I'm cobbling together a 24" build and have reached the stage where I have to cut out some of my front rocker board to accommodate the lower struts at an almost horizontal angle. I was considering it this afternoon with the struts hard down against the front rocker board, and thinking - hang on ... I never observe that low with my 16". Why would I bother with a 24? I've been around the block at this point and tried to nab the stuff down low north like notherners have done the same down south. OK, so maybe you do it on a whim and on the odd occasion ... but really ... the experienced observers know not to bother looking through pea soup. It's easier to jump on a plane and fly up (down?!) to an accommodating reflector owner in a better location.
So my question is this: at what latitude do you pull the pin for observing? And I'm not talking the bragging rights stuff where you saw something famous, but the working observing area where you hit the point of diminishing gains?
I have pretty clear skies where I am ... but geez ... not sure if I would bother at an attitude that warrant cuts in this rocker board at this point in my observing career.
