  1. Congratulations! If you find someone to print and expose it, let use know where, It would delightfull to see the print!
  2. forgot to say, my MAK is the 102, not the 127.
  3. well done. Continue, add more subs and try 15 sec. I manage 15 sec with my sky max 127 Alt/az and simple unmodded 1100d. I need to disregard maybe 20-30% of the subs, but typically due to some vibration, the mount is not stable at all. I managed to push to 25 sec also. http://stargazerslounge.com/gallery/image/17221-orion/ and try also M51, clusters, M45: http://stargazerslounge.com/gallery/album/2295-first-images-skymax-102-dslr/ (processed with Nebulosity) No "wrong equipment", simple more precautions and a bit more of work to process ;-), and you can still enjoy some astrophoto at a (extremely) low budget for some few easy targets.
  4. Dear all, a first trial for a star trail and animation Canon EOS 1100d, 18 mm, f3.5, ISO 100, 60 sec exposure. (full moon). Using starstax and then PIPP
  5. The season is back. M33. 210 subs 60 sec at ISO1600, EOS1100d. C8, at 6.3, unguided
  6. Hi you can use the PEC feature without autoguider, by doing it visually: you simply need a very good night without much turbulences. Get as good polar alignement as you can target a pretty bright star near the meridian and equator use the highest magnification you can [i use f25; simply with a 2.5 barlow use live view on a computer with the canon software and use high digital magnification use Al's reticle on your screen and center the defocused star, make sure the sensor in right on the axis start the procedure for the PEC training and do the PEC training download the data to your computer and do several training. Load the data in PECTOOL from celestron. Normally it shall be pretty much same curves. Average them, 3 to 5 shall be enough [exclude some if they look really out| and reload the data to the mount. it takes a bit of effort but this is Worth it. see below post on my Learnings on using PEC http://stargazerslounge.com/topic/189873-vx-mount-pe
  7. MarkPlym, I have the C8 on the avx for now about 1 year and you will not regret. I also shot unguided with eos1100d. At f10, i do manage 60 sec sub for 90% shots being usable/round stars (with PEC training, only done it 2 times in 12 months -visually/manually at highest mag i can-and i am within 4 arc second peak to peak typically while without pec, about 30 arc seond peak to peak with a quick change, so i end up with 60% usable shots for 60 sc without pec. Besideusing the pec function, I recommand a 6.3 focal reducer which makes both pe and poar alignment less stringent. With it, i can then us 100% of my 60 sec shots without problem (pec enabled of course). I even did try at f25 and managed perfect round star 2 min ! (but 1 out 2 is not perfect) The aspa function is good enough for poar alignment in this 60 secxposure time set up f10 or less (i could even push to 2 to 3 minutes when well aligned, but then i may need to discard 1 shot out 3 or 4 (due to the residual periodic error) so waste of total time (and due to light pollution i use iso 800, so istick to 60 sec (and iso1600) and it gives me full satisfaction. See my gallery for results (typically with60 sec sub, at 6.3, iso 1600 with cls clip filter. It works troube free and like a charm (pay attention to well balance the set up and avoid changing too often the set up, slightly east heavy in order to have reliable pec - at the begining i was not balancing well and trying too many different ways to set up, that my original PEC was not usefull very quickly. Keep it simple and make least changes as soon as it works amd gives satisfaction! and yes dewshield and focus mask recommanded Have fun
  8. Long time I have not posted. Mars yesterday evening. Very good transparency, a bit of jetstream, I am quite happy, C8, Canon EOS1100d, 2,5 barlow. About 2000 frames stack and wavelet Reg 6

  11. Hi all My experience with eos and planets: I do all my planetary with canon eos 1100d with 2,5 gso barlow and baader moon sky glow filter either with my c8 or mak102. Connected to my laptop, and using Eos movrec to capture (a freeware, very simple) with its *5 feature. I reach a steady 25 to 30fps. The canon is set to M and i use typically iso 200 (100 for the moon) and speed of 1/8 to 1/20 depending the conditions (the shift from dark to overexpsed is very quick when changing few steps in shtutter speed, one need to experiment a bit). I never tried higher iso (not sure if this could anything, i don t see iso in such cases having big effect on brightness for some reasons, apart bringing noise, the shutter speed is main effect to play with I like the baader filter, it heps for jupiter details and color contrast. It seems also to have also some influence on turbulences. As claimed ( i did a comparison once with/without on same night -it is not huge difference of course but still a positive effect) I record typically 60 sec on jupiter and longer onsaturn and whatsoever with the moon. The movie is directly recorded in avi recoginzed by registax. In case of saturn, i found usefull to preprocess in pipp (with strecth histogram enabled, it helps tremendosly to rebalance the colors correctly), while no differences in case of jupiter. Check my gallery for results. I have no direct comparison with webcam or panetary cameras, as i never had any.
  12. I found a little avi to gif freeware that works well. So here it is
  13. thanks. Has anyone good tips to make a good quality animated GIF (above was my very 1st attempt to make an animated GIF) I made an AVI with PIPP with the original stacked 22 images ( TIFF original format) I have, the quality is way way better than above. I used an online convertor to make this GIF copied above from the AVI. I use GIMP as photo editor and I tried to make the GIF with GIMP, but too much work/trouble to align each pictures in layers. Any software or tools in GIMP known to help out, what process flow to keep up as good quality as possible? Thanks in advance
  14. Hi For a good weather forecast for imaging planets, I am looking at http://www.skippysky.com.au/ it seems to fit well looking at all the details H/M/L clouds, transparency, seeing, pressure, low wind, jetstream. I have been using it for a few weeks and it looks like it correlates very well for final results I got so far (and the best I got was with combination of all above paramters being best -I did not get all parameters at their"best" but say on a high side and got my best results).
  15. A first attempt at animation 60 sec avi, stacked in registax. every 5 min. C8 with 2,5 barlow with Canon EOS1100d
  16. Hi, A pretty good seeing tonight copernicus, Eratosthenes, http://stargazerslounge.com/gallery/image/22129-copernicus-eratosthenes/ plato, Vallis Alpes http://stargazerslounge.com/gallery/image/22130-plato-vallis-alpes/ taken with canon EOS1100d though C8 at prime focus. Avi processed in Registax 6
  17. thanks for the comments. In fact, tonight was not better, too foggy, so I simply did not try. Then I gave it sometime to reprocess it, better to my taste:
