  1. Hi - The LDX75 mount is EQ controlled by Autostar ...
  2. I have been at this AP for a few weeks now And wish to PEC train my mount now as the lost subs is starting to annoying me a bit as I lose about half of my 2 minute subs. Before I go to guiding I'll try some PEC to see if I can improve on that. What I have is a Nikon DSLR and I am hoping that I can use that to train the LDX75 mount. Is this possible ? What software do I need ? I tried PHD using but I don't seem to be able to connect to the camera ...
  3. Stars had halos on latter pics but no dew on the lens so I assume high cloud to blame but still, got a few subs in:
  4. Thanks for looking .... The second one has the flattener! It has more ca as well so not impressed - scope is 80mm f6 so I assumed it would be fine but it ain't. Is it faulty or simply not compatible ? Anything else to consider here before I send it back ?
  5. I just put the skywatcher flattener on my Meade 5000 F6 APO 80mm and I took some 10s exp images with/without the flattener - can you tell which one has the flattener on ? Should I even expect it to work on my scope! Flattener: http://www.firstlightoptics.com/reducersflatteners/skywatcher-field-flattener.html First image: Second Image:
  6. I used Lightroom to get the black/colour balance after stacking. No not used gimp yet ... what processing do you mean ?
  7. That's 52 subs across different exposures and iso - seems to work well enough.
  8. Orion's sword this evening .... took a load of subs ranging from from 1s to 120s to get like a HDR effect. Stacked in DSS using the entropy algorithm ...
  9. Thanks. Well, as to targets, I'll point my scope at anything I can get to from 58 degrees north And after reading stuff in that link I am looking at a UHC filter and O3 filter, and possibly a H beta one at some point if I ever get a ccd. I have had my 12" lx90 for 8 years and only used it for visual use so those filters will help out a bit there I think. As to imaging, I'll have a play and see what they do for that ... Another question - how do I attach these filters, assuming 1 filter can be used for both my scopes ? I use 2" eyepieces in the LX90 and a t-ring with nose for attaching the camera to the meade 80mm frac. I really don't want to buy one for each scope!
  10. I have just started out on imaging and fancy trying some filters to see what they can do for my setup. I am using an unmodified Nikon d5300 with an unguided 80mm f6 app (Guiding will be sorted in due course when I find some good used kit). What filters would be useful for me? I am considering UHC, ha 40/12/7 mm (what's the impact of different nm?) And maybe O3, S2 as well ...
  11. Not guiding yet and I can get 90% of subs at 60s, 70% at 120s and about 40% at 180s ... probably losses due to PE so next step is to get guiding sorted. Sp, with that caveat: Had a go at the horsehead this evening - at least its recognisable ISO was too high (half of subs at 6400 to see what it does) so a bit noisy .... And then saw the Rosette nebula on the chart in a decent position so had a go at that too ... not impressed but its sort of there:
  12. Duh! I actually mixed up 2 sets of subs - some for M33 & some for M101 !!! So, here's the M33 image as it stands now after some flats applied - one more decent session and maybe some pruning of imperfect subs and I'll get to where i want on this I think. Then I can fettle the PP
  13. Having difficulty getting M33 clear, comments welome : subs = 120s iso1600 x 20, 60s iso 1600 X 20 + same DARKS Got M51 as well ...
  14. Ha ha ... this processing is getting to be an OCD candidate !!!! Trying different options in DSS ... and PP
  15. I'll be on this for a week I think lol ... many lessons being learned here. Having a play with this a bit more and homing in I think - This one is a bit gimped (will try and get by without photoshop ..).
  16. That's it, thanks Looks much better .... is that in photoshop?
  17. My shot was 3 mins in moonlight so maybe not beneficial to the same degree but at that price it is worth a go I'd say ...
  18. Looking into this, thanks! I have lightroom but not photoshop - is there a decent freebie out there that will get rid of the green stuff ?
  19. I had a go at M81/82 last night, I collected 30 @ 3 mins iso 800 and 22 at 1 min iso1600 (lost about 15 overall to wind/trails). First proper go at anything so playing with the settings to see what effect they have. The moon was bright and washed out most of the sky visually, and a few clouds were whizzing by so wasn't sure what to expect tbh. Battery ran out after taking 5 darks and no flats so processed what I had. Here's a single 3 minute unguided sub straight off the camera @ iso800. Given that I can easily get 3 minute subs unguided will a light pollution filter be of significant benefit (more exposure time but more contrast) ? Secondly, made evident in the second pic with some contrast adjustment, there's something up with the sensor I think (bottom edge on the left) and I have now seen this on daytime shots as well and when using different lenses .... on bright images I don't see it but can make it visible if I try. Any other comments welcome .... Raw Image: Contrast Adjusted: Final stacked image with only 5 darks applied - still working on it as I seem to lose a lot of definition if I make the background consistently black.
  20. I ordered one of these this morning, I am not looking for perfection but from what I've seen it will do nicely
  21. Hopefully it was not a flukey mount alignment. Really looking forward now to a very dark settled night to see how far I can push it and what comes of it Researching likely targets now as the weather is so rubbish ...!
  22. Bought a second hand 80mm apo a while back now and needed a mount so recently found an LDX75 at a good price - tonight was the first chance to actually get out and shoot anything so in spite of the gusting wind and the patchy cloud cover with showers I aligned it as best I could behind a wall offering some wind protection and took a few shots, primarily to see how long I can go unguided for. M45 was in a good spot but the bright moon was fairly close so not expecting any nebula to show. I managed a few before the rain come in, the one attached is a 4 minute exposure @ 100 iso, the last one I did. First time the camera has been over 30s as well Scope is a Meade 5000 APO .... on the look put for an 'inexpensive' flattener now I think.
  23. A bit of gaffa tape saves the day. I ain't complaining though as it works and for what I paid I am happy with it. I even managed to see some stars tonight between the clouds so gave it a go in spite of the F6 gusting wind! Need a new thread as not M42 and not an alt/az lx90
  24. Mount arrived today, seems hardly used. I have played with it and its currently tracking stuff from my lounge and slewing via autostar, lol. I can connect from the PC so can use a software guider when I get to that point ... 2 issues are apparent though - there is what seems like a dodgy connection for the HBX lead (have 2 to test with) into the mount socket - keep weight on one side and its fine. Also,the motor casings will bump into each other if star is low ... still sussing that one out but It kept selecting sirius to align on which was too low .. Oh, had forgotten how to polar align accurately, could not follow the instructions that came with it but eventually remembered how I used to do it years ago .. lol!
