Took this last night of the beautiful Centaurus A Galaxy. I removed the IR Filter from the DSI. I think it made a difference. Will be posting another pic of it with the IR Filter so can compare the differences.
12 x 1 minute 24 sec exposures stacked. Out of all my pics, I think this is one of my best or even my best! Can actually see the entire black cloud splitting in the middle. Love my DSI!
processing & technique wise, I would say yes. I try and still look at the stars first to check for star trails etc and then the main object.
Another rippa.
Hows the star tests going. I am asking only just to see if you can now start to push the dsi to its absolute limit. If you can keep tweeking polar alignment and make sure that collimation is as near perfect, it would be great to see diffraction patterns and really tight stars that tornado and the other dso gurus get.
Take nothing away from what you have accomplished, now is the time for that final finish to make these wall posters.
Like Asimov and his refractor, he squeezes the absolute best out of that, through making sure everything in his control is spot on.
So I would love to know if the DSI is sensitive enough / good enough to produce tight stars / diffraction patterns and hence top class images. And the only way that can happen is great collimation and great alignment etc etc

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.
hey mate, one more favour, make sure the star, not quite as bright as sirius, centre it right in the middle of the field of view and defocus a small way out and take a few short intervals images. then defocus inwards and then take a few images.
ideally that sirius shoud be round, not flairing from say 7 oclock to 12 oclock.
just would like to confirm the collimation against the laser
Great shot there. The DSI really lends itself to taking good pics of objects like this, as they well suit thr chip size.
The IR filter will make more difference with red emission nebulae like the Horsehead, no filter will allow in more nebula light.
Heres a challenging one for you, Planetary neb He2-111, its deep red so remove the IR filter for it
Heres large and small scale finder sharts for it generated with Star Atlas Pro. The nebula is easy to photograph but VERY hard to see. It took Andrew Murrels "Hector" 20 inch Dob at Lostock to see it.

Will give it ago tonight at it Scott thanks for keeping me busy at night
Love my DSI!
, got my respect mate.
