Hi All,
Here is a recent widefield of M39. I got lucky on Sunday night and had a clear sky with good transparency and apparently good seeing too. Normally this the object is not all that impressive except in maybe binoculars or small widefield scopes. In the context of a widefield photo I think i comes into its own rather nicely.
Heres the shoot data:
Scope - Stellarvue 80/9d working @ f/6 w/a Celestron 0.63 focal reducer
Camera - Nikon D70 @ ISO 800
Filter - IDAS LPS
Exposures - 10 x 300 seconds - controlled by IP 2.0
Mount - Losmandy G11
Guidescope and guider - Orion 120 f/8.3 refractor & ST-4 autoguider.
Processing - Raw conversion, darkframe & bias calibration in Images Plus 2.0. Flat frame calibration and gradient removal in Paint Shop Pro 8.0. Registration and Average Combine in Registar 1.0. Contrast stretch, background compensation and iterative restoration in IP 2.0. SCNR (blue only) in PixInsight 1.0. Final B/W point adjustments, resize and format export in Paint Shop Pro 8.0
