  1. I spent a long time waiting for a suitable adapter from QHY for a PoleMaster CCD for my AP Mach1 mount. There were postings from the company that one was on its way, but it never materialised. So, in the end, I came up with my own solution, which others might want to take advantage of. Essentially, I designed an adapter in Onshape and then sent it away to be 3D printed (I don't have a printer). The design works really well and sits over the polar scope exit port, and while it has three holes to accept the thumbscrews of the sliding door, it sits so snuggly it doesn't really need them. https://cad.onshape.com/documents/6399e6c65d7ca220918c69e8/w/d68b250f8767100c43389209/e/91882ebb44b3b26c6c192228 If you open the design in Onshape (using the link above) simply right mouse button click on the tab at the bottom of the screen to export the design in a format suitable for your 3D printer. Here are some picture of my adapter fitted to my Mach1 mount. As you can see I did fit a QHY PoleMaster adapter for AVX mounts in addition to my adapter. I admit this is a bit over-the-top, but it is convenient for installing and uninstalling the Polemaster camera. If you wanted to save money you could screw the camera directly to my adapter. You could then just push fit the camera and adapter into the polar scope exit port every time you wanted to use it. Like I said it is very snug when I had it printed. Sorry about the bad quality of the pictures - let's hope my astrophotography is a bit better ?? Hope some Mach1 owners find my design useful - I'd be interested to know if anyone actually prints my design....
  2. I thought this camera had a lot of amp glow that needed processing out. Your images are fantastic and don't seem to show any glow. May be I am missing something..
  3. Hi John78, Yep the down sampling and the modified custom line has done the trick! Thanks very much for taking your time to help. As I'm new to this, it seems that I have to get the parameters just right. How much would the settings you have given me apply universally? Or will I need to teak them from photograph to photograph. One reason I ask is the picture you solved for me was a unguided 9 minute exposure, which is quite a longtime (). Admittedly this was at ISO 800. So for instance if I took a 60 second exposure at 800 ISO, there would be a lot less stars, so would it be more likely to solve? Would I need to tweak the parameters for this new less sensitive image? Again thanks for your help
  4. Hi John78, I should have said that I reinstalled AT exactly as you did..
  5. Hi John78, Many thanks for trying this out for me an giving me detailed steps. Unfortunately despite using your settings it still doesn't solve. Strange how it works for you but not for me.

  6. I just getting my hand back in for the winter season, and I thought I should give AstroTortilla (AT) a go. So I downloaded and installed the software (making sure I followed the tutorial advice on the Lightvortex web site). However no matter what I try I cannot get it to solve using any pictures I have taken. So I am looking for advice. This is one of the files I have tried to solve with https://www.dropbox.com/s/gnvailjzhmrfjhy/LIGHT_540s_800iso_%2B18c_20171012-21h09m43s857ms.jpg?dl=0 I comes from my Canon 7D Aperture Focal Length Focal Ratio Pixel Size Image Size Sensor Size FOV Resolution 106mm 530mm f/5.0 4.31um 5184x3456 22.3x14.9 2.42^1.61^ 1.68"/pixel These are my AT settings: Here is my AT cfg file: https://www.dropbox.com/s/3jznojup2gisgri/AstroTortilla Defaults.cfg?dl=0 I've even tried downloading different FIT libraries including this option Did I miss something? ..get something wrong? Any help and advice is much appreciated
  7. Hi Paul 25 MINUTES is where you messed up. Next time try 25 SECONDS. Take 60 exposures, stack them in a suitable application and then you will have a beautiful equivalent 25 minute exposure - that isn't over exposed. Good luck
  8. What a beauty! You should veryproud! Hey Olly go eat Stub Mandrel's dust. Oh it looks like you already have.
  9. I use an Apple Cinema screen calibrated with a ColorMunki.
  10. Had my second play with PHD2 a couple of nights ago. The results were much more predictable with a 1-2 second exposure, so thanks to everyone for your advice. Below is the graph I achieved. The bit at the end where it goes a bit crazy is me messing with the main camera. Unfortunately I only got to adjust azimuth adjustment before the clouds rolled in. One question I have is; if the clouds hadn't have rolled in, is this curve saying I can get guide and would get good results for say a 500 mm FL scope, or do I need still need altitude adjustment, and possibly one more iteration of both az/alt?
  11. Thanks everyone for your advice. I naively took the defaults and did not consider exposure as the Lodestar X2 seemed to lock onto a star without issue. I will try with a 2 or three second exposure when the skies clear again. silos, my guide scope is a Borg Mini which has a focal length of 250 mm libraryman, yes the scope was on the west of the mount. Is that a bad thing when using drift aligning?
  12. Last Friday was my first time out with a guide camera (Lodestar) and the first time with PHD2. My aim was to use the drift alignment wizard in PHD2 to align my mount and of course to find out a few things along the way. I read up a bit on how to use the drift alignment wizard, but things are a bit abstract until you have a go. I started by levelling the mount and casually aligning the mount using the mounts polar scope. I then slewed (by hand) the scope to point toward the intersection of the meridian and celestial equator. Then I started PHD2. I focused and then calibrated the Lodestar. I did not change any other settings. So everything was set to PHD2 defaults. Then I kicked off the Drift alignment wizard and thats where the fun and games began. Despite 2.5 hours of attempts I could not get the graph for Dec or Ra to run level. I could get it to start pretty good but after 15-30 seconds the curve would drift off into the wild blue (should that be black) yonder. Below is my best curve. Not good I think you will agree. The magenta circle was leaping all over the place, so my attempts to shift the star to it using the azimuth screws seemed pointless. In the end I tried to various iterations until the graph transitioned from pointing up or down. I never managed to converge on a solution. Can anyone give me the benefit of their experience with PHD2 drift align. What am I doing wrong? I guess I have missed something fundamental?
  13. I recently acquired a Lodestar, which I want to use with my Mini Borg as a guide scope. However I don't want to put the Lodestar straight into the Mini, because it only has two crappy clamping screws and not a nice compression ring. I don't want to chew up the outside of the Lodestar, with super primitive clamping screws. Can anyone suggest a way to connect these two together? I think the Lodestar has a 1" email thread on it. So is there a 1.25" nose piece/extension tube with a 1" male thread available anywhere? ..or maybe a click stop focus ring, that could do the same? Would this be any good http://www.firstlightoptics.com/adapters/low-profile-125-nosepiece-c-threads.html I'm not sure what a "C" thread is. Is it the same as a 'CS' thread ? I guess this could be good too: http://www.firstlightoptics.com/helical-focusers/borg-helical-focuser-s-7315.html Many thanks
  14. Hi Tim, I use LR for daylight photography and while it is good for cataloging and making simple edits (boosting shadows, adjusting colour balance etc) it is definitely no good for astro work. For instance there's no staking of images function, star alignment and as Francis says it would not understand FIT files.
