  1. Thank you for the lovely comments. Every time I was going for M42 I wasn't taking any shors exposures and the core was completely blown out but after reading how other people managed to expose the trapezium I thought I would give it a try and see what comes out of it. I'm pretty pleased with the result. Too bad the "cloud nebula" is in the way of the stars and preventing me to capture more data.
  2. As Orion is not that high in the sky anymore and it goes quickly behind the trees that block my sw view I only managed to do 23 min stacked exposure made out of 2 sec, 30 sec, 1 min, 2 min and 5 min frames at 400 ISO. I did this to try and get the trapezium in the photo. It works but I will definitely need more data and a lot more processing experience. I used dss for stacking and PS and Lightroom for processing.

  3. Hello guys and girls, Looking at the weather forecast for tomorrow it seems that I can finally go out and try to control my imaging session from the laptop. I ran the simulations as many times as I could to understand how it all works. All the drivers and connections are checked so I know they are working. I came up with some steps that I would like to follow and it would be really helpful if somebody more experienced could tell me if what I'm trying to do is the way to do it . Some of the steps will not be used in the future as my Setup will stay outside. If you think that I would have to add, remove or switch some steps to improve my sessions please let me know. All the comments and suggestions are highly appreciated. So here it goes: 0 - Choose the target to image and make a Lights plan in APT 1 - Level tripod 2 - Set home position, 3 - Connect everything to the Scope, mount and laptop 4 - Check the collimation 5 - Balance (unballance a little for imaging) - in RA - a little heavy on the rising side and in DEC - a little heavy on the camera side 6 - Start Eqmod, APT, Alignmaster and Stellarium (EQmod) 7 - Unpark 8 - Disable limits 9 - Quick polar alignment with EQmod polarscope 10 - Enable limits 11 - Set Alignment/Sync to "Dialog based" (APT) 12 - GoTo a bright star and focus with the Bahtinov Aid tool (Stellarium) 13 - Do a Sync (CTRL+3) (Alignmaster) 14 - Start Alignmaster and do a few iterations (APT) 15 - Check PA with the DARV tool (EQmod) 16 - Set Alignment/Sync in EQmod to "Append on Sync" 17 - Do a 3 point alignment 18 - GoTo the target chosen for imaging (APT) 19 - Plate solve, Frame and Sync with my last image of the target (Lacerta MGEN - standalone autoguider) 20 - Start the Autoguider and the Lacerta MGEN PC app which let's me controll the guider from the laptop 21 - Setup the guider 22 - Choose a guiding star, focus and do a calibration (looking for 95%-100% orthogonality) 23 - find the best values for the Number of exposures, Tolerance, Aggressiveness 24 - Backlash - I would like to disable one direction rather than do a backlash compensation but I'm not sure what direction to disable (Last time I disabled the UP direction) 25 - Start guiding (EQmod) 26 - Start to record the PEC in EQmod (I haven't done it before) 27 - When finished - Save and Play the PEC (APT) 28 - Set Dithering for Lacerta Mgen (Distance-12, Mode-Square, Settle time-15, Max time for dithering-60, Start delay-0) 29 - Auto Cancel Exposure - ON: Auto Cancel Distance ???? (I'm not sure what to do here. Last time I had a quick test 60% of the exposures have been stopped even with the distance set to the max of 2.55) 30 - Start Lights plan and when finished 31 - Slew the scope in a vertical position 32 - Start Flats plan and when finshed 33 - Start Bias plan and when finished 34 - Park to Home Position 35 - Power off and go to bed Thanks Emil
  4. When I started taking photos of the moon with my phone I was absolutely shocked of the quality photos you can take with just a mobile phone. I purchaced a bresser mobile phone adapter. That made me go deeper in to astrophotography and invest in a few necesary things to take DSO photos. It doesn't come very cheap but I think it's worth it. Emil
  5. OK, I have tested the newly upgraded light box (bucket) and this is the result. I used AV +2EC to get the entire image mean value close to 25000. Is the histogram in the right place? People are saying it should be at 1/2-2/3. I don't know but something doesn't look right to me. Here is a RAW ISO800 flat frame. The histogram on this one has 2 peaks. And here is a RAW ISO400 flat frame. Emil
  6. Maybe I made myself misunderstood. What I don't know is what option to choose for autoguiding when I set up the eqmod driver. There are 2 options: ST4 and pulse guiding. Which option should I choose when using a standalone autoguider that doesn't connect to the ascom platform? I don't know if there is this option but I'm thinking that maybe I should disable the autoguiding in eqmod if none of the 2 options are good for using a standalone autoguider? Emil
  7. I'm not sure but I don't think PHD2 supports the Lacerta mgen as it's a standalone autoguider.
  8. Hi guys. I have recently decided to try and control my imaging sessions from a laptop. I installed all the software and drivers that I need to do it and done lots of research in how to use them. Because the weather doesnt really allow me to take any proper tests I ran as many simulations as I could to understand how it all works. What I don't know is how to set the autoguiding if I'm using a standalone autoguider. Do I use pulse guiding or do I somehow disable the autoguiding all together? I bought the full version of APT which controls the dithering of the lacerta and with the software that came with the standalone autoguider I can control and setup the guiding from the laptop too. I just don't know what to choose for autoguiding in eqmod when I setup the driver. Emil
  9. I tried on the internet. it didn't work. I downloaded the driver from the Skywatcher support page and Thanks
  10. Hello, Sorry to budge in on this topic but I have a similar problem. I recently bought a USB to RS232 cable from one of the SGL members and I can't make it work. I installed the driver from the CD that came with it and nothing, I tried the one from StevieDvd's link and again nothing. Does anybody have a solution for this? Emil
  11. Hello I'm not sure this is the right place to ask this question but I'm hoping to get some answers here so here it goes. Apparently my autoguider can handle the DEC backlash but I don't really know how to set it up. Here's a screenshot of the manual page. How do I know what direction to disable, when do I disable up or down? Emil
  12. no, I don't have the cable yet.
  13. I have thought of entering 480 sec but I wasn't sure and that's why I went to google. I will soon get the cable to control the mount from the laptop too and I will probably do the PEC trainin with the PECPrep V2.03 But still I don't understand the log data. For example if I take this What do they mean? Is it good, is it bad?
  14. Hi guys. Last night, for the first time I used ATP to control the DSLR and the guiding. I enabled the auto cancel exposure in the hope that I will get some shots with nice round stars but unfortunately most of the exposures were canceled with the "1" value in the Auto Canceling Distance box. I increased it to 2.54 (max) and still half the exposures have been canceled. I downoaded the guiding log from my Lacerta MGEN but I have no idea how to read it and try to correct the guiding. This is the Guiding log. If somebody could please help me understand it. I'm trying to generate a Periodic Error too but I don't know if I'm doing it right. I don't know if 10s is ok for the worm gear period, got it from googling EQ6 worm gear period. By the way, should I do a PEC training before each imagins session? Emil
  15. I took your advice and put the OTA on the mount too. I placed the heater on the eyepiece tray, to have it closer to the mount and OTA. My sw 200p is all wrapped in camping mat , the front has got a cap on and the end is covered with a shower cap. I could get a primary heater to wrap it up around the OTA and keep it nice and worm. When I would start an imaging session I could just turn it off and turn on the recently fitted fan that I installed for fast cooling. As you can see the OTAis nicely wrapped in camping mat.
