Hi,

 

This is an image of IC 443, also known as the Jellyfish nebula. It is a supernova remnant about 5,000 light years away in the constellation Gemini. It is believed this is the remains of a supernova that exploded between 3,000 and 30,000 years ago. It is believed to have created neutron star CXOU J061705.3+222127. This image was captured with 3nm narrowband filters and processed using the Hubble palette.

Re: UGC 11861

Brian Ottum
 

My PlaneWave is good, but very occasionally having communication dropouts.   Could be my iffy USB extender connection, or their grounding wire, or something they just fixed with a new daily build.  Tracking is poor in some areas of the sky, due to my saggy GSO 10” reflector and camera.  Sooo, I will be at DSNM in the middle of November for nearly a week doing lots of maintenance.

 

OTOH, I did have a complete blast taking shots of a NEO flyby last night.  Separate email to everyone coming.

 

Let me know if you need anything done while I’m out there.

 

I’m hoping PlaneWave’s software will track the comet, but have not tried yet.

Brian,

 

Thanks for looking but my system is fairly poor. I just have one of those cheap Chinese RC’s (Astro-Tech but it is the same as the GSO and others). It seems to have numerous issues like the mirror tilts and moves, I have to focus just about every 30 minutes. Mine’s a first generation with the focuser directly connect to the back of the mirror but that issue is ‘fixed’ by an expensive moonlight focuser.

 

How is the PlaneWave mount working out?

 

You’ll love this. TheSkyX doesn’t support the high eccentricity of the interstellar comet (a lot of software doesn’t). This means Paramount users can’t track on it. They supposedly fixed it and it will be in the next ‘daily’ build but it has been maybe two months? I suspect it will be released as soon as the comet is only visible from the southern hemisphere.

Hi,

 

This is a closeup image of NGC 7023, also known as the Iris Nebula. It is a reflection nebula about 1,300 light years away in the constellation Cepheus. NGC 7023 is actually the star cluster in the center of the nebula, LBN 487. The nebula is lit by the bright magnitude 7 star SAO 19158 in the center of the Iris. The nebula is about six light years in diameter.
