Image Description and Details: “Jakoby1” is one of the faintest planetary nebulae (PN) in the northern sky. It was only discovered in 1993 by Jacoby and van de Steene at the Kitt Peak Observatory's 2.1m telescope at PG1520+525, an extremely hot (140,000K) white dwarf.
This deep blue central star PG1520+525 is beautifully visible.
OIII is only very, very weak and Ha is almost non-existent.
I used the starless RGB Lum to replace the non-existent Ha.
Designed in HOO with RGB stars.
Tools used: PI, PS. & N.I.N.A.
Exposure and filters: Red 16x60sec., Green 16x60sec., Blue 16x60sec., OIII 14x1200sec.
Total exposure time: 5h 28min.
Equipment Details: Takahashi Epsilon 160ED, QHY268M, QHYCFW3, iEQ45, Lacerta MGEN2, Lacerta MFOC2, Baader RGB, OIII, CMOS-optimized filter 6.5nm f/2.
Elaboration dated 10042024.
