  1. Hi Dave. Hanging my daughter's handbag from the centre will more than do the trick
  2. I could be wrong, but judging by the position of the great red spot, you took the video sometime soon after 7pm last night. Europa started a transit of Jupiter at 7.32pm and I think that could be the small bump on the left of your first image. Does the time sound about right? You captured some good detail there. I use these pages to look at GRS times and moon transits:- Transit Times of Jupiter's Great Red Spot - Planets - SkyandTelescope.com Jupiter's Moons
  3. I have a Lodestar and a QHY5 and the former is far more sensitive. For OAG you will always have less stars in the guide camera field of view and therefore it is best to get the most sensitive camera you can afford. I have not used the QHY5 with my OAG, but I have used both cameras on a guide scope, which is how I know about the sensitivity difference. I have used the Lodestar with the SX slim OAG and I never failed to find a guide star through my 1200mm reflector. the F/L gives a fairly narrow field of view and then the OAG pick up obviously reduces the star selection even more, but as I say, the Lodestar is up to the job.
  4. Well said. I agree, they are fantastic images and I thank Spanky for sharing them and his thoughts on his new purchase.
  5. The NEQ6 is a great mount. Have you looked at EQMod yet? I came across that in an article a couple of years back in Astronomy Now or Sky at Night. I'm so glad I did. It has revolutionised the way I use my mount and automated/simplified so many things and saved lots of set up time.
  6. If you mainly want to image and are concerned about wind then I would consider a refractor. Wider fields of view, easier to guide due to lower focal length, smaller, less cumbersome and less prone to moving about in a strong breeze. I use my 250PDS for planetary imaging (where wind is not a factor) and for imaging smaller DSO's i.e. M51. I use my refractor for anything else. Am I helping? I bet the answer is 'no' ;-) I think you will be hard pressed to find a better deal, within the price band you mentioned, than this First Light Optics - Skywatcher Evostar 100ED DS-Pro Outfit The focal reducer in the deal will give a flat field and nice round stars to the edges. It was a purchase I was so glad I made 3 months back. All but the image of Jupiter are with that kit and my (modded) 1000D Stargazers Lounge - drg35660's Album: The Learning Curve
  7. I haven't had first hand experience with an Equinox and focal reducer, but the link I posted it says "These new Skywatcher 0.85x focal reducers are optimised for the Skywatcher Evostar ED PRO (and equivalent Equinox) APO refractors." I guess nmoushon is best to check with his/her supplier.
  8. These are optimised for Equinox and Evostar scopes First Light Optics - Skywatcher Focal Reducers One end screws directly to the focuser tube and the other end screws on to the T adapter attached to your camera.
  9. Probably a focal reducer to give you a flatter field and round stars to the edges.
  10. From what I perceive - a quatro is just something trying to be a faster focal scope and has gofaster stripes and a bigger secondary mirror. Little is gained in back focus and that little is probably not required for imaging setups. - 190mn will take longer to cool down and may suffer more from dew. It is an expensive alternative to using a coma corrector and the aperture size is not great -I would go for a 200PDS, but anything will catch the wind..... and if it is crystal clear, it generally ain't windy - re-think the 250PDS
  11. My NEQ6 has lived in dry, draughty sheds for years. I stripped it down last year and it was as good as new and I didn't even need to do anything to it. I re-greased just to justify the fact that I'd bought the correct grease for the job and didn't want to see it go to waste.
  12. I've never even heard of a yoctometer! Thanks for posting.
  13. I guess so, but if you have a guide camera that has an ST4 guide port then I think you can do away with any connection between the mount and the pc. PHD allows you to choose an 'on camera' setting. This tells PHD the camera is directly connected to the mount using the ST4 ports and an ST4 cable. If you don't have a camera with an ST4 port then you can use EQMod to channel 'ascom pulse' guide settings from the pc to the mount. I use ST4 direct guiding and I also use EQMod (with Cartes du Ciel skychart) for the remote control functions it gives me, the easy and accurate star alignment and other features like GPS and accurate polar alignment..... oh, and I use an Xbox controller to manually control the scope.
  14. I use the EQDIR adapter, but I think you can use the handset - EQMOD. You would need a serial port on the laptop or I guess you could use a serial to USB adapter if no srial port is on your laptop. Having said that, the page I link has the following warning "PC-Direct mode is an undocumented feature of the Synscan handcontroller that many people have found to work successfully in combination with EQMOD. However you should be aware that the EQMOD developers have no technical insight into its implementation or of its limitations. We cannot therefore guarantee reliable operation when using PC-Direct mode and this fact may limit its practical use to evaluation only. We would advise strongly against unattended operation whilst using PC-Direct Mode." Play safe and get a EQDIR :-)
  15. I use Win7/XP remote desktop connections to control the astro laptop from the warm indoors. More recently, I set up an incoming vpn connection on my Win7 pc indoors and now I can connect to it with my iphone and check up on, and control the astro laptop........ from my local pub :-) Happy days!
  16. I guess you slept all day with a big grin on your face. Good work!
  17. What is a hobby to me is a business and a living to my suppliers. As I said before, in the thread that prompted this one, I think they work very hard to keep us lot supplied. We have a good choice of suppliers for most items and then there are some 'niche' items that only one or two suppliers will have and we may just have to be patient to get our hands on such things. There is a reason why Primark, etc don't sell astro gear and that is 'demand'.
  18. Regarding parts, Optical Vision Ltd would be the people to call, but hopefully you won't need to :-) You may be best to speak with a SW dealer/stockist (FLO is one), because the OVL website states "We are unable to respond to queries of a technical nature from the general public, please contact your nearest dealer/stockist for this assistance"
  19. I'd agree with themos. If polaris stays under the + when you rotate the RA axis, then your polarscope is aligned with the mechanical RA axis. Aligning the polarscope is relatively easy and straight forward, so you could always align if you are in doubt. I think that it will be the same on an EQ5, but these are instructions for the EQ6 http://ca.skywatcher.com/upfiles/en_download_caty01316546640.pdf
