Manual stacking

[Starwiz]

Has anyone tried manually stacking frames?

I have about 120 Ha frames of M82.  The galaxy data looks good, but DSS is only stacking about 40 frames - it doesn't seem to be detecting enough stars even though I've tried different thresholds.

Thanks

I've manually stacked in Photoshop once (an image of M42 taken with a compact digital camera / eyepiece projection & EQ2 mount, where stars shapes were anything but)... and in Pixinsight I've used the Dynamic Alignment tool to manually align images when my stars were too out of focus to be otherwise be aligned/stacked. There is a 45 day free trial version of Pixinsight, so that might be an option... but it is pricey (and IMHO well worth the cost).

Cheers

You could try sequator. Can you share a screen grab of a few example stars from an image that isn't stacking?

Try Siril simple if you use scripts

Thanks for the replies.  Here's a frame that's not stacking.

Nebulosity also supports manual stacking by selecting the same 2 stars per sub.
