I think I have the DSS end sorted out now. We'll see what they say. Basically, I registered the Red set with the reference frame checked, and then stacked with it unchecked. That gives me a tipped-in-the-frame Red stack, which does appear to add just fine to the CLS-CCD stack in Layers now. The tipp...

Hi Ivo, Almost. The instruction from the DSS forum was to pick a reference frame (light) in the dual-filter stack, and then use that same frame (unticked) as a reference frame for the second stack. So a particular light, not stack, gets used as a reference. I picked the highest-scoring one from the ...

Well, I just opened a post on the DSS support group...

Sharing a common reference frame for both stacks isn't conforming the output sufficiently.

Here's what the two stacks look like when combined in Layers...artistic, but not exactly what I was hoping for.

Ah! Different sequence of ops than I expected.

So... Blend the two stacks in Layers while still linear, save the blend, import via compose and carry on as usual. That sounds almost straightforward.

Ok. I'll update this thread with results - might be a few days.

Thanks!

Thanks, IVO! Well, I'll play with it and see what I get, but I really wonder if the alignment and registration won't turn into a complication. I've got instructions on how to set a reference frame in DSS, so that should be ok, but I usually use intersection mode, so will the second set come out the ...

Thanks, Ivo! In this particular case, I'm shooting an emission nebula with a CLS-CCD filter that produces a really nice result. But I'm doing it with an unmodified camera, so a top-up of reds might help offset that as well as add to total integration time, and that's what I'm trying to mix in with t...

Hi Ivo, I'm trying to combine two differently-filtered data sets, and it's not going well - can I get some advice, please? I recently captured about 4.5hrs on the Heart Nebula, using my unmodified D5300 and an Optolong CLS-CCD filter. This is a dual-band filter: one band of blue/blue-green, and one ...

Ivo, Ok - I had dialed back to RA only and not terribly aggressive. I'll go back to spiral and dither more frequently next session. Thank you so much for your help and advice with this! Gaetano, What Ivo said :-) The image was taken with a Nikon D5300, a Hotech field flattener, an Optolong CLS-CCD f...

Thanks, Ivo!

Actually, I did dither. Just checked my guide log, and there were four dither events in that session.
So...if that's the source of my mottle, that leaves me wondering whether I needed more dithers, or more aggressive dithers, or both.
Any ideas?
