Here's my second attempt withe the ASI120mm with RGB filter from Baader, I tried using the RRGB as suggested by THEO here on SGL for the extra luminance and I do think it's brought out a bit more detail. I know this has been contended before but what's the opinion on the Televue 2.5 powermate as opposed to the Revelation one I using?. Thanks Campbell
Here's my first attempt at a wide field from last night, this cygnus taken on an unmodded canon 550d with a Sigma 30mm 1.4 lens, mounted on an EQ5 pro and guided with a finder guider with a QHY5v. Consists of 12 x 180s @ f2.8 & iso400, stacked in Nebulosity and finished in CS6. There's a fair bit of coma in the top left so any tips on development would be appreciated. Thanks
Here's an image that i just finished processing after finding the lights that were taken months ago on a memory stick that i was emptying and had forgotten about, only had the lights so took some darks this morning by using the chip temp shown in images taken via Backyard Eos. I reckon there's 19˚c between ambient and full speed on my 550d so put it in the workshop with the heating off and seemed to match them well. Needs some more data and my processing is all that but I'm quite happy with it for a surprise find. This image was taken with a Skywatcher 200p, Heq5 Guided via PHD Canon 55D unmodded, Backyard Eos 24 x 180s Lights @ 1600iso 19 x 180s Darks only (taken months later by matching chip temp) Processed in Nebulosity, CS6
