Hi, I'm keen to buy a small good quality refractor primarily for astrophotography of galaxies and nebulae. I'd like to use my Pentax K1 full frame DSLR with the telescope.
Reviewing YouTube & Google the; Altair Astro 72 EDF deluxe & William Optics 71GT look like they might be good models to go for. I'd welcome the community's views on both, and any other alternatives people recommend.
IAS 2019 Review - Friday 15 November
My second show (first was last year), as before got there on Friday 15th, soon after 0900hrs.
Despite the weather, seemed to be fairly busy in the main hall. Had a few good discussions with different vendors, 365 Astronomy in particular. Even the guy on the Vixen stand near the entrance, remembered me from last year!
RVO had a whole hall to themselves, not really sure why? They did seem a bit 'lost' in there. All that space and not much kit...
Again, there to 'window shop' only, but still managed to spend £90! Got a good price on a WO 1.25" Dura-Bright Dielectric diagonal.
(Thanks Widescreen) Best online price I'd found, prior to the show, was about £100 inc. postage/delivery, so saved a tenner!
Restaurant was a big improvement over last year. Coffee was OK, lunch was pretty good too. Choice of Fish 'n' Chips or Cottage Pie.
All gone by 1345hrs...
All in all a good day. Looking ahead to 2020, might make three in a row!

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 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/
Aperture: 105mm Apochromatic Precision Triplet Focuser: 3" Dual Speed Focuser with 2" and 1.25" eye piece adapters F Ratio: f/7 Focal Length: 735mm Color Correction: Excellent Minimum Tube Length: 16" in travel mode Tube Diameter: ~ 4-1/8" (105mm) Dew Shield Diameter: ~ 5-3/8" (137mm) OTA Weight: ~12lbs (5.4kg) Retractable Dewshield: Yes
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.
