  1. 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.
  2. 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.
  3. 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.
  4. I think its just a lens flare from the car (?) passing by.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. 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).
  12. 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
  13. 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.
  14. 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!
