FINALLY got the hang of the DSI

[ballaratdragons]

HOORAYYYY!!! :cool: :party: :jump2:

Thanks to Karls help, I have finaly got the DSI taking images!

It was a rough start but by the 3rd image I got it happening :)

The 1st image - 47Tuc- was a disaster :lol:
The 2nd image - Tarantula - I knew I was onto something :thumbsup:
The 3rd image - M42 Orion Neb- I am really getting the hang of this. :)

M42: 12 darks, 65 lights, processed in Photoshop at different levels, then taken over to easyHDR.

I'm getting there ;)

'on ya buddy! :thumbsup:

Just goes to show, you can't keep a good man down.

Looking forward to your signature great shots!

[davidpretorius]

top stuff Ken,

really pleasing to see you off and running

[avandonk]

Thats great Ken. I am sure the images will keep on improving until you have wrung as much out of the DSI as you did the old Tocam.

G'Day all,
Well done Ken! Hope to see you give it a real work-out like the old Toucam.
Looking forward to them all.
Cheers,
Duncan:thumbsup:

Thanks all!

The encouragement I recieved along the way is certainly paying off.

I'd still be doing cave paintings of stars if Karl hadn't been so patient and helpful. Thanks heaps Karl :thumbsup:

Forecast is for cloud and rain for a while, so I hope I don't forget how to do it by the time it clears up again :lol:

LOOK OUT SKY . . . HERE I COME :cool:

Well done K K Ken.:D
Don't forget, Gain & Offset are the key to using these camera's.
Looking fwd to some great images.

[ballaratdragons]

Deano, I haven't worked out the Gain & Offset yet. I'm still a bit puzzled by that section.

All my imaging for the last few years has taught me that Zero Gain is the go. But with this DSI it seems the higher the better :shrug:

And what on Earth is 'Offset'? I've never heard of it before.

[DeanoNZL]

Hi Ken,
This is what I could find out about Gain & Offset from the net

The Gain and Offset controls work together and effect the camera output signal. The Gain control effects how much CCD gain is used by the electronics during the A/D conversion process (drives the display right, brighter). The Offset control adds an offset to each pixel so that no pixel has a zero value anywhere (lost data) and drives the display left (darker). For short exposures, under a minute or so an offset of 50 works fine. As you increase the exposure or have brighter objects you must decrease the offset so that the signal does not saturate (drives the histogram to the right and all you see is a white screen). You can adjust the offset values during the preview phase for correct value. For 3 min exposures I use about 40 offset. for 8 min about 15 offset. As long as the histogram display does not exceed 65K on the right or 0 on the left, you are the normal operating range of the camera electronics and it will not effect the image quality

I try to get a histogram with a small space to the left, not hitting the roof, and trailing off to the right.
I am still a newbie at this, but thirsty for knowledge, if there is anyone else who can cast more light on this, I would appreciate this.
Hope it helps
