astro: ngc7662

40x30s, 10" LX200GPS, ATK 16HRC, IR block filter. dew ended the session too
soon... :-(

this is a very bright object, so I started out with a series of 30s,
planning to take longer subs later in the session, but within an hour after
opening my observatory, all scopes were dripping wet and dew made me stop.
too bad. also almost full moon close to the target did not help of course.
still I liked the fact that I captured structure and some red in the nebula.

That looks fantastic! Back in 2003 I took 25 one minute exposures with
my C8 at f/25 using a cookbook camera. Times sure have changed since then.

thanks adriano,
not only did times change, I also changed/learned a lot :-)

I used a 10" (you a C8) but the biggest difference I think is the camera.
Those chips sure are sensitive nowadays. I tried imaging the moon with the
ATK 16HRC through my 80mm refractor, and even at 0.001s exposure, it was
overexposed!

That sure is a nice image Martijn!
Btw you build a beautifull observatory in your backyard.
I moved this year and currently in the process of building my own
observatory (out of stone with a rotating dome).
Hope to finish it this year.

Happy new year to you and your family !

thanks for the kind remarks, Dirk.
Please post some images of your observatory, like to see them!

That came out well Martijn. A good target for short subexposures.
