    Despite what I said - some things were looking rather large so I have tweaked a little more, hopefully it's a bit more consistent now but if there is anything else people notice, please report but please post a screenshot so I know exactly which bit you mean.

    That looks a bit more balanced for me at 100% zoom now.  I reckon I can go to 90% zoom and it should be pretty much ok.

    I rarely use the mobile version, but am finding the desktop font sizing a bit much. Section and topic titles are a bit too big, reducing the number on screen without scrolling. I don't run the browser full screen and reducing zoom from 100% will make all other sites I use unreadable. Not using any customised views as I've never looked, just whatever the SGL default is when I open the site.

    Yes, I've reduced the page to 80% zoom in Firefox and that works better for me for all the non-content stuff, but the content is now a teeny bit on the small side.

    It looks like I can make the zoom site-specific though, so at least it won't affect other windows and tabs.

    This new look puts up a new notification (or whatever the jargon of the web software is) for each new post, rather than just listing which threads / topics have new stuff in. See screen capture.

    This can't be right, it doesn't tell us enough to be useful and is just sending duplicate information that wastes screen space.

    You mean the speech bubble and dot icons down the left hand side, Pete?  I have been trying to work out what purpose they serve myself.

    I'm sceptical how much matching actually happens with SCTs TBH

    Me too.  It may have happened at one time, but I'm unconvinced it would be viewed as worthwhile for ones made using modern production methods.

    I think it's highly unlikely that the OP's OTA is viable to repair.  If it isn't covered by insurance (or isn't worth claiming for) then I'd be tempted to mask off the damaged area (preferably with a curved edge to prevent diffraction spikes) and check collimation etc.  Assuming there's no other uncorrected damage it should be usable like that.

    I see no reason why the camera wouldn't work still.  Perhaps it could be connected up off the OTA to see if it's ok?

    My concern with the diagonal is that the mirror might have come loose.  If it isn't obviously damaged and doesn't rattle then I'd guess it's probably ok.

    Not sure about the focuser.  Is it a Crayford, or rack and pinion?  With a Crayford it's perhaps possible that any slack can be adjusted out as long as the spindle and mating face are not damaged.  I'd be concerned about possible damage to the teeth of an R&P focuser, but again if there's no obvious damage then a bit of adjustment might sort it out.

    Other than that it would be worth checking that the baffle tube is still correctly aligned with the secondary and hasn't bent.

  5. Ah, right.  I wasn't aware of that problem.  I guess it must affect mounts older than mine then.

    FLO have in the past had someone doing belt mods on the HEQ5 "while you wait" (at shows), I believe.  That might well just be on ones they're selling now though.  It could be worth dropping them an email to explain the situation and see if they are able to help in any case.  It may be that they can't, but there's no harm in asking...

  6. My garden is more slippery than an ice rink at the moment.  We have water standing on the ground even though we're on the side of a hill :(

    I did however actually see some stars last night, which must be the first time in at least a month.  I stepped outside the back door and looked up at Ursa Major almost directly above my head.  And my face was covered by rain :(

    I guess I should at least be grateful that "Storm Christoph" appears to have left us mostly alone.  The forecast was lots of yellow rain warnings and flooding, but we've not even had half an inch of rain so far this week.  Looking at the pictures on the news this morning others appear to have been hit pretty badly :(

  7. I don't know if the libraw(?) issue is fixed yet.  I must check on that.  I skipped on the previous Ubuntu release because of a dependency clash between different versions of libraw meaning that INDI won't co-exist nicely with other software that uses the standard system version of libraw.

  8. Not sure what you mean by "the older model".  Do you know roughly how old it is?

    I bought mine in early 2013 and it wasn't a major problem to modify.  Sadly since I did so the weather has been so awful that I've had very little chance to use it.

  9. Just checked with the ASI224MC that I happen to have on my desk at the moment.  It supports binning.

    To add to the confusion, the ASI SDK also allows for cameras to use "hardware binning" (which is also supported by my ASI224MC), possibly suggesting that OSC binning can be done in firmware on the camera or in the SDK if it is not supported or turned off in the camera.  I don't know if there's any guarantee that exactly the same process will be followed in each case so that the same data coming off the sensor would result in the same image being returned to the user regardless of the binning method used.

    Does that hold true for one shot colour CMOS/CCD too ? e.g. ZWO ASI183MC pro? (or any other zwo 'MC' for that matter).

    Some one-shot colour CMOS cameras do support "binning" and I'm pretty sure that ZWO's OSC cameras do, though it may be a process that happens in the driver software rather than on the camera itself.  I know there are interpretations of what binning means when you have an OSC image, but I'm far from certain that everyone agrees it means exactly the same thing.

    For example, if you requested a binned image from two different manufacturers cameras with the same mono sensor, I think you could be reasonably sure that the same process would take place in each instance.  If you requested a binned image from, say, an Altair camera and a ZWO camera with the same OSC sensor, could you be sure that the same process had taken place for both?  I'm really not sure.

    It may be the case that there's a single "most sensible" method for handling binning of OSC frames, but unless they show their working I'd not want to assume that all CMOS OSC camera manufacturers do that.

    Very nice. I was just watching Sherlock on Friday and a man was murdered because of his astronomical knowledge. He had a small reflector aimed at a skylight window. I had a hideous moment of self-awareness as I couldn't stop myself from talking over the episode to my less than interested partner. 

    Is that "The Great Game"?  An outstanding episode.
