Thanks Davo. Credits to you also for helping me out with Registax and your online tut is awesome! Don't think I can get as far as now without your help. Remember my shocking jupiter avi i sent you? lol . Everytime i image, even though I have marked my tripod, i always check polar alignment directly pointed to the octan's region. On my polar scope, it actually has the octals region in it to match the exact stars as well as rechecking collimation with the laser. I'm really fuzzy!
With stars diffraction, i don't think the DSI is capable with faint stars. Have attached sirius which works but faint one's no.
Thanks Ving and Mike for your kind words
lol not master yet as i have seen better pics from other people such as Matt Taylor and Chuck with the DSI. Don't get why people think the DSI is a toy. For $500, is an excellent device to capture DSO's. You can take the same quality pics as a DSLR if you master the DSI.
Anyway, have also attached one with the IR Filter. Can't see that much of a difference. I think without the IR Filter is slightly more details.
