Sh2-129, the Supernova Remnant
False color h-alpha
An unseasonal target from last night.
A Starless version to show the nebulosity.
An unseasonal target from last night.Sh2-129 is loacated in Cepheus, next to IC1396.
The field of view is about five degrees wide.
At this time of year it's in Northern sky but can be imaged doe my high
latitude location (65N).
-
It's a dim Supernova Remnant and there is not too many images about it.
I haven't seen any HST-palette versions of it.
If weather allows, I'll shoot O-III and S-II channels to see if there is any signal.
-
This is first image after I fixed the orthogonality problem with my optical configuration.
Now the whole area is flat and stars are pin points from edge to edge.

Details;
-Camera, QHY9
- Optics, Canon EF 200mm f1.8 @ 1.8
- Guiding, QHY5 and PHD-guiding

- Exposures, 5x1200s with 7nm H-alpha filter from Baader,
Darks, Flats and Bias frames calibrated.
A Starless version to show the nebulosity.There is couple of dark nebulae in lower and upper part of the image.
Sh2-129, as a Stereo Pair
I made a Stereo precentation to show how I see this object.Viewing instructions can be found from a Right hand side menu.

An undesignated Planetary Nebula in NGC1499 image?
I have left a report to IAU about this possible undesignated Planetary Nebula.
I spotted this Nebula candidate from my image of NGC1499, the California Nebula,
at 25.02.2009.
