Final digital sketches

Apologies for reposting this, but only after 2 weeks of reworking the
sketches in Photoshop I am somewhat satisfied with the sketches I've
made. (I don't like half-assed jobs :-)

Some issues, in particular the actual brightness, cannot be objectively
depicted, unless one considers averted vision to be part of the
obesrvation. This is the case for M57, M33 and M82 for example: No way
the instruments could show such luminous images without averted vision
is used. As such, keep in mind that these sketches are basically
depicting what one would see using averted vision.

Enjoy.

I did! Thanks very much.

I have long wanted to do something quite like this, but just haven't
found the time. I'm glad somebody did.

Wonderful sketches, thanks for sharing. Very nice. How exactly do you
DO a digital sketch? Do you sit with your laptop near the scope and work
with photoshop or some other drawing program? How do you maintain your
night vision?

Excellent images and a very worth while exercise. If you squint at
the monitor, you can almost be there ;-)

Thanks. Yes, I forgot to say that. The best way to view these is to
actually squint a little.

The star field and the object's angular size are picked approximatelly
from CDC. For the actual object details and brightness, wannabe artists
have a relatively strong visual memory, which is retained for many days
after the observation. I'd say that the brain also has a relatively
powerful *relative* brightness memory retention as well.

Add to that details from an observation report, and there you have it :-)
