(IAAC) V1016 Cyg (PK 075+05 1; PN?G075.1+05.6) - 8inch F/10
Observer: Yann POTHIER (France)
Your skill: advanced (many years)
Date and UT of observation: 18 August 1993, about 01h00 UT
Location & latitude: La Clapiere Obs. (France, latN44 40 00, longE06 27 36)
Site classification: rural, alt.1650m (5500ft)
Limiting magnitude (visual in UMi): 6.1
Seeing (1 to 5 - best to worst): 3
Moon up (phase?): no
Instrument: Meade SCT 8"/203mm F/10
Magnification: 87-312x
=46ilters used: UHC, OIII, visual spectroscope
Object: V1016 Cyg (PK 075+05 1; PN?G075.1+05.6)
Category: Planetary Nebula ? (Innsbruck database: possible PN)
Constellation: CYG
Object data: Vmag=3D10.3; dim.?; type I; central * Vmag=3D10.3 (Mira type
variable mag.10.0-17.5); ELCAT: [OIII] (495+500) =3D2.5 x [Hb] (486nm)
RA/DE: 19h57.10m, +39=B050.0' (2000); Uranometria 84
Description: at 80x with spectro., the spectrum looks continuous with
emission "lobes", specially the OIII lines, quite visible (located with
OIII filter behind the spectroscope device); at 145x, the OIII filter
isolates quite well the suspicious "star" which looks still stellar at
312x; a mag13 star is 30"S.
I can provide a scanned drawing of V1016 Cyg to anyone who can read the
binhex encoding of Eudora (for Mac); just mail me to try
(ypothier@abi.snv.jussieu.fr), it works sometimes with other
configurations...
