Tried another series of shots through my 94mm f/7 telescope using my a6000 at prime focus. Used an intervalometer to take a series of 20-30 sec exposures at iso 3600-4000. I think in the future I'll drop it back to iso 1600-2000 because even when the 20 frames were stacked, the results were a little noisy. I'm happy with the results especially since I'm still new at this.
Pictures are of M31 - The Andromeda Galaxy. After achieving proper focus I realized I should turn the camera 90 degrees in the focuser to get the whole galaxy. I was afraid of losing focus rotating the camera so I took the series anyway. Two of the main galaxy's companions, M32 and M110 are in the field. Core is a little blown out. There's a star cloud on the left side that has it's own catalog number - NGC 206
Second is the Lagoon Nebula - M8, and is in the Southern Sky. Surrounding the bright nebula are some dark areas caused by gas and dust blocking background stars.
Third is M17, The Swan Nebula, not far from the Lagoon in the sky.
Fourth is Comet Panstarrs K2, the GIANT comet that was in the news earlier in the summer. Its sporting a short tail.
Finally, is M101, a face on spiral galaxy near the handle of the Big Dipper.
All images were stacked in Deep Sky Stacker, and had some levels or curves adjustments in Affinity Photo.
The images do show some vignetting because I haven't had any luck taking good flats to stack with. For some reason, I getting flats with gradients top to bottom.
Enjoy, Tom
