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/

With reluctance I am looking to sell my 200mm aperture f5 Helios Newtonian OTA. (Helios is a brand that became incorporated into Skywatcher - this closely resembles Skywatcher OTAs)
The Helios is offered with single speed rack & pinion focuser, tube rings, 22 to 1.25" adaptor, dovetail bar and grab handle for £90 o.n.o. In good condition except that the dovetail bar appears to be discoloured by exposure to sunlight.
I have not used the telescope for many months and with a persistent problem in my right arm my enthusiasm for moving heavy kit around has diminished.
Buyer to collect from North Bucks.
Offered as option with the OTA: EQ5 mount with RA drive + 6 volt sealed lead-acid battery +charger + standard and extra long Dec slow motion manual shafts. £150. Condition - used but working.
If I sell the OTA I will be looking to dispose of its accessories:
9x50 Skywatcher straight finder - in excellent condition except that the small plastic dust cap is missing.
Cheshire collimator, boxed, as new.
Helical fine focuser, range 10mm, ID 1.25", screws into 2"adapter.
3x Datysun Barlow, as new, boxed.
Widefield eyepiece, 22mm f.l., 30mm body (note not 1.25") with built in focus, works well with this telescope.
Plastic collimation cap (no cost).
This bundle would cost around £114 new - offered if bought with scope at £75 o.n.o.
I'm super happy to have found this forum of night sky enthusiasts and look forward to learning and sharing on this site! I am an amateur stargazer fortunate to live in a rural area with great dark skies. I'm used to using a GoTo Celestron.
Unfortunately I'm having a problem with a newly purchased Orion SkyQuest XTg 10.
I've only used it a couple of times. Recently, when I turn on the power, the hand controller (a SynScan V4 GoTo, version 04.39.04) states a message "Both axes...no response!" which means the motors won't work.
I've unplugged all the cords & replugged to no avail. The power comes from a new Orion Dynamo Pro, 12 V, Lithium Power Supply which was recommended.
Does anyone have any ideas what the problem might be?
Thank you 🌟
Hello to all!
Posting a photograph of the Summer Milky Way band that I took last week.
However, I do not know how should I feel about this!
This is when the band was right overhead, which is a rare sight for us and happens only when monsoon season is delayed. There was decent glow towards horizon but literally nothing at zenith.
19 degrees north latitude, around Bortle 3 level sky, taken using Nikon 5300, basic lens.
And with this, I prepare to have no view of stars till September ends
