  1. Park your scope before switching off and changing battery. Switch back on and it should retain all settings.
  2. Thanks all. Think a trip to Lingfield Saturday then :-)
  3. Anybody had experience with one of these? Slightly cheaper than the Skywatcher and with a built in cooling fan on the 8".
  4. Thinking of joining the Dobson Brigade. This is because half the time from my location I can't 3-star align my Skywatcher Mak as I can't see the guide stars in different parts of the sky. Also because of what my fiancee said the other night to me "It's a clear night just a shame the scope takes so long to set up" This has has me looking at scopes to plonk outside the door and push around the sky. Budget for scope is £300 plus I'll buy a laser collimator as an extra. So should I buy the Skywatcher 200 Dob or the same size Explore Scientific one? Bearing in mind the price difference is only a few pounds.
  5. I can do 2 star and 3 star no problem from a dark site. Its just my location that lets the alignment procedure down. Thats why I've been thinking about the Dob for a quick nudge round the sky and leave the Mak for dark sites.

  7. Need it quite mobile for where I live Olly. weight not too much of a problem tho as I'm over 6ft tall.
  8. Budget was around £1500 overall for setup. I've seen the remotes for the camera on Amazon cheap enough and programmable. Might get a biggish newt and then buy the frac later on because at least then I have a good mount. I'm used tobthe synscan handset as I have the Skywatcher 127 goto mak.
  9. Thanks for the info guys. AP will be purely deep sky with it as I have a mak for planets and the moon. Will be photographing galaxies, nebulae, clusters etc.
  10. Thought a Newt would be better as generally they are around f5. I'll probably need a field flattener and a collimation tool of some sort. Never had a Newt before but collimation can't be that hard as I'm mechanically minded.
  11. Interesting website. I'll do some more research as I like the idea of something for both visual and ap. Might have a look at a newt.
  12. Was looking at one of the Celestron Edge SCT's or won't that be any good as I understand that a lot of people use them for imaging. My interest is in large DSO's such as M42 etc.
  13. Ioptron zeq25 + ED80. Very light mount with good payload, built in gps and 59k database.
  14. Looking at an AP setup for my DSLR. Was going to go for the iOptron ZEQ25 and a frac. Looking around I am thinking maybe it better for me to buy a bigger scope for visual as well as AP. Any suggestions?
  15. Total rig weight will be very low. I'll be using my Nikon D5100 DSLR as I won't use my MacBook. I have looked at the iOptron ZEQ25 GT and it looks like a very capable mount. Then I'll just have to worry about what ED to put onto it. I had browsed the Explore Scientific Triplets as they seem good value for money but don't know anyone who has one. Not seen any images taken through one either. Always thought bigger is better aperture wise but that is only for visual use isn't it? Just thought the 8" newt would give better images as its much bigger than an ED refractor.
  16. I'm currently saving up for an Astrophotography setup. I've been looking into mount/scope combo's. I know the best way is to get an ED refractor with a focal reducer but I've also been looking at the Celestron AVX scopes. The 8" newtonian on the AVX mount is offered at a reasonable price. It's an f5 so is plently fast enough for me. Was thinking of getting this to start out as my 127 Mak is too slow for DSO's and has the wrong mount for long subs. I could then use the mount for an ED I the future when I've got some more money together. The mount is big enough for what I want and portable enough. I will then also have a bigger scope for obs too. Someone suggested to me to buy the iOptron ZEQ25 GT for portability with WO71 GT or equivalent on it. I do travel a bit so want it portable but don't need it that pertable for any airline travel, just so it can fit in the car with luggage for weekends in Scotland etc. Any further suggestions I've not thought of?
  17. I have a Skywatcher 127 Mak on the Alt/Az Synscan Goto mount. Fantastic scope for Lunar and Planetary obs as well as picking out doubles/galaxies/open clusters etc. I've done some AP through it with excellent results too. Cracking little scope and always a pleasure to use. Highly portable too. I brought ours back from Cyprus as hand luggage, mount and all.
  18. An Alt/Az will still need to be aligned with a leg of the tripod pointing north and the scope 'home position' aligned to north. I.E. Scope tube pointing north and level. The SLT is basically the same as my Skywatcher 127, mount, hand controller etc. If it isn't pointed north, levelled and aligned correctly with all the correct info in the hand controller it will drift off and not be able to find anything and centre it in the eyepiece. This will be critical for AP especially through a long focal length Mak. I always use 2 star alignment with mine and periodically realign during obs and AP sessions. I use a D5100 and I can focus with 'live view'. Just ramp up the ISO to max, align and focus, then put the ISO back down to what you want. HTH.
  19. You also can't go wrong with a copy of Turn Left At Orion.
  20. Thats the same in the UK, formthe price of the mount on its own you can get a C6N on it cheaper in some places. I'll be getting one for an ED80. Will buy the scope/mount combo and just sell the ota to help finance an expensive ED.
  21. Friday night at WA was a waste of time as sea fog rolled in and obscured the sky by around 8.30pm. Last night was much better with around 25 scopes plus a lot of public turned out, a fantastic evening had by all. Next event we are holding is on Sunday16th March at 8.00pm at Splash Point near the pier on the seafront. This isnthe double transit event of Io and Gannymede crossing the face of Jupiter.
  22. The dobs focal ratio will be far lower than the SCT so will be much faster. This will give better, brighter images and better contrast.
  23. Absolute bargain! Go bid on it! I had an old Celestron C9.25 years ago when they fisrt came out on an EQ mount and the optics were superb. this scope is from the same era and will be excellent. Even if it cost you £200 to get it cleaned professionally it will still be an excellent scope. Stick it on an HEQ6 and it'll be all the scope you'll ever want and more.
  24. Buy a very good book called Turn Left At Orion. This will teach you how to navigate the night sky by star hopping. It also shows you what you expect to see through a scope etc. It will soon teach you how to navigate the sky.
