  1. I’m interested to know if it is possible to use 1.25” filters with this camera.
  2. The best way to stop Windows updates is to block internet access on the router for the affected computer. Its a standard feature available on any router worth its salt. It generally consists in blocking the MAC address (the hardware address) of the network or WiFi card of the Windows computer.
  3. Sorry! This should be the correct link: https://www.aliexpress.com/store/product/S7959-new-medium-dovetail-telescope-accessories/1371081_1971053752.html It's a vixen style aluminium saddle with a single brass clamp. It has several fitting holes, four of them are 19mm spaced unthreaded holes.
  4. This saddle on AliExpress seems to have 19mm spaced holes: https://s.click.aliexpress.com/e/b6OIEfjL
  5. This is some very inspiring work Dave! I'm also getting increasingly interested into variable star photometry and exoplanet transits. It is a much more empirical discipline if compared to astrophotography. So, whilst waiting for your tutorial I would be gratedul if you could answer a few questions: - You mentioned this work can be done with almost any scope. I am interested in using a small refractor or telephoto lenses so that I can setup everything more quickly and easily. I have an SX-825 (ICX825) that I could use on my FS-60CB (with flattener) but I feel the image scale might not be adequate (3.55 ArcSec/Pixel). - You took 643 45s exposures, was there any interval between each exposure? - Did you also take bias, flats and dark frames? If yes how many of each? - Do you use any particular technique to calculate exposure times to avoid saturating the variable or comparison stars? - Once you set your exposure time do you change it during the course of the session to adjust it against other factors, like for instance the elevation of the variable star on the horizon hence a thicker atmoshpere? I'm looking forward to seeing more light curves! Giorgio
  6. I don’t use Skysafari as my main planetarium software over KStars, but it is really handy in some situations when I’m near to the scope and I quickly need to sass out what targets are within my visible horizon. I’m a bit of a cable freak... All my usb cables are good quality Lindy cables specifically sized for a particular configuration (I have other scopes, CCD, DSLRs and focusers). They directly attach to the Pi. Power cables are also appropriately sized. I use plenty of Velcro cable ties to minimise cable drag. I’m trying to get rid of the mount usb to serial cable by using a Bluetooth to serial adapter but I still haven’t figured out the correct cabling and serial protocols for my mount... I don’t do planetary, solar or lucky imaging with this setup. For solar imaging I use a different configuration based on a Win10 Intel NUC. Focusing might take longer but I’m not bothered. I use WiFi plus, in my opinion KStars feels a bit sluggish when running on the Pi. Plate solving is also much faster when delegated to the instance of KStars on the laptop (I downloaded the appropriate index files). That’s so true, but I also think the client/server architecture of INDI is so much more efficient if compared to ASCOM and the whims of MS Windows. Once the INDI drivers are properly configured, the Raspberry Pi behaves reliably just like an appliance. I took particular care in choosing an aluminium Pi case and attaching a vixen mini dovetail to it.
  7. In my opinion, the best way to use and appreciate INDI is through an OTA mounted Raspberry Pi and a remote laptop or desktop running a separate instance of KStars. Although my Pi has the full INDI/Kstars combination installed on it, I use it only to manage the hardware connected to it and to guide the mount. I run any INDI client software on my laptop or desktop. I don’t bother using VNC or any other Remote Desktop software for two reasons: performance first. Second, KStars is available also for Windows and Mac OS and only needs to be configured with the network name or IP address of the Pi sitting on the telescope to manage it as if it was directly connected to it. Astroberry or Stellarmate OSs can be easily burned on an SD card and deployed on a raspberry Pi in a few minutes! Kstars for Windows, Linux or Mac OS can be downloaded from its website. Last but not least INDI has a Skysafari plugin that allows me to use Skysafari on my iPad to select targets and slew the mount. As I do so, it’s amazing to see the scope position being updated in real-time on KStars on the laptop. In the attached image is one of my setups: FSQ-106, EM-200, Qsi 690 wsg8, Lodestar X2, SestoSenso focuser, Raspberry Pi 3b+ The Rigrunner power socket also has two USB ports delivering 5amps each. I use one of them to power the Pi. I do not need to use a powered USB hub!
  8. I got LASIK last December at the Moorfields eye hospital in London (they have a clinic dedicated to paying patients) and it was one of the best things I ever done in my life! The whole procedure lasted less than 10 minutes for both eyes.
  9. I have a Mean Well 13Amps 12v power supply: https://uk.rs-online.com/mobile/p/embedded-switch-mode-power-supplies-smps/7211658/ placed inside one of these boxes: From homebase: https://www.homebase.co.uk/weatherproof-box-with-4-socket-10a-extension-lead-8m_p395422 i then use a Rigrunner for 12V power distribution: http://hamradiostore.co.uk/rr-4004u-rigrunner-4-way-12v-distribution-board-dual-usb.html Solid performance!
  10. Why don’t you create your own aperture mask? In this way you will also avoid diffraction spikes.
  11. I have a lakeside motor fitted on my FSQ-106ED and using a Hitecastro MountHub Pro Compact to drive it. I'm hellbent on migrating to INDI but there are no drivers yet for the Hitecastro MountHub Pro Compact... I'm in a stage of 'analysis paralysis' deciding between three options: 1- Buy a Pegasus Astro Controller only. It should be able to drive the Lakeside motor since the pinout of both motor and controller are compatible with Robofocus. It seems smaller in size than the Lakeside controller (and 20 quids cheaper). 2- Buy a Sesto Senso. Very elegant solution that incorporates both controller and motor in the same unit albeit expensive at £329. 3- Get a Lakeside Controller. I'm put off by the bulkiness of the box since I want to fit it on the OTA. 4- Get both 1 & 2 or 2 & 3 so that I can fit a motorized focuser also on my other FS-60CB. You should be able to explain my profile signature... Advice anyone?
  12. Hi Gaj, I just saw this thread, I might be late to the party but, May I ask why are you using a WLAN usb dongle on the rpi3? The rpi3 comes already with WiFi embedded. Concerning remote access, the beauty of Indi is that you don’t need to run the capture software via VNC, Kstars/Ekos is now available for both windows and Mac OS. You simply configure it to point to the indi server running on the rpi3. I use vnc only to start/stop indi server via the web manager and phd2. VNC comes preconfigured on Astroberry and you can connect via a web browser.
  13. I'm also using an Intel NUC/Ascom/SGP or an RPi3/Indi/Kstars combination according to the setup. Here is the FSQ106/EM200/QSI setup using the NUC.
  14. Here is the fruit of my new project waiting for dissipating cloud cover: Lenses: NIKKOR 180mm f/2.8 ED AI-s (displayed) or Samyang 135 f/2 Camera: SX-825 Mono Focuser: Hitecastro DC Focus + Skywatcher Motor Focuser Server: Raspberry Pi3 running INDI 1.3 Lens Mount: Geoptik CCD adapter with embedded Baader Ha 7nm 1.25" filter. The whole assembly rides on my Takahashi EM-200 Temma 2M and is entirely controlled by the Raspberry Pi attached on the side. For capture I plan to use a variety of clients over WiFi like: CloudMakers AstroImager, KStars or PixInsight. If I get tired of INDI, the Intel NUC running Windows 10 and SGP can go on the driving seat instead of the RPi3. The FOV of this rig is not particularly wide but, if money will allow, I might get one of those new APS-C sized cmos cameras from QHY due to be released in the future. Also in the pipeline is a an autoguider, probably the QHY MiniGuideScope kit. I will bolt it on the Geoptik adapter itself. Clear skies! G.
