I was interested to see how the QHY8 compared to the QSI on M17 - one of this months challenges. So here it is
* Scope: (+/- reducers/flatteners) 10"SCT with f6.3 reducer
* Imaging device: QHY8 OSC camera
* Mount: Hypertuned EQ6 Pro
* Guiding: PhDguiding using DSI II Pro
* Exposure details: (include ISO for DSLRs, temp for CCDs) 24x5min
* Stacking method: (Median, average, sigma, etc. Darks, flats &/or bias frames) No darks, but flats -bias-flat darks stacked in DSS (medium combine)
* Summary of post processing: Levels and curves in PS3 and slight sharpening
* Darkness of imaging site: (Good, bad, ugly!) Really ugly light pollution from BrisVegas 4.5 Km away plus a neighbour's searchlight pouring into the backyard. Thank heavens for the observatory
* Date(s) image taken: (Ideally the image will be taken during this month, but previous work is not excluded to allow for weather and other life commitments) Taken on Sunday 7 June 2010.
