Sunday 30th June.
NLCs started appearing as the skies cleared around 1.45am.
Grabbed gear and headed off around 2.15am to the same location as last two sessions. Another 90 shots taken!

Clicking the pictures should open the hi-res images.

The other night, I got a rather weird thing happen using Sharpcap. In live-stacking, the first image arrived and it was full of stars. So, without changing any settings, I did a "platesolve" (which also realigns the scope) to centralise my target. It did its single frame capture and I got a practically blank screen and a message saying it could only detect 3 stars. I tried reducing the "sigma" setting, as advised by the on-screen message, with little effect. What gets me is that the same settings produced a whole mass of stars in each of the subs that were being live-stacked. Never had this happen to me before, and no, of course I didn't do anything intelligent like saving the log file!
I can always try to replicate this next time (although I always find trying to replicate something that isn't working to be a weird activity in itself!), but on the off-chance that anyone can see what was happening without the log file, I thought I would ask.
I am wanting (not really 😪) to sell my Stellarvue SV105-3SV with tube rings [not shown in pictures]. The telescope is in great condition with very little dust and no scratches. There is one very small ding in the dew shield paint but it is not dented and it is almost not even noticeable. It happened when I took the telescope out of the saddle and it lightly hit the saddle. The telescope has never been dropped or had any issues and is optically perfect with a strehl of .95 or higher (claimed by Stellarvue).
I've only used this telescope for imaging however I've once or twice thrown an eyepiece in it during a star party or two and it's VERY crisp with no false color.
Currently I live in Italy so that's where it can be picked up or shipped from. Price is negotiable however Stellarvue says it is worth around $1200-$1500 USD. The nice thing is you wouldn't have any VAT from Stellarvue . Please let me know if you have any questions, comments or are interested.
Lastly, here is a link to some images that I've taken with it and what it looks like mounted up: https://www.astrobin.com/users/chriscorkill/

I have a question about filterwheels; SBIG filter wheels specifically. As far as I know they are the only ones that really use the 8 position filter wheels. So I have it loaded with L, R, G, B, Ha, OIII, and SII. So that is seven filters, what goes in the 8th slot???
Thank you for your insight,
