Hi ala_eh
Good first shot with the DSLR. If you can get away with longer exposures I would recommend it as the horsehead is dim and adding more short exposures isn't exactly the same as fewer long exposures for the same total time (each image adds read noise and if the image isn't much above the minimum to register the signal the read noise will add up.

Thank you for looking and taking time to comment. I will definitely try doing longer exposures as you suggested.

I think I may have had one of these cameras. Was it the first with auto focus?
As far as the picture goes, it shows some extreme light/dark areas. Which can be interesting under the right circumstances.

It was their final manual-focus SLR series before the auto-focus Minolta Maxxum 7000.

A gorgeous landscape - my only suggestion might be to remove some of the blue cast from the foreground and mid-ground mountains - that could whiten up the snow and might give more depth to the image. IMHO, of course...
Thank you. I will try your suggestion
