  1. If it's anything like my car it will chop power after 30 minutes. Why bother with an inverter? It is an inefficient way to power things- a) The mount is most likely rated for 11-15volts DC. b) The laptop likely requires 12 to 19volts depending on model/make. c) Inverters incur losses with heat etc. I use one of these for my laptop - https://www.amazon.co.uk/Lavolta-Panasonic-Cf-aa1653a-Cf-aa1653am-Cfaa1653am/dp/B00H3ROTV4/ref=sr_1_1_sspa?ie=UTF8&qid=1535412763&sr=8-1-spons&keywords=12v+laptop+car+charger&psc=1 And power my mount from a 12volt battery through a fused cable.
  2. I captured this HH back in November 2017 I know it's not the 6nM filter but just for your perusal. The Horsehead. 12 x 5 minute subs in Hydrogen Alpha. SW150p + Starlight Xpress SXV-9H + Astronomik Ha 12nM filter. False colour added.

    M51 Hypercam 183 firstlight

    I found that as soon as PHD or anything else was in use on the laptop I got the blue screen of death! I now use my small netbook for EQMOD and guiding and my laptop (USB2) solely for capture/camera control. I always use 12 bit captures.
  4. My old 8x50 finder focuses by turning the objective end of the finder.

    Lunar Imaging with a RED filter (Why)?

    Have a read here - https://www.firstlightoptics.com/uv-ir-filters/astronomik-proplanet-807-ir-pass-filter.html I have the 742 version and it does make a big difference.

    Old Starlight Xpress ccds?

    I ran my old SXV-H9 on windows 7 & 8 no problems.

    The end of LP filters?

    I have found here in Northants that the LED lights have improved the LP situation and most LP is coming from industrial units with misdirected lighting. The best nights to get an idea are misty nights when you can see the light beams.

    how do I find ADU values?

    Sorry, thinking of Neb3

    how do I find ADU values?

    I don't use GIMP but if it's like photoshop there is an info window you can open and it gives you the value of the pixels where your mouse pointer is.

    Fullerscope Mount

    I believe Sir Patrick Moore had one of these with a 5 inch refractor on it.

    Polar misalignment!

    I used Sharpcap Polar routine and got the errors down to 1" on each axis. Pointing at the pole and rotating the RA confirmed it was good as the stars all streaked in line with the reticle circle on screen on long exposure. PHD2 however keeps going on about DEC backlash and has done so on both my mounts, I find the original PHD guides far better without complaining!

    EQ 6 problems

    Glad it is sorted, mine uses Prolific chipset in my eqmod adapter and usually self installs. Never use my handset....EQMOD is the way forward.

    HEQ5 (Black) Hand Controller Problem?

    Normal. Going East is the direction Earth rotates, therefore stopping the motor allows the Earth to move your scope (so to speak). The reverse switch corrects this if you are the southern hemisphere.
