is more friendly towards newer
  3. PS: Yes I think a single hair or piece of thread from my clothing must have made it's way onto either the mirror or my camera's sensor in the latter few pics I took. It wasn't there for the first 3/4 of the shots.
  4. I just wanted to post an update since many of you were helpful with tips regarding hardware for my lunar photography quest! I also want to give a BIG thanks again to the person who donated the 1.25 inch 2x Barlow lens to my cause! As some of you may remember, I have the equipment listed in my avatar below (Canon EOS Rebel XS and Galileo 700x76mm reflector telescope. I bought a t-mount and t-ring adapter from B&H recently but wasn't able to dial my focuser in close enough to get it in focus. The Barlow lens arrived in the mail today and even though it was 14 degrees outside, I bu
  5. Hey guys! Thanks thus far for the help with connecting my Canon DSLR to my Galileo telescope. I have a BIG update. Well it's big to me, probably not anyone else... This was just proof of concept, but... As you may recall, I bought a t-mount and t-ring adapter to connect my DSLR to my telescope. Thus far, I was unable to focus my setup and I figured I will need to buy a 1.25" 2X Barlow lens to remedy the problem... I was for the first time able to get my DSLR/telescope setup to focus. I took it out in the daylight and pointed it towards a hill in the distance. I first tried dr
  6. Thanks again for everything guys. I really appreciate the calculations, links, etc.. I now have an idea how magnified the image will be (about ~ 29X roughly) and how large it will appear in my camera sensor. (1/4 to 1/2 the screen) An update: I got my t-mount and t-ring adapter from B&H a couple days ago. I had to wait until 2:30am for the moon to rise so I could try it out. I first got the moon into focus without the camera attached with no Barlow lens and with my basic 6mm telescope eyepiece. I then connected the camera. (I was happy to see that my t-ring adapter DOES accept a
  7. vlaiv, I also used your calculator site. I used my Canon 1000D camera with the measurements you provided. I did it both with a Barlow lens added to the configuration and without a Barlow lens in the image below. Thanks!!
  8. Cornelius Varley. If that's the case, with my sensor the moon would roughly fill 1/3 horizontally and 1/2 vertically. (7/22 and 7/15) Thanks! Ouroboros, I used your lunar picture from above, made the moon 117% larger to accommodate for my 700mm telescope instead of your 600mm. I saved it in grey scale to show the moon as it will look normally. Then I resized it to the 3888 pixel width of my sensor. The image I attached below should be as near as possible to what I will see I guess. Nice!! Thanks again guys!
  9. Cool! Thanks vlaiv and ouroboros! That really helps! So vlaiv, at 1070 pixels, the moon will fill 41% of my image vertically and 28% of my image horizontally. That really clears things up in extreme detail. Thanks a lot!! Thanks for providing your picture of the moon ouroboros. That also really clears it up. I appreciate the info guys! Thanks!
  10. Good point Stu! Thanks guys! I REALLY appreciate the assistance. I guess this is a new language to me at this point. It's a bit overwhelming at this point. The good news is that I'm a quick learner. When I got a DSLR, all the language was new and overly complicated compared to point and shoots I'd used previously (aperture, ISO, shutter priority, lens zoom measured in millimeters, f-stops, f3.5 vs f22, field of view, EF-S vs EF lens mounts, crop sensors vs full frame, STM, white balance, exposure, polarizers, etc...) That stuff all makes sense to me now. Ouroboros, I have
  11. Thanks Luna-Tic! That helps a lot!! I guess the "proper" semantics for what I was trying to ask in the first place is, how large will the image of the moon look in my pictures compared to how large it looks at 18mm and at 55mm with my camera's kit lens. OR How large will the image look compared to how it looks on my 50mm lens. My camera has a crop sensor. If I'm not mistaken isn't a 50mm lens pretty close to what the naked eye sees? If I hold my camera to my right eye with a 50mm lens isn't that pretty close to what I'd see in size if I looked at the image directly with my lef
  12. eye roll..... OK, thanks for the "CLARIFICATION"!! LOL!! Clear as mud now! ha-ha! The telescope without an eyepiece lens surely will make the image look larger than if I was standing next to the telescope with my naked eye. YES??? And it will surely make the image on my camera's sensor look larger than if I just took a picture with my camera and a basic 35mm lens for example. YES??? I am just trying to figure out (roughly) how much magnification hooking a DSLR up to a telescope in prime mode will get me, compared to say, using a 35mm lens or a 50mm lens or an 18mm
  13. Hi everyone! I am new to astrophotography so please pardon me if my inquiry is a novice question. I have a Canon EOS DSLR camera. I also have a Galileo brand 700x76mm reflector telescope with 1.25" eyepiece. I just ordered a T-mount for Canon DSLRs and a t-ring 1.25" adapter to slide into my telescope. (from B&H) Those adapter parts will arrive later this week. I will be viewing it in the prime configuration where I will use no eyepiece lens. I may or may not need a Barlow lens in this configuration. (I have been told it depends upon the telescope, whether or not you need a Bar
