  1. Thanks Peter. I agree. I've seen many variations on the color of this target, most being bluish around the core. But then I've seen several of the brown/red/purple variety more akin to what I got here. The channels seemed to be reasonably well balanced. I often struglle in processing between pulling out what I expect to see based on other images vs what I actually get. I wish there were a simple way to determine "true" colors. Derek
  2. The color on this one is a bit unconventional based on other images that I've seen but is consistent with what I got years ago when I shot it for the first time. So I stuck with it. Thanks for looking http://www.pbase.com/dsantiago/image/159830637 Derek
  3. Wonderful image! The contrast between the ethereal nebula and the Bok globules is striking. Derek
  4. I use StarGo with my M Uno. It works well and simultaneously with Starry Nights pro plus 7, Maxim LE, PhD2, Alignmaster, Sequence Generator Pro. I have no experience with EQMod. With regard to support, Avalon provides superb and prompt support for this software. Derek
  5. I agree. If these were available in the states I might have gone for it. So many good things about it. Derek
  6. I tried for some time to do guided imaging with an LX90 years ago, and could never get more than two or three minute long exposures. I think I had a lot of flexure due to inability to lock down the primary mirror. After moving to an LX200 I had no problems. AB, I'd love to see some of your some images. Fifteen minute subs would be remarkable with that set up. Derek
  7. Thanks Gina! Looking at your signature, you seem to be very well geared up already. And what I wouldn't give for a roll off roof observatory. Derek
  8. Thanks Olly! I have got to say, I am very impressed with the new Edge thus far. Not only is truly sharp from edge to edge, but but it holds collimation remarkably well. I had an unfortunate incident where my mount got tipped over with the Edge on it, slamming to the concrete. I was certain it would be out of collimation if nothing else, but no it remained perfectly collimated. Also the temperature change coefficient is remarkably small for an SCT. Minimimal refocus is needed with my Optec TCF even over a drop of 8C overnight. Regarding processing, I did use a touch of HLVG. I still use Photosh
  9. Thanks Martin and Paul! This one gets a bit neglected with all the other great galaxies in that region of the sky. But it's got a lot to offer in terms of color and detail. Derek
  10. This is a small active galaxy in Canes Venaticci. There are numerous star forming HII knots that would probably pop with some Ha added. This is my first completed long focal length image on the Avalon M Uno. Image scale is 0.65 arc-sec/pixel with a C9.25 Edge and QSI 540. Thanks for looking. http://www.pbase.com/dsantiago/image/159545730 Derek
  11. Thanks. Yes, I think I'll try PhD drift align. I've always done manual drift align but was looking for something a bit less time consuming. Derek
  12. Hi. I've been trying to use alignmaster which seems like it should be a great program. However, One of the two stars in any pair is ALWAYS too low on my horizon, ie: lower than 25 degrees altitude. I've tried to edit the Sterne.txt file by adding stars and removing stars. I've even tried to eliminate all stars except for two that were well placed, forcing the program to use the stars that I wanted, but this was not allowed (no pair showed up as an option). Has anyone been able to work around this problem with the star pair choosing algorhythm? Thanks. Derek
  13. Hi all. I have a new Celestron Edge 9.25 for imaging, with a QSI 540 wsg, SX Lodestar on OAG and avalon M Uno mount. I am looking for an opinion on automatic focuser solutions for the Edge and wonder what the rest of you do. I would like to continue imaging unattended. Presently I have perfect spacing / backfocus and balance with a standard Celestron T adaptor and small spacer. While I have considered a motorized Crayford type focuser, I would rather not mess with the backfocus and weight, and would like to have flexibility with backfocus in case I decide to add a FR (I have the AP CCDT67) o
  14. Harel Boren described these Bok globules in the Rosette as "Leaping Puma" which fits quite well. But last night at least they looked a bit different. This a combination of Ha data taken with QSI 540 wsg on Edge 9.25 and older color data through the SVR90T. Have a joyous Holiday! Derek
  15. Thanks. The extra exposure time allowed me to capture a bit of that OIII "stalk" that I hadn't seen on many images of M1. I recall I had to "experiment" quite a bit with the palettes to get that color result. Derek
  16. As Olly mentioned, and he and Sara demonstrate, the final image is what determines whether or not our mounts are performing up to our expectations. If I don't have tight, round stars after long exposures, then it doesn't matter how much sleep I got. I imaged for years with a fork mounted LX200R and got satisfactory results, but lost many subs due to poor guiding, and spent hours in processing trying to get misshapen stars to look better. So when I decided to upgrade to the M UNo, the primary factor was expected superior tracking, with no meridian flip requirement being secondary. I chose the
  17. It just seems to me that simpler is better. I understand that many do fully automate their flips and some do it unattended. But I wonder what percenage of GEM users actually do sleep through the night, getting 6-8 hours of uninterrupted, unattended imaging? Plate solving, image rotation, finding a new guidestar, or more flats if rotating the CCD. Yikes! Doable yes, and I have great respect for those that do it well. But for me, without a permanent setup, it would be a headache that I would rather not deal with. And honestly, why would anyone? So if a fork variant mount could be developed tha
  18. Hi Callum. As was mentioned, DEC extenders are available in multiple lengths which have columns that don't impede the polar scope line of site. However, if you are mounting a heavier SCT like a C11, you need to position the OTA closer to the polar axis in order to achieve proper RA balance. In this instance you can't use a long columned extender. But the mount also has an optional off axis bracket which can mount the polar scope on the side of the fork arm and allow you to use the polar scope even in this instance. Derek
  19. http://www.pbase.com/dsantiago/image/142979701 This was my attempt from a few years ago. 12 hours total exposure, 10 minute Ha, OIII and SII subs with 90 minutes each RGB. all subs were binned x2 except Ha. Taken with QSI 540 wsg on 10"LX200R at f/10. I can't to try this one again with my new mount. Derek
  20. Until recently, I imaged for years with a fork on a wedge (LX200R) and was able to get decent shots (even an APOD) with FL as long as 2500 and subs as long as twenty minutes. Granted, it took a lot of effort to get to that point and required a quality wedge (Milburn) and accurate guiding. The wedge and fork in the OPs picture seem pretty flimsy though, and without guiding, subexposures beyond a couple of minutes would not likely be possible. The simplicity of a well performing fork/wedge system, however, is a beautiful thing. Derek
  21. Hi Pete. The fork arm actually has six adjustable positions, A1-3 and B1-3 with B1 moving the fork futhest from the polar axis, and appropriate for the heavier scopes with the greatest diameter. There are several available saddle plate extenders, including columned extenders that allow you to use the polar scope with OTA attached. So long as you use the proper extender to raise the rear of the imaging train above the fork arm base, there is no risk of it hitting the base. It just means that you have to adjust the fork arm and use a small counterweight or two. Derek
  22. Hi Barry. I've nothing but good comments from Avalon users thus far. I'm surprised that they aren't more popular. Derek
  23. Yes, Pete, it seems that the Linear is the better selling of the Avalon Mounts. For me, no Meridian Flip was the selling point for me, alas the M Uno. The no maintenance, no tinkering belt drives and no backlash common to all Avalons is also a great feature though. FYI there is an Avalon Yahoo Users group started by Ed Thomas of Deep Space Products (US distributer) but with very few members thus far. It would be nice to have a rel support forum for our mounts. Sign up if you're interested and share your experiences. Derek
