Hi all,

I know that some folks are producing appealing astrophoto with their obsession telescope. Having started astrophoto with a classical setup (Equatorial mount + small refractor then 150mm newton) I am now motivated to try it with my Obsession UC22 Argonavis/ servocat 3 last firmware.?

I would like to check with those members having done it already, if what I plan to do is going the right direction.

?

I am going to install a guide camera and scope as well as a main imaging camera on my AN/SC UC22 (hope to reach focus with my integrated paracorr SIPS).

I plan to connect my PC (a mele quieter sitting on the scope controled through wifi with Remote Desktop) to servocat as usually recommended for AN/SC configurations (cf chapter 8 of servocat manual). In this configuration I understand that servocat is passing to AN some of the request sent by the ascom driver after converting it to the AN/SC interface specific langage.

I already made a first test with this configuration and was able to establish the connection using the new servocat ASCOM driver (2022) from?.

Here is what I plan as my setup procedure.

1 turn everything on

2 do initial 2 stars alignement with Argonavis as I would do for visual use

3 clutch the servocat motors on both axis

4 connect NINA to all my equipments (imaging OSC camera and servocat) and PHD2 to the guiding camera ( is the must have software to control everything for astrophoto sessions before going to bed ;-))

5 turn AN catalog to "from planetarium"

6 choose a target either directrly from NINA or from planetarium (connected to NINA)

7 slew and center from NINA: I expect AN/SC to slew to the coordinates, and NINA then triggers a short capture with the imaging camera, platesolve it and loop to center the target dead center and synch the AN/SC to this location in the sky and track it.

8 I have noticed that the servocat Ascom driver supports Pulse guiding so I expect that PHD2 will be able to guide assuming that I will have to calibrate PHD2 for each new target as the guide speed will translate to different "sky speed" depending on Altitude and lat/long position. (the advance sequencer in NINA allows to trigger a guiding calibration before imaging a new target if necessary)

9 run my imaging sequence (n images x t seconds.

10 alternatively I would like to try sharpcap to perform some EAA live

11 alternatively I can just use the guiding camera as the main camera and use my scope in visual mode but have the automatic slewing and centering whithout spiral seach or switching back to wide field low magnification

?

Does it sound right for those having already the experience to do it?

By the way another motivation to use NINA is that there is a new app ?application that let you command NINA remotely from a a simple smartphone, once you have launched the PC with NINA.

I will try this week end and let you know anyway.
