  1. 1) Nope, you use existing software called INDI. No programming required. 2) You dont need a screen in the field. You leave the raspberry outside with your scope and connect it to your home network somehow (WiFi, or better, network cable). You generally install Kstars (with INDI) on your computer in the warmth of your house, and then use it to connect to over the network to INDI running on the raspberry pi. 3) look online to see if there is an INDI driver for your focuser hardware (https://www.indilib.org/devices/focusers.html) 4) I use a raspberry pi 3B, not the 3B+. I use Ubuntu Mate as the OS. I think Ubuntu Mate doesnt work "out of box" on the 3B+, but I may be wrong. I think you can get it to work with some extra work, but read about it online first. You will want to follow some kind of tutorial to set up the raspberry pi. It runs Linux based operating systems, which you may not be familiar with (takes a bit of learning!). Enjoy.
  2. Hi, I'm selling my skywatcher autofocuser. Its in good working order. Make sure it is compatible with your scope. It only comes with the bracket as seen in the photos. Theres a larger bracket needed for ED80s that I dont have! Selling for £28 including UK delivery.
  3. Still for sale! Will add to ABS.
  4. Hi I'm selling my 9 position 1.25" manual filter wheel. It is in used condition and has some minor signs of wear. It is in perfect working order. Price £50 including delivery to a UK address. Payment via Paypal (buyer pays fees), Paypal friends, or bank transfer Any questions, please ask.
  5. I'm selling my 1.25" baader H-alpha 7nm filter. I purchased it on amazon several months ago, but have never actually used it, as my CCD didn't work. (Its just been put in a filter wheel but never used!) As such it is in perfect condition. Price £75 including delivery to a UK address. Payment via Paypal (buyer pays fees), Paypal friends, or bank transfer Any questions, please ask.
  6. Hi I'm selling my Baader 1.25" CCD RGB filters. They are used, but in excellent condition with no scratches or anything of the sort. Price £115 including delivery to a UK address. Payment via Paypal (buyer pays fees), Paypal friends, or bank transfer Any questions, please ask.

    I'm not sure, I was going to take test images to check orthogonality of the sensor. I'm going to use rubber washers under the circuit board to pad it out and allow it's tilt to be adjusted.

    Good question! Well cameras like the QHY8pro use the same sensor, and are still worth a lot of money (new or on the second hand market).. Which is because you can still take excellent shots with the sensor. I'd say that you really need cooling for this project to be worthwhile. Otherwise, you should just astromod a DSLR instead. I'd say that M42 probably isn't the best target for comparison shots - its such a bright target that it doesn't need very long exposure times and wont benefit as much from cooling.. as you say, a DSLR should be able to take quite comparable shots. CCDs have more read noise than modern CMOS sensors, so they will be at a disadvantage on bright targets for which you take lots of shorter exposures. In general though I'm of the opinion that astrophotography will switch completely over to CMOS. I'd like to see a DIY CMOS camera using a modern CMOS sensor. In theory, it could be less hassle as you wouldn't have to worry about analogue-to-digital conversion (and its associated noise issues). If you need anything do ask. I do have spare PCBs I'm happy to send out (for free)

    Yeah PM me your address and I'll send one. The schema I've used is that which is found here: http://astroccd.org/2016/10/cam86/ There are older versions on the Ukrainian forums, and there is an Iceinspace topic on the cam86 -- they have modified the schema and PCB somewhat I believe. I used a bill of materials for Mouser which I found on this page: https://www.diycam.fr/index.php/fr/9-all/construction/5-cam86-fournitures-part-i-la-carte I think as far as the PCB is concerned, the list is generally complete (except for the CXD1267AN, and the optional DHT22), but some components weren't in stock on mouser (and would only be in stock after several months), so I had to substitute some components for equivalents (and get one or two that I didn't want to substitute on eBay). As for using a cam86 as a guider, you can by all means, but I don't think it plays to its strengths. Buying a second hand guider/planetary cam will probably be cheaper than building a cam86! The advantages of the cam86 (cooling, large sensor, low noise) aren't really important for guiders. And the cam86 will generally be larger/heavier and also requires external power (rather than being powered purely from USB like most guiders).

    I can send you a PCB if you like! M42 is a great target indeed. And of course, you can just go with lenses rather than a telescope.
