  1. Past hour
  2. I took the image with a 200mm lens at 1.6" exposures around 200-500 exposures I'm not sure, at iso 1600, they are untracked using a tripod with heavy light pollution
  3. Second to last image of the season. Taken at @wimvb Wims magnificent dark skies, north of Stockholm. The skies are so good (Bortle sky 4) that this image was actually possible. Despite a terrible error in my HEQ5, which made it drift badly in RA, and thus shortening the session to a little more than three hours in total. But I had to throw away some subs because it was evident that they will do more harm than good, and I ended up with one hour of Luminance and half an hour each RGB. While preprocessing I really thought this one will end up unworthy to be worked out and eventually neglected. But I wanted to see if anything can be saved. So I fire up Pixinsight and I processed with straight forward attitude rather than my meditative style of processing (Photons have travled millions of years, you should spend some time getting them right). I think I pulled out what can be pulled from an embarrassingly short session of 2.5 hours. Yet some stuff like the bleaching of color over stars wasn't manageable because of a combination of imprecise focus and the elongated stars caused ny the RA drift. i chose to tone it down although there was some room for more stretching, but this level gave pleasing dynamics, it seemed. Next season will deliver better for sure. Wim have generously allowed me to have a pier besides his at the under construction observatory, and my gear will be controlled through the net, thanks to his expertise. A truly great step in this wild hobby, that I am most thrilled about. No more bad skies in inner city lights, and no more uncomfortable balcony stuff. I will still miss the hustle though.. Any critics are most welcome. Clear skies /Firas
  4. Well I finish work in about 1 hrs so gonna set it up again all charged .Down loaded all that plate solve and apat thingy so let's see how that goes .something else that can cause me grief lol. Hows you got much done ?
  5. Thanks chaps. Just had a quick try out and all seems to be well. I managed a nice split of Algieba at around x100, images merged easily so I think I got away with it! Lucky.
  6. Sounds awful mate.... that must have been some gust of wind! Ive never heard of an NEQ5 being blown over before. To look on the bright side, the 130 isnt an expensive bit of kit to replace and your camera was not damaged. Just think what it would be like to have a nice APO and CCD camera hit the floor!... ouch!
  7. I'm going to try stacking. This means that I've had to change the ROI to exclude ground based lights so that the stacking routine can use stars for alignment. I have reduced exposure to 90s to avoid star trailing. Maybe if I can get a dozen or two frames it might show the hydrogen clouds better. I think the test so far shows promise.

    Hello from Sussex!

    Welcome. Have fun with the forum and the hobby.
  9. Olly Can't agree more, so new friend of mine, when you loaning me that sweet mesu adorned with those lovely Tecs, because you know what they say. Sharing is caring
  10. Hi all I have bought a astro fi 130mm I am having problems aligning with skyportal. I try and align the three stars but every time it fails. I disconnect and realign but it seems to remember, i uninstall the app and still the same problem cam anyone help.?
  11. Welcome. Have lots and lots of fun.

    Hello from Sussex!

    Hi, welcome to SGL
  13. So far it's working for me. Fingers crossed.
  14. Set it up in your living room and get EQmod and PHD2 talking to it without the pressure of trying to image as well. Helped out a mate recently, we set up his mount on my coffee table - it worked with both my EQmod cables (my homebrew one and the homebrew that came with my mount) and steadfastly refused to speak to his £30 one despite the computer finding it. Curiously my Hitect Astro one blew up too (literally, due to poor soldering leaving a stray wire filament).
  15. Exposure increased to 4m. Stars are now trailing.
  16. I wonder how many urban dwellers "with a passion for stargazing, lunar observing, deep-space observing and astrophotography" will want to spend HK$170m on an observatory that in all likelihood will suffer from massive light pollution rather than building one somewhere with dark sky? Particularly in Hong Kong, which is allegedly the most light-polluted city in the world. Shame they don't seem to be aware of the difference between astronomy and astrology, either. That article gives me the impression that it has been designed by someone with a very small amount of knowledge and no understanding whatsoever. But never mind that :) Good luck with your new build. If it goes well perhaps you'll be able to sell it to someone for a knock-down bargain price of HK$160m :) James
  17. I'd have been very happy with the first one. The second looks even better. Very nice. I like the framing too!
  18. If I can improve the cooling on the camera and increase the gain I think this technique may reveal the hydrogen gas clouds (nebulae). I think it possible that directing the warm air from the camera up to the lens may be restricting it and reducing the amount of cooling available. Maybe vent the air straight out and use some other way to stop dew on the lens.
  19. Maybe your PHD2 settings are causing the message when in fact there are stars available. Are you using Star Mass Detection in the Guiding tab? You could try Minimum star HFD (pixels) instead on the same screen. Set to 2 pixels so it doesn't select a hot pixel. Also what camera exposure are you using? Michael
  20. Yes. Definitely. Furthermore, as I wrote, my mount has been modded exactly there.
  21. 3m exposure. Converted from FITS to PNG in PI. I think I may be seeing nebulae in the Milky Way in the bottom of the picture - NW.
  22. Today

    Hello from Sussex!

    Hi and welcome to a great forum, which I feel sure will soon come with suggestions regarding a new mount, always assuming you are in fact asking?
  24. Here's an image converted from FITS to PNG format in PixInsight and contrast increased slightly.
