Hello, beautiful picture !!! I saw that you put everything on star adventurer ... you left chasing alone or you had a telescope guide ?? the stars seem well point despite long exposure ...

Hello thank you very much!
You're right, I did not specify well as regards the pursuit!
Now I correct.
In any case I did everything without telescope guide! With a 300mm telephoto to the limit is about 4 minutes to pose, I could not do better! :-D

Hello, beautiful and rich in detail!
It would be possible to see the image processed by Sunblack to have a comparison?
I wanted to ask, how to use the Star Adventurer? I Exhibition of 4 minutes without moved on Orion's belt I can not get them even if I use a configuration much lighter and you would like to know how you have configured or passages that run for leveling, alignment and balance. Thanks in availability!
Have a nice evening!

HelloJonnycorvo!
The picture that I drew upSunblack is exactly the same as I posted this, I just turned down the brightness of a snap! ;-)

Once mounted on the stand and the Star Adventurer oriented polar must mount on top of it the camera and lens, balancing it all with the counterweight. You understand that the balance is correct because in any position directs the camera, she has to stay there!

At this point you have to align the polar well well! I do everything by eye, helping me with this programmino iPhone that the exact position of the polar: [URL =] www.gvarros.com/polaralign_iphone.htm

Just bet the polar lights immediately tracking and pointing at the desired subject, being very careful not to move the whole set-up (every time I point a subject always recheck the alignment to the Polar)!

Now you take!

I'd try a lens from 400mm to see the maximum exposure that we can obtain, probably 180/2 ... wow!

Thank you very much! Even when you adjust the height on the basis of the SA moves to the left and right image?

This escapes me ... wow!


ps forgot ...

At the base of the Star Adventurer is a level ...
Always make sure that everything is always "on the bubble" before aligning with the pole! ;-)

I try to explain better: When you point the polar using the three knobs of the base of the star adventurer. Using the knob that moves the vertical axis the star adventurer tends to "dance" a little 'and also tighten the lever to lock the Movento decreases this game but never eliminate it. At least on my ... and this complicates a little alignment!

Now I get it ... when I squeeze the lever to lock the vertical movement, everything remains stationary.
Obvious that if efforts much some moves, but once locked if not touch remains steady.

Try to squeeze better clamping lever, has a life inside, perhaps the game!

Beautiful, bravo. Excellent tool the Star Adventurer, with a focal length of 400 I'll try 'early, but I think that without guidance 180 sec is already' tough ... The important 'solidity' of the tripod, fundamental ... my opinion. Hello

Thanks! Try ', even the guy who sold me Teleskop Express sa suggested to me before the same thing. Meanwhile, I've got the bar and counterweight.
Thanks again!

Well if you did not have the bar of the counterweight the reason of the failure was definitely that! wow!
It 'a very important thing, otherwise the engine struggles a lot and so it is not accurate!
