Hi Shah,
You wait to see the live colour views with your Mallincam and your 18 incher compared to your 8 incher. I use my Mallincam hyper colour with a meade 12 inch 200R and the images are just mind blowing, so with over double the light grasp of the 12 incher the 18 incher should get Hickson 50 group of mag 19 - 20 ish galaxies at 56 seconds
no problems. M51 will burn out your screen at 56 seconds using the 18 incher
,Lookout cosmos here you come. Great idea with the servo-cat so you can use your video systems. Do you post on the Yahoo tech mallincam forums? make sure when you get it all up and running you post the results on the Mallincam forum. Have fun.
Matt.
