Sh2-155 (Cave Neb) HST

[ChrisLX200]

It's been like banging your head against a brick wall with this one, what with a bright moon and thin cirrus to deal with. Feels better now I;ve stopped    I have learned something though - don't bother imaging faint stuff under such conditions because more data really doesn't help. I captured 19 x 20min Ha, 12 x 20min OIII and 10 x 20min SII, and of that I chucked over half away because of a light background and washed-out details. The rest is still poor but I stitched it together regardless. Any improvement is going to have to wait for a darker and more transparent sky.
