  1. Hello and welcome. The Dobsonian's are an excellent telescope being very easy to use more or less straight out of the box. They can be heavy (why I stopped using mine) and are large to store but if you are keeping it in your garage you have the best of all worlds in that it's close to where your setup is and it's already acclimatised. Enjoy

    Greetings

    Hello and welcome. Not jealous of where you live...... honest A few years ago we had a break in mid Wales; knowing it to be a dark area I loaded the car with my 200P and lots of bubble wrap. We were fortunate enough to have some very dark and very clear nights when we were there. Didn't bother with the telescope, just sat outside and looked. First and only time I have seen the milky way. The 200P is an excellent, very easy to use and enhance telescope but not very portable. If you have thought about taking your telescope with you for when you blank at your other hobby you may want to consider something a little more portable, if on the other hand the telescope is staying at home, then an 8" Dobsonian is a great choice. Enjoy

    Hi all...

    Welcome and good choice on the Heritage, looks a great starter choice Another +1 for turn left at Orion, it will not only give you more than a few pointers to look at but it also gives you some calculations for eyepieces and telescope maths. I must admit I found the book a difficult read initially, but you learn and understand it's content as you go on and then the book becomes very useful. I also find a planisphere very useful for spotting the brighter stars very quickly helping you find your way around. And saying telescope.... does that make me uncool? Oh yeah.... that's cool
  4. Look at that bad boy raised the OTA 16" and will now clear the fence, giving me the opportunity to at least try and get a few pictures of the conjunction. As you can see, I have a very small window of opportunity but hey, you have to try Its an interesting fit in that you could end up with it out of alignment with the North leg of the tripod but if you put a mark on the mount and the tripod, install the extension tube, then just line the two marks up and away you go. Also have to say that it makes leveling the mount an absolute doddle. By placing a bubble on the extension tube you can very quickly level it up.
  5. I was just taking pictures of the moon and planets as far as I could so didn't really try with DSO other than double stars. You can use the FLO field of view calculator and play with different set ups using your telescope to see what you can achieve only problem is it will definitely add stuff to your Christmas wish list
  6. As others have mentioned, I had a 200P for a number of years and bolted a Canon DSLR to it using a Barlow, don't recall having any problems other than how fast everything moves. Enjoy
  7. Hello Mohib, if the clutches are locked so you can't reposition the mount by hand and you can hear the mount driving, it could be driving at such a slow speed that you may not notice it. Ramp the speed up using the controller and see what happens. Hope it helps.
  8. And so it begins who needs money anyway I tried afocal photography initially and couldn't get on with it, so I moved to a DSLR. I bought a used unmodified Canon EOS 100D primarily because of the weight of the body, its about as light as they come. It's an old unit now so there are likely to be newer and better models with a similar weight out there, have a look around and see what you can find. Enjoy Agree with nephilim, once you get into it you will realise how fast everything moves so it will take some practice on a manual mount but single shot pictures and getting the best out of your camera and telescope are part of things I enjoy about this hobby. A tracking mount will most certainly help in both observing and astrophotography
  9. I am also unfamiliar with the 6SE having a MAK180 but the two are similar and I have been playing with a focal reducer on that. According to the book of words, to achieve the stated focal reduction, the focal reducer should be installed at the visual back. I would guess that without a Crayford focuser the VB on a 6SE is the same as on the MAK and the FR is fitted into the VB adapter. You then need 105mm between the FR and the EP to get the full focal reduction. I would suggest that if you have a Crayford focuser fitted, the FR should go before the focuser, but that is a just a guess. On mine, with the FR fitted at the VB, after focusing, bang slap in the middle was a huge great secondary mirror making the thing a waste of time. However, by continuing to play and fitting the FR at different positions, and using different spacing's you can still get focus and the secondary disappears. The best I found was to fit the FR to the EP, what the actual focal reduction was I have no idea but it was still significant. Hope it helps.
  10. Hello and welcome, you will find answers to all your questions here I am sure..... however..... that question has some very interesting answers that I really don't understand. There is a very similar and recent thread on here that you may wish to search out, it has answered the question using words like radians, pixels etc, so my version of the answer to the question is that you don't get magnification from a camera, you are taking a picture. Enjoy
  11. +1 for sky at night magazine. And maybe consider a planisphere? Not a book but will help you find your way around the night sky.
  12. First off, I can't believe that something of that value does not provide storage solutions. Hey ho, the world we live in I suppose. I don't have that telescope but it looks like the mount and OTA has a similar arrangement for attaching to the tripod which is by means of a long bolt that you tighten through the tray? If so, is it possible for you to put that bolt or a similar threaded bolt through your sturdy table and fix the mount in position on the table and as such keep the OTA in a balanced position on the mount?
  13. I was talking to my son the other day about the sad but true point that I found the maths around eyepieces to be interesting. He then admitted a sad fact from his childhood (he is now 38). He loved a Japanese anime programme called Dragonball Z. In it, the character's came from a planet called Namek. The story goes that they used an a space ship to travel to Jupiter from earth which took 57 seconds. He calculated that the ship was travelling at between 34-56x speed of light. They then traveled to the planet Namek taking 37 days. This puts the planet Namek at between 3.49 and 5.74 lightyears away. The planet Namek has 3 stars, one being a Red Dwarf. Turns out that Alpha Centauri is in that distance range, Proxima Centauri is a red dwarf and there has been a planet found called alpha centauri B in the habitable zone. The cartoon Dragonball Z started 26/4/1989 and the planet alpha centauri B was discovered 24/8/2016. What do you reckon? Disclaimer: These numbers and all information are all my sons work
  14. Great topic For me, seeing my first double star, Achird, seeing and getting a picture of a phase of Venus, talk about grin
  15. My first "proper scope" was a 200P. Get a good app for the phone, take your Dob outside, plonk it down where you can see the object of your choice , line it up and away you go Probably the most important thing is to get the finder scope lined up as close as you can get it, you can do that at anytime during the day so clear skies not needed. Pick the furthest object you can see to line it up and try and leave the finder in position when you put it all away. If you are a clutz like me, you will knock the finder scope but do try not to. You don't have to worry too much about dew, if you can, leave your Dob safe in a shed, that way temperature won't be too much of a problem either. You will be surprised at how fast things move, so the clutch and bolt torque will give you a learning curve. I couldn't get on with the phone holders so didn't really try too hard at afocal photography but its well worth a go as I did get a few "lucky" shots, so that will dip your toe in the astrophotography field or there are all sorts of adapters for your DLSR. Enjoy
