Skywatcher 80 ED DS-Pro outfit including matched flattener and motor focus £550
This kit gives you a great introduction to astronomy and imaging, which is why it's so popular. You can see details over at FLO but there is:
80 ED Ds-Pro OTA (Objective Lens Diameter: 80mm, Telescope Focal Length: 600mm, f/7.5)
SW Eyepiece (2"): 28mm
2”/50.8mm Di-Electric Star Diagonal
Dual-Speed 11:1 2” Crayford Focuser (Backlash-Free)
Supplied with Tube Rings & Mounting Plate - please note there is a longer black vixen type dovetail fitted, not the fancy new green short one you will see on the FLO site

Aluminium Carrying / Shipping Case
The RRP is over £720, so grab a bargain while you can.

Hi to everyone, I used to do some astrophotography in the past with a Celestron AVX and DSLR but after few month had to give up for several reasons, including light pollution (I'm living in zone 3 east London), and also working shifts. Now I want to start again, and this time more serious. I've been searching around for a couple of months to choose all the gear and I'm quite happy with the list so far although it's a bit over the price I planned at first.
I will get an William optics Z73 with his 50mm guide scope, a flattener/reducer 0.8, light pollution filter IDAS D2 and as camera I will use a Canon 600D modded and I will buy a ZWO 183MC Pro, after so much research, I'm very happy with the scale and framing I will get with this combo, but I'm starting to get confused with the mount.
My first idea was to go for an HEQ5 Pro, as my previous experience with the AVX has been awful, then I realized that the FLO, sells that mount with belt modification and also some cleaning and tuning if required, I heard that it's a big improvement over the stock one and the price it's ok, but another important factor for me it's portability. Unfortunately, my garden doesn't allow me to do much so I will need to carry around on trolley, for a km walk, I'm a strong person and been doing plenty of time with the AVX, so my confusion came recently when the iOptron mounts entered my radar. I start comparing the heq5 pro with belt, with the iOptron cem25EC and the CEM40 without encoders, and I'm so unsure of which to buy, the cem25 seem to be the equivalent of heq5 at least speaking of payload, but in some threads I read people saying it's a bit fragile so kind of remove it from the equation although the weight it's interesting for my situation, then the cem40, seem to be quite similar on weight to the heq5 but with higher payload and that's interesting too as I will buy a C11 at some point.
Now it will all come down to the accuracy of tracking I guess, how the heq5 and cem40 would compare on tracking and guiding? If the cem40 it's better, I would probably go with that since it holds more and would last longer as I don't plan to get anything bigger than a C11, but if the skywatcher it's better, I could decide to go for that, and when I move to a place with better garden then get a second mount with higher payload.
Apologise for the long post and my english.
Hello, this is my first attempt on NGC 7635 with my skywatcher 250pds on an NEQ6 synscan mount. These are 7min subs stacked to a total exposure of 5 hours taken with my unmodified canon 700d and a skytech cls filter. No coma corrector was used as I haven't gotten one yet. I'm just wondering how I could make my images look clearer when zoomed in and improve them overall as I can see the image gets more blurry when I zoom in onto the bubble, should I use a higher magnification? Do I need to take more darks to get rid of the redness around the image ? Or perhaps I stretched the image too much in Photoshop? I used 10 darks, 60 bias and 60 flat frames.
Update: I have now further processed my image with greater care and got a much better result.
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.
