Cannot sleep .... 12:30am Still 28C outside and 30C inside!. 35 days over 30C - a new record for Brisbane. Cloud and rain nearly every night. At least we didn't get the floods like further North. Anyhow ... Just lurking on CN forum and seen a blokes thread doing EAA on a 10" push to DOB (yes push to) and a RT385 camera with 0.5 reducer. He has a few links in the thread to some of his live videos which really let you see the technique. He sets 2 sec very high gain to "find" the object by pushing the scope around. Then drops exp time until stars are still round - ie 1 second or less (!!!!), then lets the stacking in SC take care of 70+ sub second frames, or until the object disappears out of the FOV! Ie as it "floats" through the FOV. End result is quite a few galaxies and all the usual bright nebs .... EAA on a super cheap budget with super quick mount setup! A very interesting technique which I'd love to show my old mates in the astro club. Maybe the weather and the ol stuffed back will let me get out there sometime!

Yep, when I first started doing Video about 15 years ago I used a ToUcam webcam in my 12 inch f5 Dob. It's all I had. Visitors to our club got to see Orion Nebula and star clusters in a matter of seconds! Blew them away!! Also just recently, I inserted my ToupCam IMX224 into a fellow club members 16" Dob and we checked out the planets and Moon and a quick look at M42. In his 16 inch Dob I had to use a Negative adaptor so the 224 could reach focus. It had to be used without a focal reducer. I never stacked any frames. All DSO views were just near-live rolling frames and the Solar System objects were all live video. Was fun at the time

The technique is very interesting and as a start it is very good.
The problem is that we all want more and every time we try to improve the quality of our work. We are not satisfied with blurry images and without detail, we put engines, Goto, we want smaller objects, bigger nebulae, etc ...
On this topic I opened a thread in another place of the Forum so that people could make simple and cheap proposals to cover all heavenly expectations and help those who are just starting

I did a post about them here Howie -----> LINK You can use a Focal Reducer with the Negative adaptor. Except the focal reducer I was using a few weeks ago with the members 16". It was one of those silly ones with the stopper ring around it so you can't insert it deep into a focusr. Stupid design.
