Thanks Mike. Yes, as I explained in the info, the data is upscaled. The full frame is only 1024x1024 pixels (Apogee U42 2x2 bin), hence lacks a little resolution. Though the data was good enough to scale and hold reasonable resolution. A 1x1 would be a real kicker. Indeed the 24" is great bit of gear, but more importantly is the location where its installed can support it - dark skies, excellent seeing, thus you can get some lovely resolution from the instrument. I think you've asked me about costs before relating remote imaging. Its difficult to put a figure on it - this image was a specific collaboration activity between Alvin and I. The Lightbuckets "easy imaging" facility gives some excellent value for money...even if you simply acquire some high resolution luminance to match it to some low res RGB you've previously taken. At 4876mm, the Helix fills the frame of the U42 so not much can be done on the window effect. I've attached a reduced size full frame for reference. Thanks again for your comments.
