Hyades and pleiades, attempt two

[ralph1]

A second attempt of the hyades and pleiades, this time with dark frames and more subs. I stretched out the subs to 20 seconds each instead of 10 and did 100 of them instead of 60. The dark frames made a huge difference. Sorry about the small image but the compressed version looked far worse and I don't have the computer knowledge to upload images to other websites.

For sub with 20 seconds the stars are with much drift. Where you stack the photos ?
Are you using DSLR cameras, like Canon ? If yes, did you activated the mirror lock up ? For few seconds of exposition the vibration of mirror can cause drift appearance.
For long exposure this isn't so important. At least sould not be !

My Canon T3 cause an earthquake ! Some times you can see stars collision !

I always use the virtual mirror lock up features from BackyardEos.

The photos are stacked in DeepSkyStacker. Yes, I am using a DSLR camera, mirror lock up wasn't activated unless it is activated by default. The camera was on a simple, non tracking tripod.
