  1. the reason to use PHD is because My image capture workflow is using SEquence Generator Pro which handles the camera, filters and focusing in a seamless integrated way. SGP interfaces with PHD to allow dithering and guiding. SGP will not dither with The Sky as the guiding system to my knowledge.
  2. Hello, Is anyone using PHD2 with a Paramount mount? I have a MYT mount and are trying to get PHD2 to work using Directguide. Everything works fine if I use the relays on my guide camera to guide the mount, however when I try to guide using the USB interface, I get messages saying the ASCOM equipment does not support pulse guide.
  3. Thanks for the comments. It's nice to hear you have had no problems with your mx in 4 years. do you have to perform any maintenance on the mx periodically? i have read different things about maintenance so just trying to clarify the reality.
  4. Hello, I am in the market for a better mount and having done the usual research, I have shortlisted the Paramount MX+ as a potential candidate. I currently have a CGEM so this would be a significant upgrade. My CGEM has ben very reliable over the 5 or so years that I have had this but I have now upgraded my optics and now use a QSI camera which have all added weight. The CGEM is rated at around 19Kg and I estimate that I am currently running at 22Kg give or take a couple. As expected, the mount is struggling to guide for much more than 3-5 minutes before star trailing and I would really like to push this further to 20mins or so. I considered the paramount MYT but I would already be at the limit of this mount hence the MX+ many posts on the forums relate to problems being encountered and assistance in resolving these. Likewise, the Software Bisque forum also appears to follow this same approach, which is totally understandable. What I was wondering is what users of these mounts think about their equipment. Are they reliable? Do they need to be serviced regularly - if so how often and how difficult is it?
  5. It's definitley worth a try. I have the 180 and also the ed80. For small objects, the long focal length of the mak makes the images a better size on my canon. If you are interested, take a look at my website www.imagingexplained.co.uk, there are number of images in the gallery section showing what I can achieve with this scope. Note however that I am a relative beginner so I have a long way to go still.
  6. I use a skymax 180, guided with an ed80. I have imaged m57 with this setup using a eos450. Whilst it's not the ideal imaging setup, I have been able to get a fairly good image, at least for me anyway. I tend to use upto 3min exposures and plenty of them. I would suggest trying it and see how you get on.
  7. There should be a small rubbers flap on the side of the 450. The USB lead connects here. Then use the EOS utility software on the PC to control the camera.
  8. A Canon EOS 450 is fine for astrophotography. It is best used for DSO's. You will need a EOS T mount and also an adaptor to connect it to your telescope. I have a skymax 180 telescope and use a t mount to 2" eyepiece adaptor. Depending on the telescope interface you may need to use a T mount to 1.25" eyepiece adaptor. Discuss your requirement with your local astronomy shop and they will ensure you get the correct connections. To start with, you really do not need much else. Control the EOS from a PC via the USB lead to avoid camera shake when pressing the shutter button.
  9. Many thanks, That saves me a lot of effort. If only thar stars would come out now for a little longer than a couple of hours at a time. Keith
  10. Hello, After quite some time trying various ways to focus my telescope with a DSLR and / or webcam, I finially took the plunge and built a Bahtinov mask. Being the sceptic that I am, last night I tried it for the first time, and was totally surprised how easy it was to focus using this simply device. It also worked visually as well as through the netbook with CCD. I would recommend this to anyone struggling to focus on CCD's. I have a Skywatcher ED80 telescope and I cut out a mask to match this telescope. However, one question that I have is as follows... The Bahtinov mask is cut to match the apperture and focal length of a specific telescope. My ED80 is 600mm focal length and 80mm apperture. If I add a 2x barlow lens into the optical chain, then am I correct thinking that I would need another mask for 80mm apperture and 1200mm focal length? many thanks in advance for your assistance with this question. Keith
  11. Many thanks, This could explain a lot. Next time the clouds clear I'll align on Polaris and try again. If only the skies would clear for longer than a couple of hours!
  12. many thanks, That is what I suspected. I had the alignment with my Meade ETX sorted, it was nice any easy. (But this did take me quite some time to get slick and quick at it) The CGEM is a whole new learnig experience. I must have my initial polar alignment off by quite a bit. Guess I have some more playing to do here. My latitude is 52 according to Multimap. Is the pointer on the CGEM reasonably accurate? I.e. if I set this to 52 degrees is it reasonably accurate? or can the vary by several degrees?
  13. Many thanks for your comments. I have entered my Lat and Long. Date and Time are correct. Is it normal for the alignment stars to be out of the finderscope when performing a 2 star align? The scope is pointing roughly in the right direction towards Deneb, it's just not showing up in the finderscope, I have to slew a considerable distance to get it.
  14. Does the CGEM assume you have a reasonable polar alignment when you start the 2 star alignment process? Am I correct that if you have the mount polar aligned correctly to begin with, then the 2 star alignment should place the alignment star in the eyepiece without any adjustments being required (theoretically that is)?
  15. Thanks, I noticed the date is entered in the odd format. I have this correctly set. I also set the Time to Standard Time, hence daylight saving is off. I next select Universal Time which is the timezone I believe.
