  1. Hi, I tried a composite image of first quarter moon together with a full moon, the bright part was taken in RGB with SX694 mono camera and it was 6 pan mosaic with a C8 with FR while the full moon (darker part here), was taken with a WOGT81. David

    2sd pier

    Now in action. Seems to work very well. Only a few shots before clouds came in tonight, added to some previous andromeda picture
  3. hi i just posted a description (quick) of my 2sd pier (’light one’ noheavy duty gear), see my post david
  4. Hi just wanted to share building a quick and cheap pier for my avx - 2 brake plate - 20 kg concrete - 4 M8 bolts - a premade concrete block for patio, deck , with 1 central top bolt about 50 kg, 70 cm height) - a square block for the base i used some few blocks of pavements, digged about 30 cm deep, pour concrete and add on then square block and pier, to cover about almost allup concrete. so we will see if it is robust enough and handles vibration. In any case - really quickly done, cheap (about 70 euros, brake plates being the expensive part
  5. Both: nebulosity to capture and pixinsight for processing. Nebulosity is really simple to use, to set up and easily integrated with other (it works fine with plate solving astrotortilla, as well as for dithering etc). Sequences can be built easily (not that user friendly but once you have save few sets scripts then you are ready to go! And I remember to have seen a script generator for it somewhere). Its focusing function is wonderful, after a while, it will just take a minute and less. I did try some other capture program, but always came back to Nebulosity. I never had a bug with it (I
  6. Hi, Long time I did not post. Here is the Soul Nebula from last week Taken with my WOGT81 on avalon M-uno. 17*10 min each S, Ha and OIII Enjoy
  7. interesting. the sun was orange like on the picture this morning up here in south sweden too (abnormal temperature for the season.. 16-17C). Never seen like this before.
  8. Hi, I had proper conditions tonight and happy to report the issue is definitively much better. Below are luminance at bin 1 (right) and bin 2 (left) for resp. 5 and 10 min after adjustment. Clearly no problem for bin 1 while for bin 2 I would say there is still a slight higher intensity on the right, but surely no more bleeding out of the star of 1-2 pixels as I have had so far I have then taken shots of a previous targets and by analysis from pixinsight, I got lower FHMW, lower excentricity, to levels I have never reached so far . So to my satisfaction So thanks St
  9. Hi again I did adjustment according to instruction, and i had a little window to test yesterday evening (unfortunately high clouds and humidity). i tested on vega with my C8 and focal reducer, at different binning an short time. it looked all perfect, i then run on smaller stars and longer time to saturation and it also looked perfect (and no black bite). I did not use my dew heater to avoid any heat current defects, and the corrector plate quickly turn totally wet and more clouds came. So it looks the issue is adressed but i will need more good nights to confirm. I am only co
  10. Steven, what do you mean as "a black bite will be taken out of the stars" if djusted too far the other way?
  11. Hi, I did contacted Terry from SX and based on the input given, indeed he strongly suspect the antiblooming filter and a voltage issue leading to overflow to adjacent cells typical to the Sony sensor used (sounds then also confirming what I see: effect is strongest when I do not have any filter, a bit less with RGB and basically almost none in narrow band as saturated pixel are much less in NB). I am not an electronic and sensor expert (but engineer physics background), it all make sense to me. He gave instructions how to fix it which seems simple to adjust and I will give i
  12. thanks Steve, it sounds like you know the issue, I will then check with Terry at SX, always great support (I love my SX, great camera no doubt!)
  13. and checking another set of data with the WO and an even clearer case this time (here again imaged in RGB -while I typically image in NB with my WO and hardly see such effect in NR, I guess the NR take away so much on the soft side, giving non noticeable defects (does that make sense??) . As always, once I processed my images, it is hardly shown on final processed image (apart of course if you go down to look at the pixel size as I show here). So I can live with it (but in any case it could still be good I am sure it comes from the camera or it comes from scope or something else)
