    Fireball meteor ?

    I think its just a lens flare from the car (?) passing by.

    Few messier's with 36" scope

    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.
  3. 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.

    NGC7822 - cosmic question mark

    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.

    Messier 81

    Thanks Mike!
  6. 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.
  7. 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.

    Messier 81

    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.

    SHOW US YOUR OBSY

    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).
  10. 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
  11. 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.
  12. 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!
  13. 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.

    M33 - reprocess

    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.

    Cooling issues ASI1600 MM-C

    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.
