  1. The original image was a bit washed out on my monitor but after a quick levels it´s very nice! I don´t know if this is too dark for everyone else but it looks ok on my monitor. I love the detail in the wispy bits: it needs some flats and more processing.
  2. I´ve not posted for a while but everything appears to be working AND it was clear last week (I must have sold my soul without knowing) So I imaged a few of my favourites: NGC7635, bubble neb, is HA 20x600s NGC6888, crescent, is HA 18x600s Soon be winter and time to batten down the hatches ;-D
  3. What a wonderful thread, a shining example of the good and bad side of forums all in a neat package. Well done Tommy B some nice work there and a nice reply as well. I rather enjoyed reading the start and thinking I wonder if he's on here and then that wonderful moment I got to his reply. Sent from my XT1032 using Tapatalk
  4. I would put more details but I keep getting jumped on by my 3 and 5 year olds if I am trying to do anying thats more than 2 mins! Sent from my GT-N5110 using Tapatalk
  5. You can get a block of 8 relays cheap from china and you can supply a separate voltage to the relay circuit. I found that without external power I could command 6 relays. Theres still a nominal current draw on each output when externally powered but I can't remember what it is. Sent from my GT-N5110 using Tapatalk
  6. I did fourier transforms at uni and had no problems with the theory, I quite liked it. The problem is that this is a VERY comprehensive book that is worth it as a reference book but in general isn't a book most people are going to be able to read cover to cover. MIT have lots of course materials free online so I'm going to go through a few of those and then cover the relevant section in road map. Sent from my XT1032 using Tapatalk
  7. I enjoyed the first couple of chapters and have since looked at relativity and a bit on euclidean geometry. Sent from my XT1032 using Tapatalk
  8. I am continually attempting to read it but lack knowledge of the mathematical notation used in the book. I need to sit down and first learn a couple of the chapters where he goes through that stuff, it's very heavy going. There are sections in the book that are easier to read so I find myself flicking through it and getting what I can out of it. It's very much a long term project for me.

  9. You are a star! I've been thinking of where to get that gear info and you've posted it here. I can go back to daydreaming now. Sent from my XT1032 using Tapatalk
  10. Oh I like the electromagnet idea. How small do they go down to? Sent from my GT-N5110 using Tapatalk
  11. now there was no need for that! [emoji13]I'm having fun waiting for clear skies, Sunday was clear but lots of moisture in the air. Sent from my XT1032 using Tapatalk
  12. I think you need a new scope, mount and fliter there's a load of red mist in front of the beautiful stars....not good! Sent from my GT-N5110 using Tapatalk
  13. I could just copy and paste the same comment again and again onto you image posts. Instead, my new anticomments! Where's the star bloat and halos? Very dissappointed in this image...distinct lack of artifacts and satellite trails as well! ;-D Sent from my GT-N5110 using Tapatalk
  14. Lovely image Earl Sent from my GT-N5110 using Tapatalk
  15. How's the noise on the pictures? I have been reluctant to use my camera as I tried it last year and it was very noisy, qhy5 btw. I may dig it out again but I'm starting to think I may need a second pc in the observatory as the usb ports on the laptop are already overloaded, you have to connect the devices to certain ports of lines start appearing during image downliad and stuff starts glitching! Dome or flat glass/plastic? Sent from my GT-N5110 using Tapatalk
  16. What a great thread, looks good Nick. I'm going to have to re-read from the start to understand it all ;-) Sent from my GT-N5110 using Tapatalk
  17. I've installed it but am waiting for all the initial bugs to be ironed out. It was up to 6.03 the last time I looked. Fortunately you can install version 5 and 6 on the same machine but I won't be changing over yet as 5 works fine with ACP, if it ain't broke and all that. Sent from my GT-N5110 using Tapatalk
  18. Most of my problems come from usb cables and the usb hub. You'll just have to try and see but I have only one 5 m cable and I paid a lot for it, not been a problem. I've had strange things on usb 1. Lines showing up on image due to too many devices on hub. 2. Cheap hub causing intermittant failures. Sent from my GT-N5110 using Tapatalk
  19. On the power side getting a UPS installed will protect you from power spikes and the odd dip. I've got lucky so far but here in spain the supply us very bad some days. With the ground of the power supply and controller it is good if you can make sure that they are connected to the same earth or ground circuit. I've worked on 2 panels where someone had forgotton to connect the ground wire on the second panel to the first. What happens in that case is you get a floating ground basically I got a 180v, but low current, shock off the second panel whilst leaning on the first. Heres a link: http://en.m.wikipedia.org/wiki/Floating_ground So for the ground wire I'm not 100% sure on the 12v side as its through a transformer. Definately get a UPS though that will give you some piece or mind. Sent from my GT-N5110 using Tapatalk
  20. I don't get a chance to read much if the forum these days but your threads are always fantastic. I love your designs and the way you think things through. Keep up the good work gina your an inspiration. How's your roof automated? I've forgotton what you did on that, I'm about to put a gate ooener on mine. Sent from my GT-N5110 using Tapatalk
  21. There's a fuse on the input so if it's done its job you should be ok...unless you wired it backwards at any point. I blew a fuse on another powersupply the other night, just needed a fuse change. Sent from my GT-N5110 using Tapatalk
  22. I know how you feel, my first attempt with my mesu was a disaster due to poor shipping/packaging (the packaging is now better) and a dodgy motor that kept slipping (after a bang from ups). I then sent it back to have it completely checked and the scitech ii fitted, no problems since. I've had a few power cuts but no problems from the scitech afterwards. I power everything from a custom power box that has 220v to 24v transformer and supplies up to 20A. Each 12v supply runs through a relay so on power fail it has to be re-armed, as it were. I'll shortly be adding a 1200va ups to shut everything down on power failure. so no problems with the scitech ii and power for me. isn't there a reset button on there? Sounds more like a fuse blown.

  23. When I did my last polar alignment I didnt use the routine for recentering I instead looked at the RA error and DEC error. These show values in your normal 00:20:30 Format showing how far out it is. I then adjust, clear all the cal points, do another init followed by cal pount, following the polar alignment instructions and then check what it says on the RA error and DEC error again. If you moved it correctly it should be closer. So 2 star cal with the stars 30deg apart at least and slightly above the meridian on a similar dec value. Check error and adjust. Reset cal points. Do another 2 star. Check error. Olly, mechanical engineers can only push buttons anything with more than two colours and they become srartled and unresponsive! The software functionality is fine the problem is too many tabs and buttons. This is a standard software problem too much functionality and clutter. Why so many cal buttons? Simplify the damn thing. Why is polar align in different display to PA error? All those numbers are great but I dont need them, I'm sure they're very usefull for a new build mount setup but of no interest to me. I'd reorganise the display and hide non essential stuff. Sent from my GT-N5110 using Tapatalk
  24. I've heard the Sitech described as having been 'written by engineers for engineers.' What's your take on this? This thread mekes me quite glad, numpty that I am, to have the Argo Navis version. You can polar align a Mesu by the drift method in 20 minutes and take half hour subs at 2.5 metres, so you could take one hour subs. Software gone mad? Olly Was your mouth out Oliver! Software doesn't go mad, it wanders slowly to madness picking up subroutines along the way.I'm an engineer!....er...that's not going to help me win is it?The software's very good but there needs to be quick start guide which says "look at these bits...no not those just these. These bits will get you running all that other stuff can be ignored for now".If you do the 2 star alignment its the same as the Argo and works.The problem with this encoder error sounds more like a cable problem and not software, lose wire somewhere.Sent from my XT1032 using Tapatalk
  25. You also get an "unable to read encoder" error if its a coms failure. May be worth changing the usb cable and having a play with the mount to see how it slews, can you use it with the roof on or is the roof too low? Sent from my XT1032 using Tapatalk
