Hi, here is my last picture, NGC4565 in Coma Berenices Shot as usual with my 194/815 astrograph with Zen optics + GPU corrector + ASI1600MM with LRGB filters on AZ-EQ6 Luminance : 360*30 sec at ...

Thanks a lot Michael, Just to be clear : I'm refering to FWHM in the center of the frame not to an average over the field (I still have to tune my coma corrector spacing). I measured it with Siril ...

thanks a lot Martin !

Well done Chris, I'm impressed by the depth that you managed to get, this is really something that I should try ! Regarding vignetting correction, you should really use flat frames that take care ...

How dare you spoil so much precious time of the galaxy season ! (just kidding). Wonderful shot, I like the deep red color of Halpha regions and the sharp and colored stars

@Magnar W: in terms of contrast an APO lens will beat a reflecting telescope but not in sharpness. My 8inch reflecting telescope will blow out of the water any 6inch APO triplet in terms of...

Some random example found on Youtube

This is shot with a $350 achromatic refractor (1000mm f/8.3 lens equivalent).

Well, any decent $500 telescope can do the same....

Thanks for your message. Actually urban areas have sometimes surprisingly good seeing. Some of the best planetary image from amateurs were shot from downtown Bangkok or Paris https://www.youtube.co ...

thanks charley for your kind words, Dan

thanks Jared, yes my sky can hardly be worse in terms of light pollution but seeing is often not so bad.

Very nice Michael, lot of fine details and I really like the wide field view with the bright star nearby.

magnificent shot Stefan, I think it really stands out in BW ! (I'm not a fan of SHO false color composites)

nice shot congrats ! What did you use for preprocessing (i.e. stacking) ?

Hi, so after M82 here is its neighbor, still with my 200/800 with Zen optics + GPU corrector and ASI 1600MM from my light-polluted backyard 20km from the Eiffel Tower (1) luminance : 360*30 sec with ...

excellent shot Jared, we never get tired of M51, one of the most beautiful objects in the skies, Dan

Thanks Michael ! I try to shoot M81 right now for a two-panel mosaic but I struggle with the wind and clouds...

Thanks a lot, you're right with modern tools light pollution is not a good excuse anymore not to shoot :-)

Excellent shot Jared, despite the moon your background is good and the galaxies very well detailed. I like the colors too, not too little, not too much saturation.

Excellent shot Michael, with both an expansive field and lot of details ! (this is part of my plans for next week...)
