  1. Good to know you don't read responses...
  2. Yes... please what ever you do, do not attach a dew heater straight to 220V... it will light up faster than you think and possibly star a fire. You will need to use a power converter 220 VAC to 12 VDC, like this one: http://www.meanwell.com/webapp/product/search.aspx?prod=HEP-100 may others are available. the same goes for all astro equipment. 12-13,8 V is the range you need to use. The above converter for example is 8 Amps, which is normally enough for all your stuff. If in imaging, you may want to use a separate converter for your camera's. The cigarette lighter plugs are plain out worthless, but they are very easy to replace with normal 12 v plugs like RCA, banana plugs, 5,5/2,1 mm plugs or 3,5 mm jacks. A little soldering skill is useful, but learned in a few sessions. Dew heater controllers are very easy to find on Google also: http://www.kendrickastro.com/
  3. 7331 and stephan's

    'Almost' convinced? It is a fact that more integration time reveals more details with less noise. I've seen 36 hours integration time on M31, one of the brightest DSO's in the sky. Totally mindblowing!
  4. This is a very nice tripod for the Star Advenurer, but I understand it is above what you want to spend https://www.berlebach.de/?bereich=details&id=439&sprache=english I find it is incredible stable and it does a great job. Very nice combo.
  5. Did you try to not use the mirror lock? Not necessary with longer exposures. The little tremble of the mirror is too short to make a difference.
  6. USB control for Atik efw1

    Halfway down the page you will find the drivers for the EFW1: https://www.atik-cameras.com/downloads/ Maybe this is of any help?
  7. Probably you are too far out of focus to pick up stars. Lesson learned: don't walk away or leave your equipment unprotected if you are not 100% sure it won't rain. As has been said above: dew, no so much of a problem. Rain is a killer... These: http://www.scopestuff.com/ss_t365.htm are top quality covers. Put a little heater underneath to prevent dew and do not totally close them at the bottom, so they can ventilate a bit. To prevent electrical problems, you can spray all electronics, boards and connectors with NanoProtech Electric spray. You will have to take things apart a bit, to be able to spray the boards on both sides, but it really makes a difference.
  8. yes... there are so many options... it's confusing sometimes. You can also use a webcam on your standard guidescope, that will be less then 100. Not working as well, but working.
  9. Have a look at the Lacerta Mgen autoguider as well. Not cheap, but good. basically the small screen is just for setting things up and find a star. The camera that comes with it is very sensitive. After that the autoguider does it's job. When using a DLRS you do not need a laptop... and power for it... As a powertank for an autoguider and the Star Adventurer the 'new' Celestron powertank with LiFePO4 batteries is very usefull: https://www.celestron.com/products/powertank-lithium
  10. That is the smartest thing you can do at the moment. And do not expect you will be able to make 'nice' pictures right away. AP is a steep learning curve and a lot of pitfalls are on your way. Patience and perseverance are the tools necessary for result. Good luck and I hope you will make some satisfying pictures!
  11. I think you are on the right track! Be aware the Star adventurer only tracks on RA, so you need a very good polar alignment to do 'longer' subs. The shorter the focal length of the used lens or scope the longer your subs can be. It is all about trial and error, but with a little experience you will do fine.

  13. The screws on the side are to give you an opportunity to find guide stars where the one you like can not. The Orion comes with a set of adapters, that makes it very flexible for any use you can think of. It is really the most versatile OAG I have ever seen, and I have seen quite a few. But of course the choice is yours...:-) And owning one I can tell you the build quality and looks are top. No play anywhere.
  14. Yes exactly. This not the AOG that I meant, but the principle is the same. The Orion TOAG has more sofisticated option for adjustment. You will be happy with it, I think.
