Info for Those considering upgrading Luminera Came

Posted By Oliver Pettenpaul

Hi Jim,

sorry to hear that.
The USB2 interface and almost proprietary software solution is what I don't like at all regarding the fine Lumenera cams. I prefer IEEE1394a/b (aka firewire) solutions supported by a wide range of protocol stacks, commercial and free software (e.g. Coriander for Linux). I found an industrial machine vision camera with 1394a interface comparable to a LU75M at a reasonable price - a detailed review and test will follow. Other cams with various CCDs are also available, the version with an ICX285AL should make one hell of a lunar and planetary cam.

Best regards & clear skies,
Oliver

Anyone using Toucam NO-RAW mod?

Posted By Oliver Pettenpaul

Hi John,

I can also second Ed. I use my color ToUcam only in optimized non-raw mode for the last years. The raw mode produces even better results but the hassle of additional processing efforts and the restriction to 5fps only pays off in excellent seeing.

Best regards & clear skies,
Oliver

Edit: I meant optimized non-raw above, just changed it...

Hi Richard,

amazing details in your image 8O grin Thanks for sharing!
I just recovered from a bad cold, have my new cam ready to go and the waether forecast for the next nights looks cloudless - I can't wait to image mars myself again smile

Groetjes & clear skies!

Question on multiple alignment

Posted By Oliver Pettenpaul

Hi Luca,

yes, you can do multiple alignment processing in Registax but it's a manual approach. Simply process the source material several times and use different key features in the image as an alignment point. Make sure you apply exactly the same processing parameters for every run.
I use Photoshop to combine the results: Paste the resulting images to individual layers and align the layers (~300% upsampling makes aligning easier). Then I apply a layer mask for all the different regions I want to have in the final image (the areas around the alignment points) with a littler "feather". As Paolo already said this is very time consuming but quite effective, especially for captures from suboptimal seeing conditions.
Has IRIS features to automate multiple alignment a bit ? This would be quite nice smile

Best regards & clear skies,
Oliver
