    Gina, Are bias frames temperature-dependant? I thought one set of bias would apply to all subs, but maybe I'm wrong?

    Actuially, clicking on the link you have "Installing the INDI library full edition" takes you to the page where you click on "Daily INDI library".

    Gina, Click on download to open html page. Scroll down tot he bottom and click on Raspberry pi. Click on "Daily Inid Libraray". Under Data column, click on download and a dialogue box will open, asking if you want ot open or save. HTH

    At least you managed to get a couple of hours last night ... a couple more than here.

    Which would appear to contradict the previous post, saying it isn't supported. I hope the reply you have received is correct. I must say I am finding the entire process to be a minefield (and that is before I have even started on the "linux" bit). Makes me wonder if it would have been simpler to have fitted a powered usb hub instead ... but then, I would not have been learning so much about my system if I had done that.

    I did wonder, when I saw this the other day, if you had seen it (I think that's the one you've got?).

    Good to know my thinking is in line with yours. When using EQMOD, my mount is very tempramental if I try to attach it through a different USB [like it refuses to find the mount at all], so I was thinking I would stick to specific USB ports for everything. If linux programs are not so "sulky", all to the good.
  8. Demonperformer
    That's interesting. My thought was to have the mount running from one of the usbs on the pi (as the mount has it's own power supply) and to use the other usb on the camera for the QHY5Lii, operating as a guide camera (as that draws its power through the usb port).

    One could also argue that there is a ‘bit of a gap’ between the 55mm (14°) and the 135mm (7.2°) … or even the 400mm (1.9°) and the 1000mm (1.0°). Don’t you just love it when other people are willing to spend your money for you?

    Wow! That 45mm lens will get some chunk of sky. Should give some great results.
  11. Demonperformer
    I think the aim is to keep the camera from sending data faster than the USB system can handle.
  12. Demonperformer
    There, I can't help, I'm afraid. I have only done it in the capture programs.

    If you are running USB2 (which the RPi does) it seems that the USB turbo setting needs to be turned WAY down (like to about 40). The 'hanging' problem seems to be a common one with this camera on USB2. HTH
  14. Demonperformer
    Process of elimination.

    The Ha is great, but what's caused the "splodge" in the upper left of you OIII sub - don't remember seeing that in previous OIII subs you have posted? Was it on all of them? What we really need is someone with access to a walk-in freezer, who can test it in really cold conditions ... or maybe we will get those conditions outside ourselves in a couple of months ?

    Do you have the synscan version or the syntrek version?

    Thirty quid will be nothing compared to it being ripped off again, falling into the observatory through the hold and being battered around by winds trying to get back out again ...

    I know you like making your own , but, if a canon bayonet mount sounds like a lot of trouble, there is an adapter for canon lenses onto the 1600. With your mechanical aptitude, I'm sure you would not run into the sort of problem I managed to create:

    Not only the relative positions, but also the relative brightnesses, the veil being very faint in comparison to NAN/Pelican complex.
  20. Demonperformer
    Been there, done that, T-shirt being printed ...

    Well, I've got zeroes across the board until midnight. And zero is about the size of the gaps between the clouds at the moment!
  22. Demonperformer
    Good! With the breeze here coming from the west, that gives me a little hope the skies might clear a bit later.
  23. Demonperformer
    "Clear Outside" is promising me zero cloud from 7pm tonight until 4am tomorrow ... even now there is a squadron of pigs coming-in over ASDA ....

    Thanks, Gina, I hadn't seen that manual. In truth, I never really did much exploration of the "cooling" aspect of the SX camera, so getting down to -30° will be a great step forward for me. But there does seem to be some sort of discrepency between "40-45 below ambient" (p7 of manual) and only down to -30° for cold winter nights. We shall no doubt find out over the next few months! Also I note that I will be able to use fast speeds on USB2 for planetary, as long as I cut down the capture size. But, as most of our planets will fit on a 320x240 frame when taken through my 8" scope, that should not be too much of a restriction. I will have to do some experimenting, but we are more or less losing Mars & Saturn now and it will be a couple of months before Jupy is viewable in the evening. Thanks.

    FLO website states that the camera has a 'delta T' of "40-45 below ambient". So, come the winter when nights get down to about freezing, won't that mean that we should be getting down to below -40°C rather than -30? Or is there some other limit I am missing? Not that (I suspect) this extra 10° will make an enormous difference at that point - law of diminishing returns? Thanks.
