Final Process - NGC7000 3x3 Mosaic (Ha Only)

This is the largest mosaic I ever done - the size of the final image is 8489 × 6123.

NGC7000 is a large target and took me 15 nights (48hr) to collect enough data from my Fremont backyard. Required 3x3 mosaic to cover this...

I can barely see a shape here...

Very tough target. I will target on this next year !

Just a quick shot from my front yard. Want to see how much LP would I get with L filter...

Here is a photo I took at 11pm and 4am without doing re-focusing...
You can see it is off by a lot !

2017 New Year Project -- "Portable Observatory"

Want to do something like this for a long long time. Having two young kids really limits my go-out-to-do-imaging time. People said having a semi-permanent setup is the next best thing to an observatory. So I pull the trigger... !!

I really should do this earlier !!!

Take me 5 min to setup and 5 min to tear down.

Although I have very limited sky in my backyard, I think I am going get a lot of subs this year.

365 cover ...

Very limited sky ...

First light -- Thor's Helmet Nebula - Ha 30min x 3 and the target is blocked by the tree...

 Second light -- Rosette Nebula -- Ha 30min x 7 ...
