Correct Image Star Diagonal- need opinion

[toothferry]

I'm thinking of buying a 127mm mak and an accessory correct image star diagonal for use with it, plus would like to be able to use that in other refractors as well. <br /><br />I see two for the same price on telescope.com<br /><br />07216 1.25" 45° Correct-Image Diagonal <br />08787 1.25" Correct-Image Star Diagonal <br /><br />7216 requires 5/8" more focus travel, the webpage says. otherwise, is there a benefit to getting the 8787 model? I want the one that has the superior optics <img src="/images/icons/rolleyes.gif" /> but also want one that is compatible with most any refractor or mak that Id like to use with it.<br /><br />can anyone help me out with expert opinions? thanks very much!

Only use for a correct image diagonal is terrestrial viewing, it's not used in astronomy. (well hardly ever anyway) With a 125 mak the image will be reversed left/right but it will be right side up anyway, same with a refractor. (OK if you use a diagonal) Straight through a reflector is reversed left/right and upside down. Reflectors views are upside down and it never bothers anyone.<br /><br />Even number of mirrors upside down, (0 or 2) odd number of mirrors right side up. (1 or 3) A mak has 3 mirrors.

Thanks for answering my post! I believe I will be using it as a spotting scope too. It going to come with a equatorial mount, but I'd like to use it on a sturdy camera tripod or alt-az mount during the day, on vacation. I wonder if any type of extra mounting bracket would be required. BTW, here is the mak I'm thinking about purchasing<br /><br />http://www.telescope.com/shopping/product/detailmain.jsp?itemID=149146&itemType=PRODUCT&iMainCat=4&iSubCat=10&iProductID=149146<br /><br />and below is the other tripod I'd like to be able to attach it to during the daytime: (does it need a bracket?)<br />http://www.telescope.com/shopping/product/detailmain.jsp?itemID=290&itemType=PRODUCT&iMainCat=6&iSubCat=24&iProductID=290<br /><br />or would one of these camera tripod be better, and would I need a braket for it?<br /><br />http://www.telescope.com/shopping/product/detailmain.jsp?itemID=78&itemType=PRODUCT&iMainCat=6&iSubCat=24&iProductID=78<br />

I think all 125 mak's are useless, more so if made by Orion (Synta). The only product Orion (Synta) has worth the money are their dobs.<br /><br />Save more money and get an 8" SCT (either the Meade or the Celestron) after all you are talking about investing almost $1000 in a scope/mount and an extra mount. What you are looking at isn't even motor driven.<br /> <div class="Discussion_UserSignature"> <font size="1" color="#3366ff">www.siriuslookers.org</font> </div>

<img src="/images/icons/smile.gif" /> I've got the XT10 already <img src="/images/icons/smile.gif" /> <br /><br />..believe I will just get a spotting scope for carrying along with me on vacation. It's difficult to find the right attachments for those maks.
