2nd night at DSI gone wrong!

[ballaratdragons]

I have just spent my 2nd night at the DSI and nothing is going right still!!!! :mad2:

Rather than muck around with Meades Invisage, I used MaximDL for the first time. I had MaximDL open on one screen and the tutorial open on the other.

I followed every step to the letter through the whole tutorial and yet it still went crazy. The images on-screen were monochrome, so I thought "no big deal, it will turn colour in the end". It didn't.

It was suppose to stack the images and subtract the darks I took. It didn't.

I took the single images into Registax and it showed up a wierd cross-hatch pattern!!! That's the same wierd effect I got in Invisage!

How can it all go so wrong when I followed the Tutorial exactly???? :shrug:

Any help much appreciated :prey:

These are supposed to be COLOUR images!

Hi Ken,
The images from my Orion Starshoot look exactly the same until I (de-mosaic) convert to colour.
Not sure where the commands are for this are in the Meade or Maxim software.
Hope this helps.

Look for "DeBayer" or "DeMosaic" in the options.

In Registax, you turn on colour, and in the options tabs on the main alignment tab, you turn on DeBayer, and select one of the 4 patterns. Unfortunately, I don't actually know the correct pattern for the DSI. You can try them all and check which one "looks" right until you find out the correct one to use.

Thanks for the replies Dean and Turbo.

Yep, I 'DeBayered' and 'DeMosaiced'. That was in the tutorial I followed. Wierd how it still did it.

Also, there was no control to 'convert to colour'. :shrug:
Unless they don't mention it in the tutorial, but I didn't see one anywhere either.

Your not having to much luck with this DSI Ken, I feel for you as I know how much you loved imaging with your Toucam, trade her in mate, and get what you know you can get results with. :whistle:

Leon :thumbsup:

After reading through the tutorial again, I have discovered one of the Myriad of mistakes I must have made.

Bad pixel removal should only be performed after color conversion; otherwise the Bayer matrix will be filtered out resulting in a loss of color.

If I remember rightly, I think I removed bad pixels 'before' I 'DeBayered'.

I still can't find why it didn't stack or subtract the darks.

Ken are you sure that you didn't buy the dsi pro monogrome cam ?:rofl:
Just joking.
When you are in envisage try it first with the simple settings and see how it goes.
This way you will get at least an color image (i hope).

For "one-shot" color cameras, such as DSLRs, Meade DSI, etc., the color information is built into the raw frame. The images should first be calibrated. If flat-fields are used, turn on the "Apply boxcar filter" option to remove the Bayer matrix; otherwise the color balance will be affected by the color temperature of the flat-field light source. Next use either the Convert CMY (http://www.iceinspace.com.au/forum/Context2/HID_COLOR_CONVERTMX5.htm) or Convert RGB (http://www.iceinspace.com.au/forum/Context2/Convert_RGB.htm) command as appropriate. DSLR cameras require the Convert RGB command; other cameras such as the DSI require Convert CMY.




Is that what your looking for Ken

[ballaratdragons]

Yeah, kind of, Shawn.

I don't do any 'Flats' or 'Biases'. Just 'Darks'. The tutorial tells me I can succesfully just subtract the darks from the lights without worrying myself with Bias or Flats (no need to calibrate). I did it their way and nothing happened.

Martin, I don't like Envisage. Besides being a needlessly over-complicated program, it crashes whenever it feels like crashing.

I find MaximDL much simpler (the commands layout is easier to use) and it doesn't crash. It also fits on my 800x600 res laptop. Envisage doesn't.

[ballaratdragons]

Nah, the camera isn't at fault. It's the operator :lol:

Dang fangled computer programs :tasdevil:
What makes it harder for me than for others is I don't even understand the lingo in the tutorials . 'Computer speak' leaves me lost.

[ballaratdragons]

Here ya go, problem solved!

I'll just add my own colours :lol:

Pretty ain't it :P

[mill]

Aaaaaahhh!!!! nice water colors :P

Hi Ken, I have a go on imagining with DSI Pro last night. I’m not impressed with sensitivity of this camera. GStar beats it hand down. Can you get “live preview” window when you use DSI with Maxim DL? With other cameras I can see image live on the screen but with DSI I see only the images I have exposed. Tried DSI as auto guider, no go, could not connect to COM port.

[ballaratdragons]

No Karl, no live image with DSI. The closest is in 'Focus' mode which updates every 1 second (or more).
