I am not able to find guidestars most times with DUO and Edge 8 and 0.7x reducer. hardly one or two blurry instable stars, and loses quite often. not able to even calibrate at times. focus on main camera is tact sharp. tried increasing gain and exposure no luck. tried turining fine focus knob of DUO no luck. am trying on galaxies such as whirlpool, bode's and cigars. can you (or anyone else on this thread) help what am i missing please
I use mine on a Stellarvue SVX90T at roughly f6.5 and through Antlia ALP-T dual band filters. No problem with finding guide stars and guiding. You may want to drastically reduce the max calibration on the Dec and RA from 2000. Your guiding will improve. Try starting at 150 and creep up as needed.
What a great idea! How come no manufacturer thought of this before? I have the 2600MC as my main DSO camera and I love it. But I have the OAG-L on the back which eats up back focus. Now I have to decide whether I can afford to buy one of these and sell my 2600 and my OAG! Thanks
Great video Antoine, as always!👍A few quick points: (1) In addition to Nico's review, everyone should check out Ben Chappell 's very thorough testing of the ASI2600MC-Duo on his YT channel, "The Narrowband Channel". He used aperture masks to change the f-ratio of his imaging rig & challenge the guiding sensor's ability to find stars. Very interesting results! 👍 (2) The 'random' part of Cygnus that you imaged contains 'The Dolphin Nebula", which is close to "The Propeller Nebula". I have always imagined the dolphin swimming just behind a boat, among the waves of the ocean (all the nebulosity in the area). 🙂 p.s. Congrats on APOD #2 !!!😀The Blue Horsehead is one of my favourite objects in the sky, and your image blew me away! 👍👍 p.p.s. Dalia, I hope your hangover wasn't too painful! hee hee! 😉😁
Hi Thank you for the review. My Duo could not guide when I used the following: - L-Ultimate -CDK 12.5 (2540mm, F8) I tried guiding subs of 1 to 8 Sec and boosted gain but it did not work. Stars were barely visible and could not guide for more than a minute. I realize that these conditions are very difficult for guiding. Thanks Sam
I wonder how soon other cameras will come on the market that also have the guiding chip built in -- either more kinds of ZWO cameras, or products from other makers. It seems to be the obviously correct way to do things.
I've been using mine with the L-Ultimate (3nm) on my F5.9 scope with no issues so far. Guiding has been between 0.5 to 1.

I'd love to see more testing with the Optolong L-Ultimate. Especially since your bortle is just as bad as mine here in Phoenix.
How does that guiding function during auto focusing during sessions? Does it screw up the guiding at all then?

Has anyone tested the guiding with the ASI2600MC Duo with a C8 at f/10?

Salut les amoureux dites , vous n'avez pas sortie cette vidéo en français par hasard ? 😁
The SNR is better with just one presenter.
love it
Have ZWO improved the quality of their USB cables? The red looks like it's a bit more robust than the old black ones.
