ggreene1 Posted May 15, 2012 Share Posted May 15, 2012 Here are a couple pictures from my first attempt at Solar imaging. Trying to prepare for the transit of Venus in June. Also there will be a partial Solar eclipse here in the US this Sunday. I'll be sure to post a link to some pictures. Here is the link to my first images using my Baader filter that I just built. These were taken with my Canon EOS 40D, my 8" Celestron SCT and my Baader solar filter.Not too bad for a first attempt.http://gordongreene.com/photogallery/displayimage.php?album=77&pid=3041#top_display_media Link to comment Share on other sites More sharing options...
ggreene1 Posted May 15, 2012 Author Share Posted May 15, 2012 I have another question that maybe someone can answer. I would like to use my camera, but get a smaller image when viewing the Sun. Is this possible ? I have a Canon EOS 40D camera, an 8" Celestron SCT. I'm using a Canon T-ring and an 1 1/4" Barlow T adaptor (that's what the box says) Any thoughts would be appreciated.

mike.brightmore Posted May 16, 2012 Share Posted May 16, 2012 I took this image today using a Canon EOS (Rebel) 350D on a 4 inch refractor. To get a similar image size with your SCT you will need a focal reducer (not the Barlow). Link to comment Share on other sites More sharing options...
ggreene1 Posted May 17, 2012 Author Share Posted May 17, 2012 Mike, does it still allow the camera to focus correctly (apparently it does judging by your image) I don't want to have to buy a bunch of new part. Trying not to spend too much money. Does it thread directly to the OTA and to the T-Ring that clips onto the camera body ??? Thanks for the help.

mike.brightmore Posted May 17, 2012 Share Posted May 17, 2012 The Celestron focal reducer screws directly onto the back of the scope. The visual back then screws onto the focal reducer - then diagonal and eyepiece (or camera T-ring) as normal. You will have to check exactly which reducer you need for your scope and image size you want. They are also useful for reducing magnification and increasing the field of view when looking at many of the deep sky objects visually. Here is a link to the Celestron focal reducer ... http://www.firstlightoptics.com/reducersflatteners/celestron-f63-focal-reducer.htmlThere are other makes and sizes. I have not had any problem with focus using a variety of reducers and cameras. Link to comment Share on other sites More sharing options...
ggreene1 Posted May 17, 2012 Author Share Posted May 17, 2012 Thanks Mike, I actually purchased one yesterday for $115 from a company called Adorama here in the US. They offer free shipping on almost everything. The one you linked is the one I bought. I figured since the Venus transit doesn't happen everyday and I really want some good pictures of it, I would buy it. Thanks for your input.
