Hello,

here is the famous Trifid Nebula captured last week with my SkyVision 400mm (FD/4) at 1600mm without autoguiding and in altaz mode of course. Derotation with the Optec Pyxis LE Rotator.

Subs of 20s with Sony A7S modded (astrodon)

Clear skies

as the weather is bad again.. and again... I've reprocessed M51 taken last year (sorry for that...)

This time I've done it with "Siril" (I've just started to use this soft instead of DSS, and I think the colors are better)

and a final one with some classic objects.

Have a good week-end.

some more pictures of these 2 nights (13-14 march)

Hello all.

I'm back in DSO imaging after a cloudy and rainny winter

Here are some images of this month made in south of France, always with my 16'' altaz dob by SkyVision and the sony A7S.

The results are not as good as I would like but I'm still learning, and have not enough time to practise.

Try to do better next time.

Hello guys,

several months without imaging, and finaly last july during a week in the south of France I had the opportunity to play again with my setup... altaz of course

Unfortunately we had clouds and lots of wind and the 400mm aperture doesn't like it !!

Here are some pictures  taken the last 2 nights...

clear skies

Not enough time exposure but the signal is here anyway

Just the job shows what a large objective can do; do you have a good, dark sky?

Cheers,

Steve, unfortunately no ? Just an urban sky with to much light pollution. I will say M=4 to the naked eye at best. I have to move at least one hour from home to find a suitable dark sky... when imaging home I use the IDAS LPS filter... it helps but above 20s at 2000 iso and FD/4 the image is totally white ?

That's some light bucket! And it shows in the detail you've captured. I particularly like your M51 and M81/82 images. How do you find tracking with such a big beast?

Thanks, tracking with stellarcat is really easy. You just have to initialize the system pointing two stars and you are ready for many hours of tracking. From Time to Time you can re-align on the object but just if you need the go-to.

Interesting topic indeed !

Here is my contribution to the No EQ challenge

All images made with a SkyVision 16" Newton Alt-az with Stellarcat and skycommander .

No auto-guiding, no field rotator in action (althouh I have the Optec Pyxis LE), and 10" subs at 2000 ISO with Sony A7S (Astrodon inside)

Cheers

Michel

Hello,

As the sky is still full of clouds, again and again, and again I don't know if I willl remember how to use this 16" dob one day

And how to connect all this ?

Can't wait for clear skies to image the giant one again...

Wish you all a merry xmas.
