Cave Nebula Bi-color (Oct. 2019)

I was able to add 9x1800" in O3 to the 8x1800" I have in H-alpha.  The two were combined to create a synthetic green channel, then O3 was assigned to B and H-alpha to R.  The subframes were taken with the SXVF-H9 through my Synta-ONTC Newtonian telescope.

Cave Nebula, H-alpha (Oct. 2019)

This is 8x1800" with the Synta-ONTC 203mm Newtonian at f/4.95 and the SXVF-H9, through a 6nm Astronomik H-alpha filter.  This target is very dim.  It could use 12 hours, I suppose.  Nice area, though.  Actually none of this field is merely black sky; it is all covered with faint nebulosity.

NGC281 again (Oct 2019)

This is just 5x1800" in H-alpha with the Synta-ONTC 203mm f/4.95 Newtonian and the SXVF-H9.

Sh 2-132 Hubble Palette (Sept.-Oct. 2019)

This is 16.5 hours of narrowband in equal amounts taken with the SXVF-H9 through the 203mm Synta-ONTC Newtonian at f/4.95.

Sh 2-132 Bi-Color (September 2019)

This image is 11x1800" in H-alpha and 11x1800" in OIII, taken with the SXVF-H9 and the Synta-ONTC 203mm f/4.95 Newtonian.
