  1. Haha. I have ankle weights on the left arm of my LX90 as well. Balancing takes some time during daylight, with some tape placed at appropriate points on the mounting rail for the weights and the placement of the guidescope. Loosen each axis, one at a time, until the scope does not "flop" to the heavy side. When you're done, you can typically loosen both axis locking screws, point the scope in any direction, and it will stay there. There are a few directions I can't quite get balance, but I can get very close. First time took me about 15 minutes of experimenting on the back porch.
  2. Polar alignment: On my LX90, it typically takes me only a few extra minutes to get excellent polar alignment. Pointing as close to true north with a level tripod (and properly adjusted wedge), I make my first polar alignment. I do the alignment as accurately as possible using an illuminated reticle eyepiece. Right at the end of the alignment, the Meade Autostar tells me where true polar north is with respect to my current setup. I've calculated that my wedge requires about 1 screw turn rotation to move about 33 arcminutes left or right, and 1 screw turn in altitude to move about 55 arcminutes up or down. My second polar alignment typically shows the message indicating less than 5 arcminutes error, as long I was pretty close on the initial polar north.
  3. I am using the Meade Classic and Autostar I ASCOM driver (v5.0.2) with pulse guiding enabled.
  4. I use the ADM 125mm rings as well for my ST80 guidescope. Good luck!
  5. My son and I have the setup for imaging down to less than 10 minutes setup, after getting the scope mounted on the tripod and power connected. It took us a while figure out how to get good polar alignment with our scope, but it's now no longer than it took to polar align for observing. So the extra setup just includes bolting on the guidescope and counterweight, mounting the guide camera, routing all the cables to our netbook (for autoguiding), and mounting the Canon camera. With the camera, we've been able to "see" (in images) much fainter and prettier objects than we ever could have seen visually. Plus, we get to share these with our family and friends. Yes, it took some time and practice and research and a little money to make imaging successful, but it's been well worth the effort so far.
  6. I use a Meade LX90 8" with Orion ST80 guidescope and Phillips SPC900 webcam, guided using PHD software. Fairly simple and cheap for me, considering I already had the small netbook available.
  7. Here is an image of the Lagoon Nebula I shot on 6/30. This was my first real attempt with my new autoguiding setup, so I was pretty pleased.
  8. It depends somewhat on what part of the sky you're shooting. I see less field rotation along the ecliptic, and more near the polar regions. I still do my best alignment, but I don't do any drift alignments.
  9. I had good results from Lagoon Nebula last week in my southern light polluted skies. But I was using a Hutech light pollution filter while imaging.
  10. Yes, the spikes were introduced in Photoshop using the Astronomy Tools 1.6 actions. I'm ready to get out again the LX90.
  11. Second time out with the guidescope this past week. Shot a few pics of Lagoon Nebula. 4 exposures at 6 min each, Canon 500D mod with Hutech LPS-V4 nebula filter, stacked in DSS and enhanced in PS CS5, Meade LX90 polar-aligned with Orion ST80 guidescope, Phillips SPC900 webcam guiding with PHD software, updated firmware in LX90 for autoguiding. This was my first successful attempt with autoguiding. I'm looking forward to much more, once the weather cools off.
  12. I purchased a Canon 500D that I had modified before I received it. Very pleased. Sent from my DROIDX using Tapatalk
  13. I don't have any pictures yet, but will try to get some over the next week or so. I've yet to resolve all the cable and balance issues. I have a Losmandy weight on the bottom rail to help offset the guidescope on the top rail, but will likely have to add more weight on the bottom. I use velcro straps for helping to secure the cables once I get everything connected.
  14. Yes, this works. Camera into laptop running PHD. Ascom 5.5 driver for Meade classic scope, usb/serial adapter with Meade 505 serial cable to Autostar. Autostar has to be patched to work properly to guide the LX90. I just got this working on mine a few weeks ago. Sent from my DROIDX using Tapatalk
  15. I chose to go with the Orion ST80 guidescope mounted with ADM 125mm rings to a Vixen style dovetail. For guide camera, I'm using a SPC900 webcam. Using PHD software and a netbook connected via Meade 505 cable and USB-serial adapter. You could use similar, but get a guide camera with ST4 output along with the 909 clone adapter, instead of the webcam and the netbook. BTW, the Orion package you mentioned does not attach to the LX90 directly. BTW, most LX90s will need their Autostar patched to work properly when being guided. Sent from my DROIDX using Tapatalk
