Some results from 2 ice cold winter nights; Leo I, M81/82, and NGC2903

Hi there,

Winter has finally set foot to The Netherlands and after about 3 months with nothing but clouds, fog and rain, the skies have cleared at last. Unforunately the moon was out there and getting brighter by the day (or night :-)), but after such a long time catching dust, you'll losen up a bit and just get out there to image as the hunger has to be stilled.

On Tuesday night I shot Leo I, a local group dwarf galaxy very close to Regulus in Leo. Had some troubles with the equipment early on and later on it turned out that my mount had probably received a bump when I was out (volleybal practice). Didn't check it when I got back and started the session. So I ended up with 10x10 mins subs (1 hrs 40 min ISO 800), 11 darks, 20 bias, and 40 flats. Captured with Nebulosity 2.4.4, data reduction DSS 3.3.0 (Kappa-Sigma), and post-processing with PS CS3 (Carboni and Anni's Astro Actions, GxT, HLVG)

On Wednesday night I started with M81/82 for 5 hours (30x10 min ISO 800) and switched to NGC2903 afterwards for another 4 hrs 30 min (27x10 min ISO 800). Support frames: 16 darks, 20 bias, 40 flats and processed identical to Leo I.

Thanks for watching.

Lovely images, I love to observe NGC 2903. It is bright enought to spot with my 80mm bins. With my 10 inch scope I can see four of the stars in your close up! The faintest being the below the galaxy in the image at the bottom of the pic..Mag 12.7 I believe..

Very nice images, very good prosessing and natural look, i like them a lot.

Leo 1 is good catch, i have to try it too, have you tried IC10 in Cas, another dwarf member of our group.

Thanks guys,

It feels good to be pushing the limits of DSLR deepsky imaging.

@Ransu, no I haven't ried IC10 yet, but after googleing it, it sure looks like an interesting target.
