  1. I agree that the humidity is quite hing. We have improved ventilation recently but so far nothing has changed. It hasnt been issue to any equipment because they are warmer when turned on than air around them. They dont seem to collect moisture at all. Same cant be said about our walls though.
  2. Ive been collecting bits and pieces to upgrade my setup and its finally coming together! I built a power distribution box that is attached on top of the telescope to minimize cables that come down from the scope. Only thing that is going up from the pier to the scope is one USB 3.0 cable and power cable. Inside the box is 8 chanel usb relay to unplug equipment remotely and fuses to every power outlet so in case of a short circuit I hopefully only blow a fuse. Startech USB 3.0 hub is attached on top of the DIY power distribution box. The scope itself is SkyWatcher Esprit 100mm optimized by Teleskop-Austria, it is paired with Starlight Xpress 7x36mm filter wheel, USB_Focus V3 and ASI1600MM-C. For guiding Im using ASI120MC with a finder guider. Also I sold my old HEQ5 to make room for EQ6 which is more suitable for this scope. I cant wait to get my first light with it.
  3. Final image of the season for me, for the first time our roof actually got stuck. Thankfully it was closed during the time. There was one loose wire that caused power loss to the roof motor, it took me 4 hours to fix it because there was alot of wiring to go though with a multimeter to sort the issue. Now it is fixed and ready for autumn season. Details in Astrobin: For next year I will upgrade my dslr lens to a telescope and mount from HEQ5 to EQ6 to get longer focal lenght. Thinking of getting SW Esprit 100mm because it is very sharp and doesnt require any collimation. Also I will ditch my laptop and build a better pc for the purpose. Biggest need is definedly wake-on-lan which isnt an option in BIOS in my current setup.
  4. Our observatory now has weather camera installed outside. Previously this was inside the observatory so we had to open the roof to see the sky. We installed the camera in the autumn but stumbled on USB problems that we couldnt solve. Solution was to use completely separate PC to avoid problems. I happened to have LattePanda and now its used to monitor the weather and to act as a backup camera for our indoor camera in case there is a software issue in my imaging laptop or the camera itself fails for some reason. Its unlikely but since I had webcam laying around aswell - why not? :) Also I plugged in my Stickstation to the LattePanda to get temperature / humidity data. I dont want to move my telescope when it gets below -25C to avoid breaking cables or gears in the mount. Now its easy to check what the weather is like. BTW, does anyone know a good lens that would give allsky (circular) view with ASI120MM? We might upgrade the lens in the future to get more FoV. It doesnt have to be super sharp since plexiglass infront of the lens will affect image quality anyways.
  5. Thank you! Yes we do get alot of snow here, it depends on the climate (this year has been extremely warm so most have melted away) but around 60-90cm per year. We are using heater cables on the rails to melt the snow off our rails so the roof can open smoothly. However snow can be quite heavy so to prevent our roof motor from stalling we are using remote controlled human with a shovel to clean the roof every once in a while. Very hing tech solution!
  6. Lately weather has been co-operating and thanks to three clear nights in a row Ive had plenty of data to process. Here is some new projects and some that Ive reprocessed or added OIII and SII channels to monochrome images. Simeis 147, now in color. This is my longest project so far with 24 hours of exposure time. SII channel is suprisingly strong in this target, but OIII is very faint. IC1318 and NGC6888 Orions belt NGC2237, Rosette nebula NGC7000, North America Nebula Reprocessed IC405
  7. Thank you all for your kind comments. :) Erik lives ~300 kilometers and I live ~150 kilometers away from the observatory. So yes, its quite far away. We both were sceptical about everything and tried to do as much fail safe solutions as we can, while keeping the mechanism and electronics as simple as possible. Carole: The main dome is west of our observatory, it only takes ~10 degrees above the tree line so its not a big deal at all. Here is my latest image, Auriga region in SHO palette. This is my first SHO processing. Ha 79x180s, OIII 72x180s, SII 70x180s. Total integration time little over 11 hours, I might need more Ha because some of it is very faint.
  8. Here is some images Ive shot recently, as Im typing this both of our telescopes are at work. Its 3rd clear night in a row! Heart and soul nebula, two panel mosaic. Total exposure time is 22 hours (11 hours of Ha and 11 hours of OIII, 180s subs). I think I could improve my processing but for now Im quite happy with it. This is my latest project, Simeis 147 also known as Sh2-240. 16 hours of H-alpha (320x180s). I might shoot some O3 and S2 to get coloured version later.
  9. Hi, me and my friend have been working on this project for about 8 months now. Thought I would share it with this community aswell. Nicknamed "Castle of clouds" -our observatory is located in Varkaus, Finland. Its built in the vicinity of Taurus Hill Observatory (our local astronomy club owns the land but we had a chance to rent a piece of it). We chose this place for our project mainly because everything from electrical grid to internet (and sauna!) had already been built there and it was easily accesible. Light pollution on the site is next to none (Borttle 3), SQM reading from lightpollutionmap.info is 21.83. Our observatory is fully automated and can be opened remotely with a DIY USB relay control. The same control system also can switch on infrared LED lights for our security cameras and turn on two flat panels. For moving the roof we are using garage door motor with bicycle chain. The chain is attached to a set of heavy duty springs that soften the start. Motor stops automatically when limit switch is hit by spring loaded metal rod. This prevents limit switches from breaking when roof touches them. Inside of our observatory there is two telescopes, mine is very wide field narrowband imaging setup. Im using HEQ5, ZWO ASI1600MM-C, QHYCFW3S -filter wheel with Baader 36mm filters, Canon EF 70-200mm f/4L USM. Focusing is done with USB Focus V3. The other telescope is my friends 6" f/4 Newton with ASI1600MM-C and EFW on EQ6. This setup is autoguided with guidescope. Mine doesnt need it with only 135mm focal lenght. Because our observatory is fully remote, we ensured power to the telescopes and PC's with UPS. Its protected from the cold with insulated box and a small heater that keeps inside temperature at 5°C. A small battery powers the roof so we can always close it if there is a power outage. Inside the gray box is all of the control electronics, fuses, etc. for every device. Also we placed ASI120MM inside so we can monitor the weather and shoot timelapses etc. Focus is a bit off though, will fix that soon. UPS is underneath the control electronics inside that wooden box. Also lately we installed heater cables to melt snow and ice off of our rails. Roof opening. View from the "almost all sky" -camera. We have had alot of clouds lately, but here is my first light. 52x180s H-alpha. Planning to do a narrowband mosaic with Sh2-129.
  10. I think its just a lens flare from the car (?) passing by.
  11. I do get to use it few times a year. If you see other post Ive made to this forum there is plenty of observations done with it. For example, M42, M57 and Cat's Eye nebula all show colours. M42 appears to me as purple / blue. M57 is clearly turquoise with reddish outer parts. Cat's Eye seems slightly blue to me. Here is picture of the scope itself. It has two secondary mirrors to keep the eyepiece closer to the ground. As a finder there is 100mm refractor. Thanks laudropb. Not ideal in terms of sky quality but as always, alot of fun.
  12. Hi, I observed these during amateur astronomer meeting at Tähtikallio observatory (in Finland) with 36" f/3.5 Newtonian. Lovely weather, although sky wasnt as dark as usually due to hing moisture content in the air so I didnt try to observe more Hickson groups. Instead I sketched few globular cluster's and bright galaxies, all of them listed in the Messier catalog. M10 and M12 were really beautiful although they were really low near the horizon.
  13. Thanks everyone! I will definedly do more widefield imaging in the future, just have to get rid of tilt in my T2 to EF lens adapter before doing more.
  14. Hi! I tried to do some widefield imaging for a change. 25x600s h-alpha with ASI1600MM-C and Canon EF 70-200mm f/4L (135mm). I piggybacked them on Taurus Hill Observatory's Paramount ME mark I. Luckily the main scope has free vixen dovetail bar on top of it so it was easy to attach. Also I replaced my laptop with much smaller imaging PC (LattePanda), it worked really well with SGP which suprised me because its so small. I will definedly use it more in the future for grab and go systems. To me NGC7822 looks like a question mark.
  15. Hi, although Ive been doing lots of deep sky imaging Ive not really done any serious lunar imaging at all. Here is my first try with ASI1600MM-C and 12" f/10 Meade SCT on EQ8. I took 4 panels with 850nm IR pass filter, 20 frames stacked in each panel out of 500. Image is quite large, at 1:2 scale out of the original. There is plenty of intresting details around Mare Crisium. Unfortunately seeing wasnt stable enough the top panel would be as sharp as the rest is. Still Im quite happy with the results. C&C welcome.
  16. Taken at Taurus Hill Observatory 5th of February with 16" f/8 SCT and SBIG STT8300M on Paramount ME mark I. L 6x600s, R 1x600s, G 1x600s, B 1x600s = total exposure time 1.5 hours. Clouds rolled in faster than expected, but this came out OK after all. Seeing wasnt really good, so its bit blurry.
  17. Here is mine. 6" f/2.8 Boren Simon newtonian on HEQ5, ASI1600MM-C, Starlight Xpress 5x2" filterwheel with LRGB / or narrowband filters, focusing done with USB focus V3. Guiding with 50mm finder and ASI120MM. As allsky camera I use ASI120MC which you can see on the left inside the plastic dome. On the right, aluminium box that contains remote-controllable flat field panel. The telescope is remote-controlled from indoors, only thing I need to do manually is open the roof and hook up batteries since I dont have electricity here (except generator to charge laptops and run working-lights if needed).
  18. Hi skybadger, its V0416 UMa. Approx. 14-15 magnitude, its close to Mizar. You can see more information on AAVSO website: http://www.aavso.org/vsx/index.php?view=detail.top&oid=159294
  19. Thank you! Im still learning photometry, but results are starting to get better. I wish I could somehow make rough estimate of the asteroids shape based on the light curve. Maybe some day Ill figure out how.
  20. Hi, after almost 2 months of clouds there was finally a clear night in sight. I made most of it, imaging until clouds rolled in about 4 in the morning. I shot these using two telescopes at Taurus Hill Observatory. Its fun to operate two at the same time, luckily its possible from indoors. Ill also attach here light curve of variable star V0416 UMa that I made during the same night with C14 and SBIG ST-8 on Paramount ME mark II. Other images are taken with 16" f/8 Meade SCT and SBIG STT8300M on Paramount ME mark I. Im expecially happy with Dembowska, I tried to get complete light curve twice in 2017 but clouds or fog always ruined my photometry. Milkyway was also beautiful as always, I spent some time outdoors just looking at it while telescopes clicked more subs. Worth every second in the cold, windy night!
  21. Hi! Does anyone here use ASI174 for all sky camera - what lens youre using? Im planning to install one I have (174MM-C) on my balcony, but I cant find suitable lens for it. I tried the one that comes with ASI120, but sensor is too deep in the camera to reach focus at infinity. I do have adapter to mount Canon EF or M42 lenses to my camera, however I would like to use physically smaller lens - Im looking for wide angle or fisheye. It doesnt have to cover all sky since my view is very limited (approx FoV 45 degrees horizontal and 80 degrees vertical). Do any of the C or CS mount lenses focus at infinity with my camera? Backfocus distance is approx. 17.5mm.
  22. Hi, I reprocessed some old data captured 2.10.2016 using new arcsinhStretch in PixInSight. I have some h-alpha data too, but for this version I only used LRGB to avoid reddish hue that I cant get rid of if I use my H-alpha too to blend in with my red channel. L 23x180s + R/G/B 7x180s, total exposure time 132 minutes. C&C welcome.
  23. Your ambient temperature is too hing for your camera. Try cooling it less (use max 80-90% of the power to make sure it has some power to spare if ambient temperature rises). Camera is supposed to get hot, heat from the sensor has to go somewhere.
  24. Imaging season has started for autumn 2017! Here is first images taken last night. Also I took quick milkyway picture with dslr and 8mm samyang. No tracking or anything special, there is some light pollution in the horizon but otherwise looking good. Little under 2 hours of exposure time on both images (34x180s and 36x180s). For IC1318 I wouldnt have needed so much, but I didnt have any other targets for that night. More exposure time certainly wont hurt though. -V
