The Lodestar guider I ordered did not turn up today as expected. So this image was done unguided.
10x120s with 3nm HA, 10x120s with 3nm NII and only ten darks. No flats etc.
I assigned the NII to red and the HA to green. There is a bit of variation between the two but nothing obvious.
The adapter Luke made for means the light path is not vignetted at all by the image train.
Only guided images will show what is really happening in the corners. So far it looks pretty good in spite of the processing.
