I can't begin to explain how rare this is up here! Very good seeing happens like 10 times a year and fair to good is the norm. Excellent seeing is unheard of! :ooo: Probably explains why there are so few planetary imagers in Norway! :lol:

Too bad my DMK is still in the post :(

Anyway, my best image to date! (Resized 150%)

Chris, Great image! Congradulations on catching the best seeing. I am still waiting for 4/5. Definitely save those avis.

Regards,
Steve

Thanks, so do I ;) I can drag out a bit more detail but then with more noise. I'll settle for a smoother image.

Thank you all! I actually processed the second one :p The first one was posted in a "I got perfect seeing! *dump it on the net*" rush :grin:

Thanks!

Yes, Im now very happy with the telescope. When I first got it, I compared it to my friends Orion 6LT. The 6LT had no problems following the 2x more expensive Europa and it didn't require any mods - NOT impressed!!! :mad: Now I know that when the seeing is good, the Europa will pull ahead. And it doesn't matter what magnification Im using, the image just snaps into focus. I can't say the same about the 6LT ;)

Hi!

I read your reply in my post!
You have some really nice pictures here!
I can see that the seeing must have been outstanding!

Also nice to see that you can get a nice result as that with an 150mm Newtonian!

I also have an OO Newton, my 8" is a f/6, I guess it will produce a "softer" image, compared to your 6" f/8.
Like you, I had to modify some things on my scope, before I was satisfied with it:

http://www.astrogotl...ace_focuser.htm

and:

http://www.astrogotl...mark_mirror.htm

I haven´t had an opportunity to really try it out yet, due to our EXTREMELY bad weather conditions here in the Baltic sea...

I am also curious to find out what difference the 1/4 PTV mirror in my 8" scope will make compared to my friends OO 8" 1/6 PTV, when imaging the planets!
As you wrote, it is a matter of the seeing conditions too...

At last, again: very nice pictures you got there!
Thanks for sharing!

Hjertlig hilsen fra Gotland!

//Roger!

Tusen takk Roger!

Yes good seeing is very important. Unfortunately we rarely get that up here :(

Im actually thinking about upgrading to your telescope. I love the OO optics but Im not fussed on some of the mechanics and design.

I am currently redoing the site so all my latest images can be found here.

Chris: My scope is an older one, bought from the widescreen centre in London.
Its the black tube, with a two legged secondary support(!).
It has the same mirror cell as your scope, a 1/4 PTV mirror and originally a very tragical 1,25" focuser.

They had it up on sale for 399£, including a Vixen GPE.
As you say: the optics are great, but the design and mechanics are done "the British way"... -functional, but crude.

I had expected more from my Vixen ED100SF as an imaging scope but I guess that Saturn is a hard target for a "smaller" scope , due to its great distance and small apparent f.o.v. On the other hand, it excels on the Moon with extremely sharp and crisp images. And its a great allrounder!

The major advantage with an OO Newtonian, is besides the good optics, its low weight due to the aluminium tube.

I attach a picture of the scope on the Vixen GPE. As you can see, its a rather big scope. But due to its lightweight tube, the GPE handles it fairly for visual use.

/Roger.

Thank you all - keep wishing the good weather this way! :lol:

Roger,
I had a 10 inch once so your 8 inch is tiny! :p Nah, I know. Same length but considerably more bulk. Im still on the fence about upgrading. I really like what I have now, but that might all change when Mars comes back (aperture RULES man!!!)! :grin:
