Just as an fyi Mike this is the rotator I use #19630 - Pyxis LE - Camera Field Rotator optecinc.usThe Wanderer looks nice as well. Especially the price. What I can say for the Pyxis LE is it's being

Hi Mike, regarding low profile rotator you can have a look at wanderer astro ( https://www.wandererastro.com/en/h-col-126.html ). I got their mini version for my equatorial classic astrophoto rig. It

It just means I'm outside for the entire session, rotating the camera, changing the filter on the slide, tweaking the focuser and collimation, checking for dew, launching another live stack. No

That's a great way to do it ... g.

Hi, My approche is more manual. With my 20" f/4 Obsession and CMOS camera (ASI294MMPro), I take 5 minute live stacks, with 2 second exposures for each filter then manually rotate the camera using a

You need derotator software for the rotator. Mickey

I had tried a Pegasus Astro field rotator (the first version) but could never reach focus with all my other stuff in my image train (like starizona nexus reducer/corrector). I ended up selling it

Hi Gabriel, and yes short exposures using some form of deep sky lucky imaging work very well with dobs doing Astrophotography. If I ever get back at it again, the move to Fl has really set my time

I use the Optec De-rotator system and watch the time of the exposures.? Mickey

Hi Tony, You have some options: Lucky imaging takes a bunch of short exposures and you align/derotate post prcessing. Let the camera software align and stack your image. I use option #2 since the

I limit my exposures to 10-20s depending on where in the sky i image, it helps that i live 63 degrees north. My setup is already sky fog limited after only 20 seconds despite using a DSLR, so taking

What do you dob astrophotographers do for field rotation? Do you have a rotator or do you just limit exposure times? I have an 18" SC/AN equipped dob and I'm looking into getting started myself.

Frédéric, I just use my imaging camera for the 2-star alignment step. ?I have a remote handpad to slew the scope close enough with help of a telrad and center the star on my remote laptop screen.

Hi Sevan, I am the guy with an UC22 Servocat / AN trying to start astrophoto with my dobson. Servocat is connected to the PC in USB (servocat 3) with one of the ASCOM servocat driver. Regarding how

Hi Gary, thank you again for your quick answer. I am confident now not to be in a hurry to clutch the servocat drives just after the alignement and will not be stressed if the planetarium software

Frederic, Good day sir. My response is inline below... have a great afternoon. g.

Hi Gary, I am glad to ear from you. I own two obsession telescopes equiped with your system, one old classic 15 with version 2, and the very first UC22 with version 3. Still working like a charm and I

PHD2 can measure Dec(alt) backlash which would include the whole system so if it's within 10 arc min i assume you could enter the precise measured value in ServoCAT sky. I only have this issue in

Frederic, Good day sir. my comments are shown intermixed with your note to George Hilios:

Hi, here is an update of my first experience. Episode 1: for VISUAL Use first: remote wireless slew and center to a target with NINA connected to a UC22 Servocat Argonavis with the servocat ascom
