Quote:i would like to buy a CPC 1100 HD Edge for my visual observing of deepsky objects and planets.I will use the CPC most of the time from my light polluted sky (limit magnitude 4 / 4.5) and about once a month from dark sky (l. m. 6 / 6.5).I have a lot of experiece with a 10" dobson GSO under that sky so i know what to expect from this kind of aperture.My question is: the CPC 11" how will perform when compared to the 10" dobson on deep sky observing ?I did alredy some math, if i include the greater obstruction of the Celestron C11 and the light loss from the extra glass in the optical path i can conclude this:1. both have the same light trasmission2. both have the same theoretical contrast (D-d)3. the C11 have a bit more of resolutionSo both should perform more or less equal.Now, these are theoretical assumptions, im looking for some real life experience under sky, maybe someone of you have compared these telescopes.
