I'm not using guiding with this rig - it isn't needed but if I were I too would use the powered USB hub in the camera for the guide camera and run the mount from the RPi

This is the power distribution and RPi 3 circuit diagram.

A couple of items I was expecting in the post today haven't arrived so this leaves me lacking bits to finish off both HATs for tonight. However, I might be able to "mix and match" and get something sorted out this afternoon. I have only the one step-down buck converter ATM which is currently on the ASC HAT. I think I would really like to get the main observatory imaging rig working with the RPi system and I could either use the ASC HAT for that or move the buck converter across to the main rig HAT. For the ASC I could use the PSU I've been using for the Arduino version viz. an ex PC ATX unit with a 3 core cable up to the ASC and use the ATX 5v supply instead of the buck converter.

Oh yes, I forgot (again) - there is a gap filler between the 55mm and the 135mm lens - I have 105mm lenses at f2.8 I also have 2 Evostar 80 DS Pro scopes with field flattener/reducer giving 600mm at f6.3 as I recall. Actually the 1m FL scope - 190MN - oversamples with the ASI1600MM camera.

Clouds rolled in and I've packed up now. Captured 100 30s Ha subs but there was some passing cloud so don't know how many are any good - I'll see tomorrow.

This is the 60s one.

Heart & Soul in Ha - 30s exposure at a gain of 500 and temperature of -29°C. Tried 60s first but the white saturated - OK at 30s.

There is a bit of a gap between the 200mm lens and 400mm Esprit 80ED scope so maybe I should think about the 300mm f5.6 lens. I've had a look at shorter focal length scopes than the Esprit 80ED but we are getting into the more expensive makes.

I forgot the 28mm f3.5 lens but I need to sort out the field flatness with that. I think I have a 300mm f5.6 telephoto lens somewhere but it's a monster. Here's the new list of focal lengths and fields of view :- 28mm f3.5 lens --- 2103m x 1322m 35° x 22° 45mm f2.8 lens --- 1309m x 1005m 22° x 17° 55mm f1.8 lens ----- 1071m x 823m 18° x 14° 135mm f2.5 lens ----- 433m x 335m 7.2° x 5.6° 200mm f4 lens ------- 295m x 226m 4.9° x 3.8° 400mm f5 scope ----- 147m x 113m 2.5° x 1.9° 1.0m f5.3 scope --------- 59m x 45m 1.0° x 0.75°

Looks like the Heart & Soul Nebulae in Cassiopeia should fit nicely in the 135mm lens FOV

I hope to do some image processing on all the data I've collected soon but I need to make some room for data files. Meanwhile, I'm concentrating on the Linux and Raspberry Pi control and imaging system and also looking into where I shall be going with regard to FOV and DSOs to image. I have a 45mm focal length medium format lens to try out once the adapter I ordered arrives. Here's a list of focal lengths and fields of view :- 45mm lens --- 1309m x 1005m 22° x 17° 55mm lens --- 1071m x 823m 18° x 14° 135mm lens --- 433m x 335m 7.2° x 5.6° 200mm lens --- 295m x 226m 4.9° x 3.8° 400mm scope - 147m x 113m 2.5° x 1.9°

I see... I'm not doing planetary currently and the small camera is for all sky, but I do have an ASI185MC which I might try for planetary some time in the future. I'm currently working on the ASC and also building the HAT circuitry for my main imaging using the ASI1600MM-Cool. I'm hoping I might have something working for tomorrow night when there are some clear skies forecast. I'm looking forward to seeing if the auto-focussing works I shall not be connecting the MS 1,2,3 driver lines - leaving it at full stepping. The auto-focus simulation doesn't work - maybe the real thing will I'm at least 99% convinced that the auto-focussing doesn't use anything but full stepping as there's no sign of any activity on the M0 or M1 driver lines when Ekos thinks it's auto-focussing..

Clear sky for a while and capturing more OIII data for the NAN&P.

I rebooted the RPi again by unplugging from the mains and this time the WiFi connected.

Working now

LAN connections.

Strange - shut down RPi, unplugged and plugged back in (Mains PSU to mains socket) and tried to connect with Putty but no joy. It connected to the WiFi once it was connected by Ethernet and then rebooted using "sudo reboot" from the Putty Ethernet connection but won't connect to WiFi from a cold boot.

WiFi fixed I had "auto wlan0" instead of "auto lo" and a line you haven't got :- iface default inet dhcp Taking that line out and changing the auto has fixed it New file content :- pi@raspberrypi:~ $ sudo cat /etc/network/interfaces # interfaces(5) file used by ifup(8) and ifdown(8) # Please note that this file is written to be used with dhcpcd # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf' # Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet static address 192.168.1.77 # Static IP you want netmask 255.255.255.0 gateway 192.168.1.254 # IP of your router wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf pi@raspberrypi:~ $

Ah yes - I did wonder. OTOH seems there is something different about the 120.

Thanks Dave

Think I was right about the driver - see this ZWO web page.

Do you have the right driver? I have a feeling the ASI120 uses a different driver from later models. I'll check in a minute... Meanwhile... I can't connect SSH via wlan - eth0 is fine. Here's my setup - I have replaced my SSID and PW with s & p. Could you look it over please and see if I've got anything wrong.

Now I need to find out why the WiFi has stopped working - everything working fine with Ethernet connection.

Clouds came in before the imaging run finished so closed roof and packed up. Some more data to add to what I've got anyway Didn't expect any tonight so it's a bonus

Mainly clear tonight in spite of the forecast saying otherwise but with a full moon. Imaging NAN & Pelican in OIII. 60s subs gain of 500 and temperature of -29C.
