  1. I tried deconvolution but it is not easy. Perhaps I should tune the color saturation and balance a little.
  2. M8 Lagoon Nebula and GC NGC6544. I don´t know if it was a flexure or a guiding problem but only the stars on the upper rear square show some trails. The picture is a stack of only 15x180subs. The QHY parameters are the same than in the Cocoon.
  3. Dear friends, A Cocoon nebula from yesterday`s evening near Toledo, Spain. 34x180 subs plus darks and flats. QHY168C at Gain 10, Offset 30 Temp= -10ºC, taken with APT. Cheers. Mario.
  4. You won't get problems if you use collimation screws on the secondary (7 pounds 3 of them), and a good laser collimation tool like the hotech sca laser
  5. I go for M8 this night, let's see what I can get
  6. Ladies and Gents, The picture of M7, first shared here, has been chosen by Sky and Telescope as the Editor´s Choice of the Week. I guess Skywatcher should give us a gift or something by this promotion, don´t you think??
  7. Hi Sathya, perhaps it is a combination of factors mainly the camera and the scope. The camera is a QHY168C, contrary to a DLSR it does not have IR filter so you have the whole spectrum available, as filter I use an IDAS LPS D1, so I collect all the needed data discarding the LP. Moreover the SW130PDS is F5, so it is a fast scope, this allows along with a good camera, to reduce the time needed for your exposures, I have got even very good results with 60s exposures. If you dive a little in this thread you can see the differences got for the same objects taken with the same scope and different cameras. The SW130PDS is a bargain imaging scope, so what you save in the scope can be used to couple a good camera, the QHY163M, 168C, 247C or the ASI071, 1600 or 294C are very good candidates, or any good CCD like the Atiks 460X or Horizon CMOS. The difference is huge really huge. Also the postprocessing has something to say, with DBE tool from PixInsight you can extract the best from your pictures. I attach just a frame, with the background removed and with the histogram streched.
  8. Dear 130PDS addicts. A suburban M7 surrounded by dark nebulae B283 and B287, also the tiny globular cluster NGC6453 can be seen. 20x180s subs + darks + bias with the usual equipment. It is not easy to catch even here in spanish latitudes due to the LP mushroom, as the cluster does not climb so much over the horizon.
  9. And a M92 field, taken the same day than NGC6823, some galaxies can be seen on the left. 60x60s subs with 30 darks and 30 bias, taken with the QHY168C at Gain 10, Offset 30, Temp =-10C from Brihuega, Spain at 997m high. Cheers.
  10. A boosted retouch of NGC6823
  11. NGC6823 in Vulpecula, an open cluster with embedded nebulosity quite similar to the M16. 25x180s guided subs+darks+bias+flats. Taken from Brihuega, Spain. QHY168C+AZEQ5+SW130PDS Moonlite+ASI385MC+Baader MPCC+IDAS D1.
  12. Sometimes it is unfortunately true. The Nikon D3400 and D5600 have good sensors as well but their modded equivalents in sold in PrimaLuceLab are even more expensive than an ASI071 Pro
  13. Change the camera Neil, the Canon has its years and currently the sensors installed over the AS294C for instance give us impressive results with very short exposures. This picture of M101 was taken only at 20km from Madrid city center, with the Airport behind us. The sensitivity of these new sensors like in the 163, 182, 294 or APS-C like models (QHY168C or ASI071) allow us to increase the productivity on those scarce available nights.
  14. Now a quick processing of what it was my first objective last Saturday, it is a urban M101 field, 68 x 60sec subs + 30 bias + 15 darks. Cheers. Mario.
  15. Dear friends, Yesterday the weather gave us a breath in Spain. So with 100% humidity we went to the city outskirts to try something. Here the Foxhead Cluster, Mag 7.3 in Cygnus, a beautifull open cluster, I guess Alacant took a picture last year of it. 100x30s subs +30 darks+30bias+30flats. with the QHY168C unguided, SW130PDS Moonlite + IDAS D1+AZEQ5. Cheers. Mario.
  16. You can change the focuser to a Moonlite :-)
  17. No they are not, with the M54 adapter the QHY thickness is 13mm, the problem is that the QHY168C has a bigger backfocus distance than the ASI071, I have done my calculations with the TS OAG9 and it will fit well.
  18. option for a 150F4 discarded thanks.
  19. Mmmm, then I have made up my mind, and I will go for the QHYOAG-M. Thanks gents.
  20. To be honest I am struggling with guiding, I use a 60mm finderscope, but last Friday I suffered issues with PHD2 and my ASI385, phd2 was unable to record a proper calibration it spent a lot of time waiting for responses. All my last pictures have been taken without guiding. I also own a SW200PDS so in order to reduce weight I am seriously considering to replace the 60mm tube with an OAG in order to be used in both reflectors. I would like to ask you how difficult is to focus the guiding camera, have you any picture of your set up?, just to figure out how it looks like. I add a picture of the AZEQ5 with the Geoptik head. Regarding the replacement for the 130PDS you are right, a 150F4 UNC CF is around 750 eur, almost the cost of 3 130PDS, also think that CF degrades with outer exposure and specially with sunglight
  21. You also have 150F4 options, they are 600mm so you will have the FOV of a 130PDS. Unfortunately SW does not sell them, by you can find almost the same (GSO) scope under the brands of GSO, Orion, Omegon and TS optics (PHOTON). If anytime I change my 130PDS it would be with one of those, their weight in steel made tube is around 5.5kg and 3.5 in CF, so both options will fit for DSO on the available range for my AZEQ5. Cheers. PS: A quote for you Moise, last week I replaced the head of the AZEQ5 with one from Geoptik which allows both Vixen and Losmandy dovetails, it provides more sitting surface for the scopes. http://www.geoptik.it/index.php?route=product/product&path=93&product_id=23
  22. This is an interesting question, specially for the big amount of 130PDS owners. My scope is 5 years old and there will be a moment in which due to pollution the coating will be degraded and therefore the mirror will need a replacement. Try to ask FLO as they have a close contact with SW, also ask in Teleskop-Service in this page they have up to 150F4 mirrors but anything about the 130P. Regards.
