  1. I recently posted a picture of B33 using my Optolong L-Enhance filter which was not too bad, a bit red, for my first time trying out Pixinsight. Last night I managed to get nearly 2 hours using my IDAS D2 LPS filter and after watching many Youtube videos I've managed to get the following using my Esprit 100ED and modded canon 450D, 21*300s Lights, flats, darks and bias frames. I think I'm starting to get my head around post processing.
  2. I've just fitted a 2" IDAS-D2 filter into the William Optics Flat61a flattener following on-line instructions. It strikes me as odd that the filter is installed with the front of the filter facing the camera sensor rather than the 'sky', I'm assuming this is correct and shouldn't cause any reflection issues? For info, I've attached a couple of daylight images of the filter in 'action' on a colour calibration chart showing the natural colour cast The image above, without the filter fitted, is colour profiled in LR and white balanced using the middle grey colour patch The image above, with the filter fitted, uses the colour profile of the first image and the white balance is also from the first image The last image below was colour balanced using the middle grey colour patch in LR and clearly failed lol Assessing the grey colour patch there is no red in it at all so obviously the calibration would fail. It will be interesting to see it working under normal conditions photographing the night sky
