Sweet Ultra sub also sounds nice. I'm still on v1 of the observatory 'building'. I guess mine is more a Mini, than a pico or ultra micro.

Are you using the Atik 314L+ as imaging camera? It's a CCD? Does it do well with shorter exposures? I'm using the ZWO ASI 1600MM-cool with a cmos. When I had everything up and running I was doing 5 min subs. I have just 'fa few days ago' imaged the Crescent nebula with it. Now I sticked to 120 - 180s subs at higher gain, both works well, but I guess more total data is king, so keep at it

Thats very nice. I think I had a DE RMS of 0.65 and a RA RMS of ~1.65, so not as good a yours. This was however with the scope pointing almost at the zenit, and the obsolete orion ssag. I just ordered the ZWO ASI 120mm-s usb3 camera for guiding, so I have big hopes Going to do a full 'computing' upgrade to the obsy too. No more network or raspi / odroid in the obsy, just a embedded ryzen mini pc in the 'house' and a usb3 hub in the obsy.....

I now what you mean. 2018 and 2019 did not produce anything other than a short Ha heart nebula, an a shorter unguided Ha test of the orion nebula. After managing to burn the motordrivers of my avx. 2020 is looking better

Nice going @Gonzo I have never tried a 32min exposiure on my obsy, but I would say you nailed it. Yesterday I got really nice guiding with the internal guider in ekos and my ssag, on the Elephant nebula, when it was almost at the zenith. I have allways had issues guiding with the scope at that rotation, but now it worked. I do However have a crash situation with kstars, so I only get two images, and have to reboot my server to continue. As the orion ssag is in the obsolete folder now, I have taken the hint and otdered a new guidescope 😊 Anyway, nice to see you are still going strong with your obsy!

Managed to get some more data on the Crescent This is now at 4h 14minutes total, with 137minutes Ha and 117minutes O3. I also did a reprocess of this new image. Sharpening up the nebula a bit, and dimming some starts ++ To me it looks a lot better than v1, but I like to hear what you think. /Magnus_e Crescent ngc6888 Ha, Syn, O3 bicolour

It was just going to be a test for when I was waiting for the ElephantTrunkNebula to get a little lower than the Azimuth. My mount has a hard time guiding at that altitude. Now I have more data on the Crescent than the Elephant due to weather. Hope to get more on both, as they are really nice objects.

Thanks Mark, I might just do that. Also for most of the Ha data I would rate my focus a 8/10, while the O3 is a 10/10. If I could add some more 10/10 Ha, then I think it would help

Hi. I have not posted in this forum in a long while. One unguided Ha image of the Orion nebula was all I got for the 2018 and 2019 season, after first managing to burn the motor drivers of my Celestron AVX. 2020 has been good so far. Managing a couple small projects in springtime, and now imaging remotely again. This image could use some more data, but as a 'get back in the game' project, I'm pretty happy. Might do a reprocess later, when I get 'used' to PixInsight after not using it for a while. Image collected with the ASI 1600mmc at -20C using 300 gain, and 50 offset. Total of 3h and 20min, 1h 41min Ha and 1h 39min O3 Pixelmath is 1x Ha for R, 0.8x O3 + 0.2x Ha for G, 1.1x O3 for B Clear Skies

Hi Ian. I use Induino MeteoStation for weather in combination with WounderGroundWeather. Both work with IndiLib https://indilib.org/support/tutorials/177-howto-configure-compile-wire-print-and-assemble-the-induino-meteostation.html The Odroid I use for imaging and the RasPi does most of controll and GPIO. GPIO support on the Odroid is not as good as the raspi. Also, the raspi has only 100mb/s network. I'm lucky that the observatory has a bandwidth of 300mb/s, so I get the images down faster with the Odroid. I use this driver https://indilib.org/support/tutorials/165-diy-auto-indi-telescope-cover.html with my 3d printed dustcap. Works quite well :) https://www.thingiverse.com/thing:2307397

Hi Ian :) I'm happy to see that you found this thread useful. A couple things to add after having some experience using the obsy. 1. I should have figured out how to connect my mount to the 'portable' pier before casting it. I could have saved some cash by using the existing pattern for the pier-plate, and not have to get it customized. 2. I made the height of the pier, the obsy walls and the roof so that the entire mount and scope clears the walls. I did this to have a clear view to the horizon, witch I have never needed or used. I would rather make the obsy wall height and the roof 'height' so that the park position of the mount is less critical. 3. The Orion StarShot Autoguider has issues with INDI. I've been planning to replace it, but have not got around to it. Having a autoguider that calibrates on each try, makes a lot of the 'smart' functions of EKOS work a lot better. For starting with linux, I would just get a copy of Ubuntu and install it on a old PC or Laptop to get familiar with setting up and installing INDI. For later you would most likely like to have it on a raspi, odroid or even a small PC, running just the serverside and no gui, then connect to it from your desktop or so. The goto page to get everything installed https://indilib.org/forum/general/210-howto-building-latest-libindi-ekos.html Having a obsy makes starting an evening of imaging, and ending it later, SO much more enjoyable. No 30 mins to an hour setting up and calibrating, just booting up and done. I have the obsy dry enough, that I keep all the gear in during summer, when it's to bright to image anything. All gear looks good, with very little dust at all.

Here's my best from 2017. More pictures at observatory17b.com Scope SkyWatcher Equinox 80 PRO APO. Camera ZWO ASI 1600mm-cool Baader NB filters, and ZWO LRGB California nebula in Ha. Featured in Norwegian magazine 'Astronomy' in March edition. Leo triplet LRGB. Featured in September edition of 'Astronomy'. Monkeyhead nebula Hubble pallete (SHO). Featured as full page, back cover of 'Astronomy' magazine. 2017 was the most rewarding season for me so far, and first season with observatory. Hope to ceep improving, and hope you like the results

If that is your experiments with a guidecam first time processing mono, then I'm looking forward for things to come

Thanks. The biases and darks I get by closing my remote controlled dust cap I have a A4 led drawing board that I got for flats, but it's not installed yet. It does not turn on when I switch on the powersupply. A button on the board must be pressed, so I have to modify before I will install it. For now I can dither every frame, witch works well. Or I could do sky flats if I get clear skies when twilight. For the price, I have not added all the numbers. It would also be a little confusing as when I order something outside of Norway, I have to add shipping to the price, and then multiply by 1.25x to include taxes. However I have a list of pretty much all items in the obsy! The length of timber purchased I have in a pile of receipts somewhere, and in the cad for the building. // Teleskope / Mount / Accessories SkyWatcher Equinoq 80 PRO APO Celestron AVX Sky Watcher Field Flattener Orion Miniguider 9x50 Orion Star Shot Auto Guider ZWO ASI1600mm-cool ZWO 7x36mm Electronic Filter Wheel ZWO 36mm LRGB Baader HaS2O3 TS 90mm clamps (for telescope) 2x TS Guide rings 34 - 85mm Dovetail + clamshells (for adjustable base for guide rings) SW Dowetail (for teleskope) SW 1.25" LP filter (allready had this, is currently in guide scope) SW Focus motor Shoestring focus motor controller 4" + 2x 2" Dew heater strips Hitec 4 channel dew heater controller // 8" 'portable' pier Dan's pier top plates, 8" pier top for Celestron AVX inc customization (made pier with 4 rods, so needed 4, not 3 holes in plate) 1x wood hobby plate 1200x620x18mm (cut in half and stacked for pier base) 4x steel angles (normally used for shelves, now casted in to center of pier for added sideways stiffness) 1x 8" cardboard casting tube (main pier structure) 4x 1m m20 threaded rods (for stiffening pier, and anchoring) 2x 25kg weber b30 concrete (used ~30kg for pier) 16x m20 nuts (for anchoring pier to base, and piertop to pier) Quick matt black spraypaint Spacked (for pretty pier) // Observatory building 2"3 treated timber (for most of construction) 2"4 treated timber (for strenghtening of roof support) 2"2 treated timber (for roof structure) 1x 2400x1220x15mm OSB board (for floor and main room / electronics seperator wall) 20x angled holeplates (for observatory structure) 10x straight holeplates (for observatory structure) 12x small angled holeplates (stiffening roof) Screws short, long, longest (one big box each) Window rubber seal P (for seal between roof and building) Primed paneling Screws for outdoor panel 11x 2cm tick styrofoam plates (for insulation...) 1x roll of 0.2mm tick vapor barrier (for wather proofing) 4x galvaniced hinges (for roof) Quick matt black spary paint 4x // Observatory technical 2x 100mm ventilation ducts 100mm 240v ventilation fan for wet room 2x 240v wires (for ventilation fan) 2x Gimson Robotics gla600-s long stroke linear actuators, ink bracets and 12v supply Odroid C1+ Odroid case Raspberry Pi 3 Model B Raspberry Pi case SanDisk SDHC 16GB UH (system disk for RasPi) ICY BOX IB-AC611 usb hub (4x output + charge port for powering Raspberry PI) 1x cat6 tp cabel 10m (for internet) 4x cat6 tp cable 1m 1x cat5e tp cable 3m (for dlink camera) Dlink 1Gb/s eco switch Dlink DCS-4701EV outdoors IR IP kamera Linksys PoE Injector (for dlink ip camera) 2x power 'branches' with 6x outputs each outdoor 5m 240v extension cord with 3x outputs 8 kanals usbrelay (for device power and opening, closing roof) wiringbox ip67 (for 8 channel usbrelay) 2 channel usbrelay (for swapping polarization to lin actuators) wiringbox ip67 (for 2 channel usbrelay) 5m dual sided velcro (for cable management) 5m cablecollector 240v exterior push-switch (for manual roof closing) wiringbox ip67 (for push switch) 2x(red, black) 10m 12v 10A wire Looking at the list it's no wonder it took some time to assemble
