I'm from Hungary. This is my first post. I am glad to be here.
Recently I'm trying to sketch some deep-sky objects. I've made this observation yesterday. Cygnus was near to the zenith and the sky was pretty dark.
NGC 7000 is one of my favourite target. I like to observe it with any telescopes, especially with RFTs and with UHC filter.
Please excuse my language errors.
As open clusters go NGC 2281 doesn't have much to shout about when comparing it to the Beehive Cluster or Pleaides and appears not to be a common target for Astrophotographers. However, what it does have is a name which accurately depicts what you see.
It's a bit of a magic eye moment, but stare at the bright star in the centre of the frame. This is the 'point' of the heart which sits above it.
20 light frames of 100 s each.
15 dark frames,
25 flat and bias frames.

Thank you for dropping by.
Spent the last three nights imaging these three objects. Managed to get them all in the same frame of my ES 102mm FCD100 scope. Pretty happy with how it turned out. I would have liked to have grabbed a little more SII data. When I originally captured it, I thought I might only have two clear nights, so I imaged it as HA/OIII. Turns out there's almost no OIII. On the third night, clouds were supposed to roll in about 4am, cutting the imaging session short, but it stayed clear the whole night, and I got a full night of data with the exception that I got a late start due to technical issues when I first started imaging.
The ASI1600's halos are rearing their ugly heads on the two brightest stars. I tried to tone them down some by desaturating the colors around both stars...it worked a bit.
Another 15 hours and I could probably get rid of any remaining grain, but just don't have the clear nights to get it done. 15.8 hours total imaging time.

Another test shot for brand new lens (same night as other tests of the same lens).
Again, main stars and their colors are not distinct enough.
