Sequence which rotates filters in between dithers

[Shlomi Vaknin]

Hi,

For a few reasons, such as comet or minimizing dither time, can we have a method of cycling filters between dithers?

e.g.

• 2 Red
• 2 Green
• 2 Blue
• 2 Lum
• Dither, cycle 30 times

Would take 60 frames for each channel and dither every 8 shots.

Are there plans for this, or is this possible and I just missed the FAQ?

Thanks!

Any comments on this? Is this currently possible? Is it planned?

See for example this comment on Cloudynights https://www.cloudynights.com/topic/573886-sub-exposure-tables-for-asi-1600-and-maybe-qhy163/?p=9173794, where interleaving filters in recommended.

Just set up a sequence of 30R, 30R, 30G, 30G, 30B, 30B, 30L and 30L, set sequence mode to loop and enable dithering only on the last L entry

[Shlomi Vaknin]

Oye, totally missed the sequence mode! I will give it a shot, thanks!

@Stanley Dimant, I tried that (with latest build), but the sequence just stops after the first round.. What am I doing wrong?

Thanks!

It needs more than 1 total images per filter.

[Shlomi Vaknin]

Interesting, Ill give it a shot. Thanks! Is this process documented some where?

[Shlomi Vaknin]

Finally got around to trying that. Still does not work…

Can you perhaps share a screenshot of a setup that works for you?

[Stanley Dimant]

Your screenshot shows both sequence items with the same (no) filter. Of course looping won’t do anything then. It will also only take as many images as you set up in the total field. Refer to the docs https://nighttime-imaging.eu/docs/develop/site/tabs/sequence/
