Tak AP QSI Canon
Quote:I agree on the oag suggestion. It will make all potential guiding issues go away. I would use it on any focal length scope because its easy and it works. I suggest the qsi583wsg. It's an awesome camera and it has the low read noise that you need for narrowband. It also comes in an elegant package with integrated filter wheel and oag. Not cheap but. Worth the investment in my opinion. You won't have to deal with clunky filter wheels and separate oag's.
Quote: would also prefer to do AP with smaller refractors and camera. I have an EQ6 with EQ Mod. I also have an orion guider a short tube 80, an 80mm WO ED and a R200ss. I do also have a Cannon EOS lens adapter and like the idea of small wide field lenses.To the mount, the EQ6 is pretty heavy, I do see iOptron has some new mounts, that appear lighter, but not sure if they are any good

Quote:Buy a good mount, plan on it being the highest cost item.Buy a good APO refractor, figure it to be 2nd highestBuy a good camera and filter wheel AND good filters. It will all cost about what the telescope did.Finally, get a good small 50-60mm Borg Mini refractor and a nice guide camera. Then buy MaximDL and CCDStack and of course Photoshop CS5 or later. Now spend hundreds of hours learning how to get it all right. :^)Simple, right?Blueman
