Solar Autoguiding with PHD2.
I've just seen over on FB a new extension to PHD2 that facilitates both Solar and Lunar autoguiding. I know some folk are scared of FB but it's the only place I've seen mention of it thus far , and it's a Private group so it's not full of the usual FB types. https://www.facebook.com/groups/132078120...

Re: 27th Feb That large sunspot
Very nice work John. I like the Ha images but for me nothing beats a 540nm filter for a fine photosphere view of AR13590. James Us poor 'whitelight' folks have certainly seen the best of this region I think , and all the big'uns for that matter ... :P That's ignoring the occasional X-class flare of...

Re: Routine pressure release in Lunt etalon
No experience here but I'd assume the weather would affect things to a degree , there being routine differences in atmospheric pressure hence why we use barometers ?

The filter is indeed an Altair 393-3 nm (and not an Antlia 393-3 nm). I guess Altair will soon provide information.
So it's a new , "soon to be announced" product then ?

No 2" on the website and when I spoke to them about a 2" they said it would be too expensive and low demand would make it a non-starter ...
