Quote: So if I understand well short exposures help to bypass the 8/3 and cogging issues..and thats a way to come around the problem but I believe though that they can't substitute always longer exposures.
What if someone needs to go deeper on the picture and capture fainter objects that need exposures of at least 10 minutes...or for making it simple...what if someone has to do exposures of 20 or 30 minutes because uses Halpha;,O3 and S2 filters? Both issues inevitably will be present ( unless fixed) in every single exposure as I understand that the period of the Cgem Is less than 600 seconds..and ...if not ruined , every sub will be influenced in a way..:(...specially at longer focal lengths...
Quote:i am curious as to (1) the keeper rate; (2) the focal length; (3) are you using a refractor or SCT; (4) are you using OAG - for Jason B.'s claim of "10 to 15 minutes all the time with a CGEM."
Quote:3-5 minutes of autoguided shot is barely an achievement for any equatorial mount even a cg5 or a neq3.
Quote:Everyone would go with 1 or 2 second shots..thousands of them so the noise would be so low they would not even need to pass any denoise filter or even bother to shoot darks.
Quote:The DX is $1699 on amazon & best buy, that's $500 cheaper than it was last week and $500 cheaper than the Atlas...One question I do have is, WHERE DO YOU GUYS get your gear? Who is the best with customer service and help when there is an issue?
