Recently I bought a Canon 6D for daytime photography. Of course I was going to put it one day behind a telescope.

Said and done. Last weekend I went to my girlfriend's parents' village (Clear Outside estimates an SQM of 21.9 there), I put the Canon 6D behind the Esprit 80 and both of them on top of the tuned AZ-EQ5. Guiding was done with a finder guider and overall stayed at 1.5"-1.8" RMS. But the 6D has large pixels and I also downsampled the final image so there shouldn't be much loss due to poor tracking.

Moon was rising just before 11 so I started early, shooting Orion as the first panel. 2 other higher panels followed, consisting of 21, 21 and 19 subs, 5 mins exposures at ISO1600. For the Orion's core I used also 12x5s. That's a total of 3 hours.

The stars towards the corners are not perfect with the Esprit80 and a full frame sensor, but resampling at 60%, I do not notice any weird shapes.

Can't wait to shoot a wide Antares region with this setup.

Really nice. I can’t wsit until late autumn for Orion to be back at his best - hopefully will have got a lot more hours of imaging under my belt then and will have a go at a nice widefield like this. 

Even if it is only half as good as yours I’ll be happy :)

Really nice image Alex! Could be taken for a mosaic. You may consider getting a Ha clip on filter for that camera to add HA to your RGB images during moon lit nights.

Excellent image Alex and nicely processed too .  Can I ask what intervalometer you used for taking your frames ?  Ive also recently purchased a 6d and fancy attaching it to the scope or a few lenses.

Kind regards

Mark

Thank you, Mark!

My mount performs poorly and I can't take more than a few seconds unguided shots without trailing. I used a laptop for guiding and also for exposures control.

When I used my 6D, I bought a cheap one on Amazon. They are very simple and work well. https://www.amazon.co.uk/s?k=intervalometer+canon+6d&crid=3L2SRCXPQYHPO&sprefix=intervalometer%2Caps%2C178&ref=nb_sb_ss_i_6_14

As you can tell from that search, they are essentially all the exact same, with different branding. Probably made in the same factory in China.

Absolutely stunning image Alex. Is the 6d is modded in any way? As old as the 6d is I'm half tempted to pick one up for travel as seems more HA sensitive than my Sony a7r3.

Thank you! I used an unmodded camera, but really good skies help a lot. There's a lot of dust in Orion though, not only Ha.

The last version with ~double the exposure time is this one:
