Not strictly astro-gear but I took a look at the rules and didn't see any restrictions.
If this is a problem please just let me know, or remove it.

Northbridge plastic retaining clips are a known point of failure on 4,1/5,1 Mac Pros.
This one had the clips replaced with metal nuts + bolts before there was any problem.
Custom fan curves always kept NB temps at 50 or below.
I've just been reading through the thread about scammers etc.
Perhaps I should have said while my post-count here is low, I've used the same name online for many years,
and am long-time admin of a pretty popular forum.
I'm not going to advertise that here but if anyone's interested in this machine I can send some links for character reference.
I also have 100% on ebay (800+) and would be happy exchange messages from my account, for confirmation.
Over the winter I got into playing with a phone mount on my telescope eyepiece and got some pictures of the moon... But not much else as there are always limitations on what a phone camera can do (and how well I can align the camera to the eyepiece).
If I was to upgrade to a camera to mount onto my scope, what should I be looking for? I have been tempted to give it a go with whatever I can find on ebay or similar, but don't want to buy something only to discover that it's lacking something important. The only thing I know to look for at the moment is to make sure there is a suitable mounting ring for the camera (a T ring I believe they're called).
My targets will probably be: Orion nebular, Jupiter and Saturn to start with. This is purely because these are targets I know I can find.
Scope: Skywatcher Explorer 130P (650mm focal length, 130mm diameter)
For sale 450D camera modified for astronomy, the IR filter has been removed to allow the important red emission nebula to come through. The price is £140.
This camera has a very low shutter count of 1588, in very good condition, comes with 1 battery and charger (connects via USB to computer or smart phone socket ect ), I don't have the original box, but will pack, very well. The price includes special delivery. This is for the camera body, no lens. Any questions please email me any questions......clear skys.
I've just had a Canon EOS 250d modified by Juan, IR filter off and shim to restore focal plane. He previously did the same for a 100d which got me going in the hobby. Juan is willing and able to take on successive generations of camera. I prefer to rely on Juan's experience for this task, despite me being an optics specialist professionally. The cost of the camera and Juan's conversion service together are a bargain and I trust him with a new camera.
I like to use this type of imager over the specialist cameras because they are the result of Canon's massive R&D capability and bundle together all these functions: battery, an up to date sensor chip, the on-board software, on-board storage, built-in display, easy-fit Astronomik filter. In the case of the 250d, that very important tiltable display so you don't have to crawl around on the wet lawn to see it. The only thing they don't have is an easily-implemented thermo-electric cooling. But I've got a long way to go in astro-imaging before I care about noise that much (though I'd like to cool, and understand what can be achieved, I use stacking averaging in the meantime to go part way in that respect).
The dslr is my one imager for three rigs, the most notable being that it's lightweight enough to go on my Omegon clockwork mount.
On my heftier rig, I do have an Altair camera with a Sony back-lit chip but only use it for tracking with a wireless-controlled Stellarmate setup, having got fed up with all the cables and tablet pc with memory dangling off it.
Not sure which section to put this in? getting started or cameras, (Mods please move if necessary)
Need a little help/advice/recommendations,
I have been away from my telescope/astrophotography for about 2 maybe 3 years, i kind of lost the mojo for it, but now looking to get back to it, So i'm looking for camera advice/help,
Previously i only ever used a DSLR for astrophotography, however i am thinking do i stick with that or do i get something different? I know there will be a learning curve with new camera setup,
My area of interest is/would be Nebulae and Galaxies,i know there is no one camera fits all kind of thing, so Nebulae would be my main interest with Galaxies coming 2nd.
My current scope is the (Older Blue Model) Sky-Watcher Evostar 80 DS-PRO ED, so with that in mind what would be a good camera to pair that with, colour or mono i'm not fussed really,
My budget for new/2nd hand camera is £700 but could maybe stretch to £800.
Any help/advice (good or bad) will be greatly appreciated.
