Multi-color Narrowband in LodestarLive
We start with a live-stack of three 60sec Oiii frames of Thor's Helmet.

Then we change filters to an H-alpha and continue the live stacking.
This is what we get as 3x60sec Oiii + 1x60sec Ha.

We continue stacking another Ha frame.
This is 3x60sec Oiii + 2x60sec Ha.

We reached the file size limit of CN post, so we stop here.
By the way, a third Ha frame would overwhelm the more subtle Oiii. The trick is to use Ha sparingly.
It is fun to watch in live as the metallic helmet transforms into a pink snail that eats up the green vegetation and finally flies away as an owl under the night sky (or in nightly snow fall?). Credit and thanks for the snail interpretation to Martin Meredith and for the owl to an anonymous kid in the dark at an outreach event.
Please feel free to pick your favorite mix of Oiii and Ha.
Equipment used: C11 with an improvised focal reducer, TS filter drawer, Baader 7nm Ha and 8.5nm Oiii filters, Lodestar x2c and LodestarLive v.0.11.
