Default New images with W.O.FLT100

Hi to all,

I changed my "OLD" Televue Genesis with a William Optics FLT110f7. I can say
that the quality of the new refractor is very good and better in respect of
Genesis.

Now i can post some examples of my firsts shots using the new OTA, i hope
you enjoy.

Helix (very high polluted region)
http://www.fabioh2o.it/Images/DeepSky/deep72.htm

M27
http://www.fabioh2o.it/Images/DeepSky/deep74.htm

NGC6946
http://www.fabioh2o.it/Images/DeepSky/deep77.htm

and here some other NEW examples
http://www.fabioh2o.it/Images/DeepSky/deep_index.html


I can do also some conclusions about my H9C camera. I can say, after
all my experienced images, that it is wonderfull on emission and
planetary nebulae...less on Galaxy, on which a large aperture is
mandatory.
If you see on last images the NGC6946 it's done like other images
(same or higher time of exposition) but the result it's not on my
expectations. Am i wrong on my opinion?? It is in line respect the
kind of subject ??

I thank you for any comment.

Best Regards
Fabio Acquarone

Welcome back. Haven't seen your posts in some time. That's quite a
collection of scopes used in those images. You do very well with moon
in the sky. I'm having a lot of problems when the moon gets past 50%.
Flats don't seem to work well after that leaving bright and dark edges
to the donuts and gradients everywhere. Your Helix and M27 dealt with
the moon very well indeed!

Glad the new scope is working out so well. It's always nice when that
happens!

I find I do galaxies better than nebula. I figured it was me. I
suppose it could be partly due to the camera-scope combination and the
camera's spectral response. Mine is blue sensitive when taking
luminosity data which favors many spiral galaxies.

I see you used a light pollution filter on the galaxy shot not mentioned
on the nebula images. Stefan used to use one but then decided he got
better results without it and no longer uses it. I wonder if that is
part of the difference. Nebula (if emission as these are) get through
such filters better than broad spectrum objects like galaxies though the
filter may help the HII regions stand out. A little experimentation
might shed some light on the issue.

In any case keep the images coming!

Rick

Thank you very much Rick!!!

I appreciate a lot your comments.
Yes, i use every time the IDAS LPS nas, as you suggested i will try a test
without it with galaxies.

IDAS helps a lot when i am under light polluted skyes, but some test
without it's needed.

Regards

Fabio

Beautiful images Fabio.
If I weren't saving for a new mount I would be tempted to buy a small APO
myself. I have done some imaging with my Skywatcher ED80 scope this and the
last night and it is a quite relaxed way of imaging, I can do 5 minute
exposures without any guiding at all (with the scope at f/5).

Thank you very much Stefan,

i am happy that you can enjot your equipments, it is the best that we can
have during our nights.

5r minutes without guiding is a wonderfull way to proceede, i think that
you can do a lot better guiding...
What camera are you using ??

regards

Fabio
