EP projection is where you leave your normal viewing eyepiece in the telescope & whack the camera up against it. To get different magnifications, change eyepieces.
The moon shot using: 15mm EP
Jupiter: 5mm
Saturn: 5mm
Mars: 5mm with barlow lens screwed directly to the EP giving existing eyepiece magnification X 1.5
Orion nebula: 35mm All at full zoom except orion. Not much chop doing faint DSOs unless you want to stand there & fire off a couple of hundred shots using the 10 sec delay on the camera....I can get one, 2 sec shot every 14 seconds. If you use 4 seconds, you'll get heaps of noise in the final stacked shot making it just about worthless. I recommend just sticking to planets/moon & bright DSOs.....Good for bright star clusters & globulars too.
It's hard work with this camera just trying to work out all the settings for each given object. The camera over-exposes bright planets cos' of the dark sky background. I have to use different size aperture masks for different planets....depending on what scope & what magnification. It's great fun though & if your up to a challenge by all means, give it a shot!
When your ready to have a go, give us a yell & I'll try talking U threw some of it.
Thanks for your comments.
BTW I'm all set up ready for another bash at mars, just waiting for it to rise to it's max elevation.
Using the 6" F8 achro refractor stopped down to 3.75"/5mm EP with contrast booster on. Camera set to AVI.....Then it's 4-5 hrs processing all the videos!!
