Great! But 180s exposures for plate solving is... a bit long.

For plate solves, I do 5 second exposures through the luminance filter on my 130GTX @ f/4.5. Do you have some really slow optics where 2 minutes is needed?

And one last note on my first use of the Mach2/APCC/APPM with a color camera.

I did an “all sky” map with 65 or so points. I took 95 x 180s unguided subs on both sides of the mount. All 95 subs showed nice round stars and all 95 were used in the final stack.

The Mach2 + APCC is very impressive.

I had a couple of clear nights that allowed me to obtain OIII and SII data to compose a color image of the Veil. data is 3 hours each of H-a, OIII and SII data.

https://www.astrobin.com/full/xdvfcp/0/?real=&nc=Uncarollo

Of those frames, they consist of 600 sec unguided subs in OIII and SII. The Ha consists of three 1 hour guided subs. I had 3 more hours of Ha taken on previous nights that I did not use. I had a strange situation that i could not figure out at first, each of the subs had rotated about 5 degrees from the original framing. I finally checked the camera and the threaded coupling was loose, so the camera slowly rotated with gravity.  I tightened it up and put tape on the seam. Live and learn i guess.

For the Hubble Palette I used SII = red, Ha = green, OIII = blue

Hi AP and Astronuts,
I continue my search for objects with my C11HD and my QHY294c and to improve the tracking, readjust the polar alignment and redo the modeling (91 successful / 92).
On a series of exposures on M2 (74 of 60 seconds) I noticed a drift only in DEC, 8 arcsec in 74 and I noticed on the model a marked orthogonality defect in DEC. I am therefore looking for ways to explain this defect.
Installing the C11 on the mount? fixing the camera? ... What in general causes this defect?
 Best Regards
Dominique

These new backlit sensors are amazing! Of course I would want the 64MP version and couldn’t settle for the 2MP version. Nice to see these advances being made, I just need to save a few more coins to get one.

This is the same camera that I'm adapting for my all-sky camera.

If you're curious about its NIR response, talk to Christopher Go, who has been posting some really good methane stacks of Jupiter made with this camera and its IMX462 sensor.

At about 25.45 on the video.

The entire video is interesting and he does go through the evolution of the CMOS detectors.

FWIW, the IMX533/571/455 series are evolutions within the Exmor R (fifth generation) family. Sixth generation refers to sensor designs within the Exmor RS family, the "S" denoting stacked silicon design.

I am trying to do the same, but more pedestrian, compared to yours, for my feeble brain. ZWO 290 with the same lens in the Unihedron enclosure. Let us know how yours goes!! Always looking for better options.

Would you be willing, once operational, to share your wiring diagrams for those of us who can solder but not design?!

The ASI2600MC color camera came in.  I am doing a point mapping run in APPM.  The camera is connected to Sequence Generator Pro and is using the on-board version of PlateSolve2.

Everything appears to be working fine using the color camera.
