    Default Ethos for my CPC1100



    Okay guys I have money burning a hole in my pocket and im trying to decide which ethos eyepiec to buy that will give me the biggest, clearest view of saturn. I have a 50 dollar 10mm eyepiece right now that gives me great views everynight at 280 x mag. So I really want to Max out my cpc1100 and see how big I can go. I do not know anyone who owns an ethos eyepiece with a setup like mine so I have come to you guys.

    It's not a fast scope, so you will get decent quality from budget eyepieces. And your 10mm is probably about as much magnification as it will take under normal conditions.

    If I had money burning a hole in my pocket, I'd be looking for an awesome wide-angle eyepiece, or an observing chair, or something else. In fact, you can just send me a cheque and that will solve the problem!

    I have a Cgem 1100 which is the has the same tube. I have a 6mm Orion Expanse ep, it gives me 467x. It does a pretty good job. I have put my 2x shorty barlow on it and that becomes to much power. I am sure an Ethos in the 6mm range will work. Most of the guys on this forum say it is to much. They are probably for the most part right. I like to push the envelope and always see how far I can go. However being that I have been able to use my 6mm everytime I tried, every night will be different. Your eyes might be different then mine as well and 6mm may be to much for you. Like KiethBC said our slower scopes, will work fine with lesser priced ep's. I have a 17mm baader hyperion, which has become a quick favorite of mine. I am considering a shorter one perhaps a 5mm. I would even consider a 3.5mm just because I have a 10in dob. It probably wouldn't work on my 11in sct.

    I guess try something along the line of 6mm if you want but make sure you get it from a place that will let you exchange it, if it is not working for you. Another consideration would also be to get a 15-20mm and a good barlow. Anyways good luck, our 11in tubes really can unlock the night sky if we want them to.

    As said above, I'd go for something lower powered than your max and barlow if need be. Ethos eps are so expensive, I'd hate to only use every now and then.

    Gwozhog:

    I run a CPC1100 in my observatory... BUT i seriously have to question why you want to buy an ultra wide angle eyepiece to view a small target like Saturn...All that is going to do is make Saturn "appear" small in your total FOV... its actual size will be the same under equal magnification ..BUT you will see a heck of a lot of open empty space around the planet...

    For Planets I normally use a Pentax XW (10 mm) or on Fantastic nights use a 8.5 mm Pentax XF. (68 degree FOV @ 280x or a 60 degree FOV at 329x).

    Now if you wanted to buy a low powered wide FOV eyepiece to gibe you a huge FOV to be used on DSO's especially open clusters etc then the Ethos may be what you need...

    BTW... I run mostly Pentax XW's for high powered views and Panoptics for low powered views (I find 68-70 degree FOV more comfortable to use) BUT a few years ago I won an Orion Stratus 17 mm eyepiece as a door prize and it works so well in my CPC that IF I were buying eyepieces today I sure would rather buy THREE of them)then I would ONE of the Panoptics or Pentaxes.......

    CLEAR SKIES....

    So I was at the George Observatory a few weeks ago and I brought my scope out there. There was a guy next to me and I heard him talking to his buddy about his new 10mm Ethos. I walked over and said hello and we compared the ethos in his 12 inch dob and my cpc1100. I can honestly say for the money I was not to impressed. I thought it worked alot better in his dob than my scope.
