Description

Rev A&B: HA Processed

Rec C: OIII unprocessed (calibrated only) stf +htt only

Rev D: SII unprocessed (calibrated only) stf+htt only

Rev E: NII now added 5x1800 only (can't seem to add to acquisition details)

For those wanting to see the filter by filter performance I have added the raw stacked images for other channels. Consider these have been taken under average UK skies - so I am very happy with these results. I have taken what I would consider to be an average number of subs for 5nm in OIII and Sii and the results to appear to have improved SnR. No basis for this other than visual inspection.

Hope this helps someone out there

Nii comments - well appears there is a lot of data - this is the raw stretched data with no processing and just 5 subs for the test. This data will reinforce that which is missing from the soft HA image (656.3 range) and I think and will subject to blending reinforce the other channels. Its a lot of data however you look at it and its in the area of the image that looked 'soft' in just ha.

Will have a go at processing a quad band versions as soon as I can.
