I've had a reflector telescope for years but never really used it (this one) . I've recently dusted it off and decided to try my hand at astrophotography.
I was really pleased with myself when I successfully pointed the telescope at Saturn and could make out the planet and rings (it looked like one big white ring but a good start). Once I'd nailed getting the planet in view I decided to hook up my Canon EOS 600D.
Initially I connected it using THIS and was able to get a picture of a Saturn and ring shaped slightly blurry blob, which I have to zoom in on the image to see, thus blurring it further. For my first attempt I was pretty pleased. I then watched some YouTube videos of people showing how it's done and upgraded the Canon T-ring to THIS so I could drop a lens into it for more zoom.
However, when I try the new adapter with a lens the camera picks nothing up - any picture I take regardless of how long exposure I use just comes out as a black screen - not even any stars.
If I take then lens out of the adapter I get the same. I only get a picture if I use the original T-ring, back to the blurry really small blob.
Does anyone know what I'm doing wrong? I'd really like to get into astrophotography but not getting anywhere yet.
Many thanks in advance.
I only have room in my life for one lovely refractor, so one must go. I have acquired a Takahashi, so my beloved and well cared for William Optics Zenithstar SD66 has to go. It is optically perfect with no scuffs or scrapes. Has been used as a guide scope and astrograph on my LX90. It comes in its aluminum flight case. OTA only.
Price is £280 or 325 euros, to include postage within the EU.
PM me if interested.
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/

Further to my post about the Skywatcher flexible 130 p, I am now looking at a short focus tefractor. I am 70 years old so can only manage to carry a fairly lightweight telescope into my back garden.
I am interested in viewing the moon, double stars, bright planets and the brighter star clusters.
I am looking to purchase one of the following
Celestron travel scope 70
Bresse r Classic 70/350
Skywatcher mercury 705 70mms.
I understand that these telescopes have limitations, but they the only ones in my price range.
Any comments or advice would be welcome.
I have a quick question. I am thinking (very loosely) about the possibility of a small APO for wide field views to piggyback on my CPC 1100. I am interested in recommendations. At the moment I am not planning on AP.
I can see that there is a huge range in prices and to be honest I am looking for something thats reasonably decent quality (circa £500 - having no experience with APOs I really don't have a sense as to whether thats quite enough or not really enough). I had looked at the Orion Carbon Fibre 80mm f/6 APO Triplet but its just a bit too much money.
And many thanks.
