  1. I had similar last year. At one point I was actually finding excuses (however tenuous) why I couldn't or shouldn't get set up .......... thankfully I now have my astro-mojo back, just in time for endless cloud If it keeps up much longer I'll have to get my SDR meteor detector up and running again.
  2. 050517 - Moon

    Thanks. Scope and camera were on my tripod and a the wind messed up a few shots. Used the 750D's LiveView 10x zoom to check focus.
  3. 050517 - Moon

    The Moon from last night, just before the clouds rolled in (again!) SW Equinox 80 Pro & EOS 750D. Single image - 1/200sec - ISO100 - No processing (cropped & resized for posting).
  4. My Starsense HC did lock up a few times when I first got it ...... always when the scope was pointing almost straight up. I tried a User Auto Align (pg13 of the manual) and that seemed to work. No idea why but I've not had any lock ups since doing that. If it had been pointing towards the West when it locked then I could perhaps understand (house!) but it was always pointing up high towards the zenith.
  5. Good to know. Glad you got it sorted in the end. However .... Do you seriously expect us to believe you've had 3 hours of good clear skies
  6. I got the same advice from Celestron. I installed the PL2303 driver from the link they sent me ( http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=225&pcid=41 ). I already had the same driver/version installed, but I guess reinstalling is never a bad thing ...... other than my 'note' at the bottom of this post! The issue I had was that I didn't have the ASCOM Celestron Unified driver installed ( http://www.ascom-standards.org/Downloads/ScopeDrivers.htm ). Then in the ASCOM settings I select 'Celestron Telescope Driver' and it all seems to connect up OK. Now I think about it using that driver makes sense (being a Celestron HC) My cables go PC -> SS HC then as normal to the Interface box. There is no need for any other setting on the HC, so no equivalent of the SW 'PC Direct' mode. So far I've only controlled things with my laptop close to the mount, so no long/active usb cables etc, but that is something I need to do. Note: All of this was about 10 days ago .... since then my laptop died and needed all the software (incl Win) reinstalling ... so now it's all back I've got to connect up again and see if it still works!
  7. Best security - Little is more

    Well maybe not for a garden rake, but shed break-ins are not that unusual as they often contain power tools, bikes etc. in fact shed break ins happen is spates in certain areas. Most local police force websites contain gardedn/garage/shed security advice. This link from Nottinghamshire Police https://www.nottinghamshire.police.uk/advice/prevention/shed Has advice and a PDF on securing your shed (or discreet obs!). And this from Essex Police on securing your garden in general https://www.essex.police.uk/advice/garden-security/ Fitting an alarm doesn't cost much http://www.homebase.co.uk/en/homebaseuk/yale-shed-and-garage-alarm-210437 Your neighbours may ignore an alarm going off, but I'm sure you wouldn't :-) either way I'm sure the scumbag breaking in won't hang around! The PIR should trigger the alarm as soon as the door moves. CCTV might be going a bit too far, I'm lucky as I have an old CCTV system from our shop and have put a cam looking over our back garden, might not (probably not!) going to get a face image, but it will give a date/time and general description.
  8. Ok thanks. I've managed to get things working (mostly!). The laptop connects direct to the usb on the bottom of the Starsense HC .... the problem wasn't the HC it was me stuck in 'Skywatcher' mode. What I hadn't done was install the ASCOM Celestron driver as soon as I did that things looked much better. I think put a bit off course with the driver issue because I got Stellarium to see the mount and control it even without the Celestron driver, so assumed all was OK! So I have Stellarium, CdC, Astroplanner and BYE all talking to the mount and controlling it through the SSA for Skywatcher HC. So it should be easy enough to align with the SSA and then swap over to the laptop for imaging. The only issue I still seem to have is with PHD2 - as soon as I try to connect to the scope it crashes as soon as the mount control window opens, hopefully I'll get that sorted before the next clear night.
  9. I'm currently using a Starsense for Skywatcher on my HEQ5 Pro and getting quick and easy goto's all of which are visible in a 10mm ep with # reticule (although often not centred). I've not felt the need to go down the GPS route as it remembers the location and entering the time/date takes no more than a few seconds. So far I've only used it at the mount rather than from laptop/phone/tablet ect. One question I do have is about controlling the scope from my laptop. On the SW hand controller I could set it to 'PC Direct' bypassing the HC for remote control. ?? How do I connect up when using the Celestron Starsense HC ? Do I connect my laptop to the Starsense HC (via the usb on the bottom) or do I plug direct into the Interface Box, bypassing the controller ? I did have a quick try after updating the Starsense HC firmware. The firmware update went OK so I know the laptop could see the HC/Interface box/SS Camera and know it was using COM 3, but couldn't get any software (stellarium/CdC/Astroplanner) to see or move the mount. Any info greatly appreciated! Thanks
  10. StarSense for Skywatcher mounts

    Hi Jamie, I'm using my Starsense on an HEQ5 Pro with a Vixen VC200L. So far I've done everything at the mount via the hand controller, no wifi, gps etc involved. I will send Celestron support an email, but will wait until after I do another run. Even if I don't see the issue again I'll report it. I have moved the location of the Starsense on my scope to allow for better positioning of my guide scope and also to allow me to keep my Telrad, which I'll be keeping on the scope (really useful during Manual Align). As I have moved the Starsense I want to do a Calibrate Centre again. I have also changed the way I have the Starsense attached to the small camera bracket. Initially I followed the instructions in the manual (page 9), but for some reason it always looked wrong to me and so I reversed it in the bracket. It sits perfectly and as the new position in the bracket moves the Starsense forwards it's out of the way when I'm looking through an EP or adjusting the camera etc. Al
  11. I've had a Starsense for Skywatcher for a few days now and only really had 2 quick goes with it. Worked both times straight out of the box, which I'm happy with as I've seen others having issues. When I say 'worked', there were a couple of times it locked up during an auto align and the HC was totally unresponsive. On both occasions it was looking almost straight up towards the zenith. Power on/off & start again! I did a Manual Align, followed by a User Auto Align and it's not happened since , I did try a number of other auto aligns to check and all now seems OK, but time will tell on that one! It now auto aligns using only N, E & S .... my W horizon is mostly blocked by our house. I know that in theory the SS means you don't need an RDF, but with my admittedly limited time using it, I did find my Telrad was a great help during the manual align. As for goto accuracy, well my set up was very quick (pushed for time on both occasions). A very rough PA by pointing the scope N, a quick look through my Telrad ..... "Yeah that's about North!" was about as much as it took. Then an Auto Align and first time Calibrate Centre were giving me goto's where the object was within view in a 9mm EP, not centred but visible each time and each time was less than 5 mins from switching on the power. I imagine with a better PA and a few calibration stars things should improve. I'll be running through the Calibrate Centre routine again next time as I've swapped the position of the SSA on the scope to give my guide scope a better position. For visual observing it does seem to make things much quicker and easier ...... not tried any (guided or unguided) imaging yet, but if it gets me on a target quickly so I can switch over to the guide cam then I'll be happy. Early days (or nights) but looking good so far! Al
  12. StarSense for Skywatcher mounts

    Interested in any updates on the SSA from Skywatcher mount users. Earlier this week I got a Celestron Starsense for Skywatcher and have managed 2 quick sessions with it on my HEQ5 with Vixen VC200L. I did see a couple of lock up's very similar to those reported earlier in this thread by Jam1e1 here: It only seemed to happen during the auto align when looking up at the zenith. I then performed a Manual Align followed by a User Auto Align and not seen the lock up since. Still have a few things I want to have a go at that should improve the goto accuracy. Currently with just a rough northern alignment and a 'Calibrate Centre' I'm getting goto's that are a little off centre in a 9mm eyepiece - that's without the Polar align or additional calibration stars, so I'm fairly happy with that (for visual) One thing I'd really like to know is if anybody has managed to use the Starsense for the initial goto and then switch over to PC control? I have a few software packages (astroplanner, PHD2 & CDC in particular) that use ASCOM for telescope control and interested in knowing if/how I go about running this when using the Celestron Starsense HC What I'm hoping to be able to do is get things running under the SSA and then swap over for some imaging, using PHD2 for guiding. Not had a chance to even start looking at this yet but not clear if it can be done or how I go about it ....... so any input greatly appreciated! Thanks Al
  13. My webpage 'waterfall' now has 2 waterfall images, I've added a 10 min trace alongside the 60 sec one. http://ukstargazer.net/radio-meteor-detector/meteor-waterfall/ Outside expected meteor showers I'll probably just show the 10 min one as it cuts down on the amount of images that need uploading (every 10 mins rather than every min). As for interpreting what we see, I'm not sure but yesterday I got an email from Zooniverse on a new project on the BRAMS tranmitter https://www.zooniverse.org/projects/zooniverse/radio-meteor-zoo These is some info on their website that may help https://www.zooniverse.org/projects/zooniverse/radio-meteor-zoo/about/research But it's more directed towards identifying what is or is not a meteor rather than info on the meteor itself.
  14. My detector has been back up and running for a few weeks now and seems to have settled down. My webpage now has a 60sec and 10min detection trace running and auto updating. The 10 min trace has only been up for about an hour or so, but seems to be working. It means I need 2 copies of SpecLab running, but the laptop seems to be coping OK. http://ukstargazer.net/radio-meteor-detector/meteor-waterfall/ (The 'waterfall' pages should auto update.) Good job my detector is working as we had 100% cloud cover last night so couldn't see a thing.
  15. Hi, I used http://www.innovantennas.com/ for my 3 element OWL Yagi, if I remember correctly the price was about £40 2 years ago They no longer seem to do the one I got - but very similar to this 4 element version http://www.innovantennas.com/our-antennas/view/productdetails/virtuemart_product_id/331/virtuemart_category_id/35.html It needed assembling when it arrived, but comes with clear instructions and was very straightforward (a few small nuts & bolts) and has worked without any issue for the last 2 years. For cable and connectors I went to our local Maplin. I was also getting confused over what to get so to get things working I simply bought one of these 10m cable kits http://www.maplin.co.uk/p/10m-cable-kit-a98jh it terminates in a BNC connector but comes with a BNC to SMA adapter which plugs straight on to my FUNcube Pro+ dongle. I had to the BNC off one end to connect to the Yagi It was always my intention to change the cable and connectors eventually to try reduce any noise etc .... but it all works so I've never felt the need and again everything is working just fine. Can't help with the telescopic mast, Maplins do one but don't know if it's any good or not. Al http://ukstargazer.net/radio-meteor-detector/
