  1. You are right Prathab, the problem is getting worse. I recently noticed I am now having to bin about 10% of my frames due to Sat trails. The other night, a single 5 min frame had the most so far, 5 trails crossing at different angles. The situation will only get worse now Canada and several other countries want to put up their own Sat broadband constellations. Using Pixinsight I can still see the trails in my images, I use weighted batch preprocessing and it doesn’t fully eliminate the Sat trail. Does anyone have a specific data process that improves Sat trail removal?
  2. I would definitely consider investing in a raid storage system. I have been running a QHY600 mono with my ROR rig since end Dec and even with the limited UK opportunities and a relatively small selection of target Image sets I found my PC (i7) slowed up last week, reason found - the master drive had accumulated 1 Tb of image data in 3 months. For information: each Fits file is 29.878Kb (2x2) and 119.484Kb (1x1), each Master Pixinsight light frame is 179.234Kb and 716.876Kb respectively. I have now changed what files I keep and installed 8Tb backup drives on each PC. I can only imagine how much
  3. Hi and welcome to SGL, now the AP fun starts and looking forward to seeing some images. Martin
  4. Both Mesu’s did a brace of MFs last night using the same settings, with only one anomaly. One of the Mesu’s initiated the MF before an SGP image had finished, so SGP carried on then attempted shutdown siting the guide star was lost, I may have inadvertently configured a telescope setting wrong in SGP and will compare the 2 PCs.
  5. Hi and welcome Cosmic Monk, I used to visit the bases in San Diego and always tried to get Humphrey’s Half moon inn, the live music was great. Martin
  6. All the flat cables that came with my cameras were binned on opening, didn’t want to risk cross contamination with my collection of healthy pedigree USB stock.
  7. Thanks Dr-ju-ju, I reviewed the data on the link and as you say, was not brave enough. What is interesting is how Win 10 has removed the ability of the PC owner to check the USB bandwidth allocation for their PC. This would be vital information to determine the best port allocation for your given system. USB conflicts/disconnects and communication is the biggest fault generator in my observatories and has cost me so much imaging time. Ho Hum back to system fault finding.
  8. I also have the Asi120 mm (USB 2.0 variant) as guide camera on one of my rigs and it has been working fine for ages using SGP & PHD2 with either Atik383 or Qhy 268c or 1600mm on a dual rig setup. Following a recent camera shuffle I now have the 120 guiding and a QHY268M and 1600mm pro as imaging cameras on the dual rig arrangement. During the 2 nights I have finally managed to get some imaging done I have encountered problems with the PHD guide camera (120) image fluctuating and acting strange., this was while imaging with the QHY as the main imaging camera and while the 1600 was connected
  9. Hi and welcome, your first priority is to get to know your new scope, upgrades can wait until you’ve determined what aspects of this hobby you want to take further. Martin
  10. Hi Dave, welcome to SGL. Astrophotography with the SW150p on the EQ3-2 will be a challenge.
  11. Reference the new cap I’m more interested if it make a good seal for Dark frames, the cheap clip on that came with mine let’s in lots of light so is useless for darks. Can someone advise how the new cap performs for darks.
  12. Hi Mark, welcome back and good that you have rebuilt your setup. Martin
  13. Reading this thread it is evident that stuf1978 has his heart set on the 2600, may I offer a few points for thought. I have owned several OSC cameras SX,Atik and QHY and only the ZWO-071 remains from what I would class as my CCD and 1st gen Cmos OSC cameras. My other OSC is the QHY268C, same sensor as the 2600 in a different package. The QHY doesn’t have the built in USB hub, as already said not a problem for OSC. The QHY does offer different modes for data management and comes with a useful rotator/coupler, this does increase the camera back focus to 23.5mm, again not a problem for OSC. There

    Hi folks

    Hi Jon, welcome to SGL. A great start to a fascinating and addictive hobby.
  15. I would think the X2 in the current equipment setup is a close call even at 55mm BF, I only accounted for 1 mm inward focus to achieve the 54.5mm min BF with 9.5mm of spacers between the FW and the OAGM. Thanks for the heads up ref the ASI174MM, looks to be a possible solution. But at £500 delivered the cheaper option for me is to machine 4mm off the front of my X2, as long as I leave some thread I can use it with my SX setups using a 5mm extension. I have the TS130 photoline F7 and Altair 130EDT also F7. I have 3x 3” Altair 1.0 flatteners (51.5mm BF) and 3x Planostar 0.79 reduc
  16. Nice M45 without halos, is that the Chroma filter?
  17. Great thread thanks Jonk and others for the information, you never stop learning. Being told I have spanner hands, I generally struggle when a sensitive touch is needed so I acquired a cheap spring balance which works great for balancing these mounts. As has already been said, both of mine have differing levels of stiction in different places as you rotate the RA & Dec axis even with the motors disengaged, but as Lucas says this is normal for these drives.
  18. Problem After building my new QHY 268M, CFW3-M and OAGM setup I have been unable to get a guide camera to focus through the OAG. While the camera came with layout cards showing this setup for 55mm, I also hoped this arrangement would let me use my 3” flatteners (BF 52mm) with my TS&AA 130 triplets. Is it possible? Having attempted this setup my conclusions are: The minimum back focus (BF) this equipment arrangement can support is 54.5mm for a guide camera with 12.5mm BF. To achieve this BF the prism will have to be set at the very outer edge of the field of view. Note ev
  19. That is the way I operate my ZWO camera’s. With the QHY you are given more control over how to tailor the cameras sensor data to your chosen target, whether this is a good thing or not, only time will tell. Personalised offset and gain values can be stored with a title within the Driver for later selection. What would be beneficial is clear, unambiguous guidance on what startup settings the uninitiated user should adopt prior to developing their own skills. Have QHY already done this in the settings for DSO/Planetary that appear after initially loading the driver software or were t
  20. Nice frame Spongey, great to see. The camera appears to be performing in line with the IMX455 sensor based units, just in a size better matched to a wider range of scopes.
  21. Nice first light SyedT, typically I have had blanket cloud for the past 2 weeks and it doesn’t look likely to clear for another week. May I enquire what version of SDK you are running with?
  22. The only spacer that is threaded for M54 is this one and I measured ( engineers ruler) it at 4mm which isn’t aligned with the diagrams. You are correct my bad, the filter wheel is the Medium not Large, was getting confused with my Q600 kit. Don’t seem to be able to edit the post at present to correct
  23. It is always difficult to recommend a camera for other people as there are many factors that need to be considered. If you are able to buy new and your preference is for a cmos camera why would you consider a first generation unit with its known limitations when the second generation units are already available. The new 16 bit IMX based cameras are a substantial improvement in noise, QE and don’t suffer microlensing. If you are prepared to consider CCD as well as CMOs and used, there is plenty of choice and the market has been buoyant recently with some cracking cameras to be had.
  24. Hi Steve, I have a mix of Pyxis LE, Night Crawler and am currently fitting Falcon rotators which has been somewhat delayed as I chase short thread adapters. The LE is limited as it can only be fitted to a 2” coupling, not ideal for imagery. The NC is integrated with the focuser as a package so limited to OTA by appropriate adapters. The falcon has M54 threaded input and output which integrates nicely with the emergence of M54 in the latest QHY kit and supports larger frame sensors. Unfortunately the lack of easily available thread adapters to connect the imaging components within short back-f
  25. From my experience the way to determine the different focusers is via the assigned COM port and selecting it within the SGP equipment window, via the focuser mechanic button prior to connecting. I keep a note of the different settings for each imaging system, especially important when running 2 instances of SGP within the same PC. The SGP manual is excellent and should help.
