I get so much of my astro applied gear from Bunnings☺.
We need a section in the photography section for clouds...probably get more contributions there than the rest combined☺.

You even put the scope upside down in typical Down Under style

You REALLY need a Starlight Xpress camera for that profile, or a ZWO.

one day i will have a real camera - one that takes photons

i am happy to use the 450D for the minute but i need to explore what options there are to make the most of real estate and the need, the need for speed

for SPSP i will be on a battery, but for Astrofest it will be different, so could run a amp sucking cooled megacamera. one shot is the way i will stay for the minute

I have already been blamed for our sudden weather change here after my very recent order. Good luck with the scope Dave. I like others think once you get a smaller profile camera you will be happy as can be.

Dave the 1600 is about 1.27" per pixel but has 1.2e read noise. The 71 on the other hand is about 1.6" per pixel and has 2.3e read noise. I still think the 1600 is good. Either is probably a nice camera.

Here is an interesting read. A Celestron white paper on the RASA. It deals with concept, design, use, cameras, stuff and some of the things discussed here. Reading it I found the answer to something I was curious about - the size of the central obstruction /obscuration. (114mm in diameter)

Best

thanks Paul, was looking at real estate but i can see your point but its only 12bit where the other is 14bit. arrggg this is where it gets hard what do you trade off? the other is well depth, the 1600 is 20k where the other one is 48.6k
