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.

Here's a better one with higher gain and lower gamma.

All Sky camera image captured by Ekos - screenshot of laptop Preview via TeamViewer.

Looks like I should soon be in a position to do all my imaging runs in KStars/Ekos/INDI I'll finish off the all sky cam first as that is nearly done. Just need to mount the focus motor and add the pinion, attach the focus gear to the lens and fit all the dew heater resistors, mount the RPi and connect everything up. Then fit the case together and mount it on the mast. For the main imager, I have a second HAT to add components to including stepper driver, buck converter for the RPi power and some fuses. This will then be mounted in a 3D printed box with suitable connectors added and attached to the imaging rig. I'm not sure yet whether one RPi will do everything or whether I might need two. If using two, I would have one for the mount control and the other for camera, filter wheel and focuser.

Here is a screenshot of the preview window on my Win7 desktop of the Linux Mint laptop via TeamViewer. Here I have the ASC on the windowsill of an open window.

But Preview button from the main control does the same and works fine except that the exposure is wrong - I'm still getting the hang of it all

I'm not pressing Preview but setting an exposure and clicking on Set - that brings up the Preview window.

I was thinking that for my general focuser I think I might have a 2 speed setup with micro-stepping but I would want coarser focussing rather than finer. The single tick mode should be fine for fine focus with faster focus in tens of ticks. The simple single speed focuser should be fine. One channel of the rpibrd control could turn dew heater on/off but I might use two as there are four available and there's plenty of room on the HAT.

The Preview image is on the Ekos machine - in this case a laptop running Linux Mint. Images can also be saved to HD etc. The client machine could be controlled and viewed with TeamViewer from another machine. Otherwise I'm not sure what you mean.

I now have the camera, focus control and heater control working from Ekos using INDI drivers for ASI_CCD, rpifocus and rpibrd
