Hi all,

 

Last friday as also posted NGC891, here is a 2 pane mosaic of

the quintet of Stephan together with NGC7331.

This is a very interesting area with many galaxies hidden in

the background.

I managed to get 2 panes of 30 x 180 seconds each, managed

by NINA/PHD2/CDC and PS2.

All in all I had a meridian flip ( automatic ), dithering and every

20th frame automatic focussing enabled.

Setup was the RC8 at native focal length ( aprox. 1619 mm ) and

the ASI1600MCC with a UVIR filter, set at -15ºC, gain 139 and offset 10.

All imaged from my favorite dark site ( bortle 3 skies ) some 85 km driving.

I tried to process without pushing too much but hope not to have

overdone it. ( Still without noise reduction ).

I'm a happy camper with the RC8, with NINA and with this image.

What do you guys think??

 

Thanks for stopping by,

 

Mert

Personally this was the first time I tried on this tiny object and

it did come out way better then I imagined.

 

Maybe nice to see the full resolution here:

Really great mosaic, Mert!  You’ve captured some fantastic detail in the faint small structures with perfect round stars throughout.  Well done!

Thanks Jerahian,

 

Most of the work was done by NINA, I only colimated the scope

with the Takahashi colimator and before going to my dark site

I finetuned the colimation a bit with my laser colimator just to

check the tiltplate adjustment.

I am really happy with this great new software that enables me

to autofocus well, I have a hard time with my eyesight I can tell you!

 

Also I've seen that the link to the full resolution had some problem,

you might try again with this link: http://lammertus.epi...-V3-webpage.jpg

 

Hope it works now!!
