You can turn both calibration options off by making sure that under Stacking Parameters->Intermediate Files->'create a calibrated file for each light frame' and 'create a calibrated file for each light frame' is unchecked;gboulton wrote:I don't really understand this statement...since this has never been an issue before, and it's not like DSS gives you a choice. You can either do Per Channel or RGB calibration...there's no "Don't do any" option. ONE of those two types of calibration has been done to every DSS image StarTools has ever processed.admin wrote: Ok... any sort of calibration in DSS will also significantly affect how much detail can be extracted, how well noise levels can be determined and typically causes clipping and bloating of stars (as is quite apparent here).
So you can switch from this; To this; The following is a checklist for DSS, which should (should! - I'd love to verify this with some data) yield the best results in your situation;
- Make sure that under Stacking Parameters->Intermediate Files->'create a calibrated file for each light frame' and 'create a calibrated file for each light frame' is unchecked.
- Make sure that under Settings...->Raw/FITS DDP Settings...->RAW Files tab->Color adjustments->Brightness, Red scale and Blue scale are set to 1.0
- Make sure that under Settings...->Raw/FITS DDP Settings...->RAW Files tab->White Balance->Non of the options are ticked
- For best results from a DSLR when not dithering and when few frames are available, under Settings...->Raw/FITS DDP Settings...->RAW Files tab->Bayer Matrix Tranfromation->Create super-pixels from the raw matrix
It'd be so awesome if you could still retrieve that data - I'd like to write up some instructions for people using DSS, as getting the right, absolutely 'virgin' data has become more and more important and there are a number of pitfalls on the road to getting there!Bugger Would've liked to learn why the data looks like it does. Storage is so ridiculously cheap these days though!
It's not storage cost..it's OCD
As it happens, however, it occurs to me that i may not have purged them from the session laptop yet however...I frequently copy rather than move them over the network (on the off chance something bombs during the transfer) and sometimes don't go back and delete them from the lappy...I'll check next time I think about it and let you know.
