  1. Good afternoon, It's been a while (about a decade, give or take) since I've been involved in any 'proper' astro, and I'm slowly getting back in the saddle, again. What have I missed? -Mike
  2. Will this work with a Celestron Nexstar SE handset?
  3. I've had something similar, too and resolved it with a D-Link powered USB 2.0 hub. (It had to be 2.0 as 3.0 played silly buggers with EQMOD).
  4. Hello all, Does anyone have a Skywatcher Star Adventurer kit (and Ball Head Adapter, Wedge, Polarscope and Counterweight) for sale? WHY? Thanks! Mike
  5. I'm interested to know too.. Are you still watching this thread chaps and if so do you still have your 300P flex tubes?
  6. This was done when I lived in Hampshire and I noticed that; * Away from town the light pollution was lower and improved when street lights were dimmed. * In town the white light "glares" significantly more from the existing retro-fitted light fittings. * The light is harder to filter out (all your neodymium-style filters are much less effective).
  7. From these pictures, it seems your mount is doing rather well but it's hard to say... We'd need to see some 100% crops (at near pixel-resolution) and a PHD guiding graph to say.
  8. I get random sparkly bits on my images too. I better check for tinsel and string!
  9. I've decided that I really like PI. The tutorials are great and it's able to align some fairly distorted frames quite well using the 2-D splines alignment algorithm. PI is well worth it, although there's a lot of crossover between the various tools; Maxim, PI, AstroArt, etc. I suppose it all depends on what you're doing and how you work. I'm still using Nebulosity 3 for image acquisition as I really like the easy interface, especially for focusing. What I don't like about Nebulosity 3 is that it's got no interface (and the scripting is a bit hit & miss) for image capture sequencing. I'd quite like to see something like Sequence Generator Pro in there, but for the time being I'm rolling up a sequence in Notepad each time I want to image something. And I forgot to take darks in 2x2 bin, so there are no darks for the RGB portion of this image. Now to figure out how to add the Ha data into the LRGB's red channel to bring out the nebulosity in the galaxy! Thanks for your feedback on the show More to come!
  10. Do give PI a go; I recommend before you trial it (since the trial is very restrictive - i.e. if you install and don't get around to trialling it you don't get another go beyond the first 45 days) that you have at least one tutorial that you like the look of ready to go with your image data. I pretty much followed the LRGB processing tutorial steps/workflow to make this image. I'm glad that you're enjoying the show. There's more episodes to come!
  11. Thanks, the second process is so much better. I used PixInsight which feels to me like a collection of Photoshop Actions on steroids. Even with my non-existent PixInsight skills I was able to produce an image that is better than I could with Photoshop. Although I had to use NoiseNinja afterwards as I don't understand the noise reduction techniques in PixInsight yet. The 2020 Astro podcast is back Episode 17 was out last weekend which is on image processing. Mike
  12. Updated process using PixInsight. I'm still learning, it's a monster of a tool.
  13. Thanks Mr Sulaco, sir. Glad to be of help Pete: Did you find a solution? Was it simply a focus issue? Mine is like each channel is slightly >distorted< - it hasn't been a problem with narrowband but with RGB I'm a bit skewed. I'm wondering if it's focus-related somehow but it probably won't matter for a binned RGB layer if it's blurred a bit. The higher resolution luminance gets the correct amount of each colour so it's worth it in the end. I'm just getting to grips with PixInsight, so I'll post another version up later when I've managed to figure out a slight problem I've got with the LRGB recombination. Cheers, Mike
  14. Thanks Pete, Those halos; it's my alignment. I just can't get a decent alignment of the RGB channels. It's been a problem for me of the last two years - so I'm going to see if PixInsight can do a better job aligning the RGB channels so that there's not a bit of each colour sticking out at various places. A gaussian blur would probably help here too.
  15. Oh yeah, I even left the 2" IDAS LPF on the end of the imaging train - in front of all of the filters. I guess I can probably remove it now and wished I'd remembered to do that before I took this image!
  16. My first image post in how many years..? Finally my nomadic-astronomy existence is settling down and I've found a few minutes to obtain this image. I'm not happy with it at all, but what I am happy with is how good the data is considering there's essentially zero light pollution here, no gradients at all even on extreme stretching. Considering what I was used to from Farnborough, the sky could not be more different. It took me two hours to polar align as I kept aligning on the wrong star. All my astro software appeared to have been out of date and needed updating too. It's amazing how much things move on when you're out of the loop. Anyhow, here's a quick and dirty process of Andromeda just to see what it looks like. I'm fairly new to mono/narrowband processing and I've just aligned everything in Nebulosity 3 and processed in Photoshop. I'm unhappy with the colour of the stars - I didn't blur the RGB layer before sticking luminance on top - and I also forgot to take bias frames in the 2x2 bin too. L = 35x30s + 7x180sR = 6x180sG = 6x180sB = 5x180sThe stacking was done in DSS, and I'm a perturbed that I didn't get the dust lanes to the core of the galaxy like they show on even individual 30 second subs. I've just bought PixInsight (literally ten minutes ago), perhaps there's a tool in there to mask and layer on two luminance layers for HDR processing of bright objects like this?Any critique is warmly appreciated. Be harsh please!
  17. I've just purchased PixInsight.

      Good choice Mike, YouTube has some great tutorials...

      I'm going to need them; the demo had me banging my head on my desk!

      harry page has some great videos and also take a look at Warren Kellers video series which isn't free but covers absolutely everything. best thing i ever did buying PI

  18. Just posted episode 17 of the www.2020astro.com show to iTunes :)

      Splendid Mike, I enjoy these, helps me get to sleep by fighting of my tinnitus , works a treat :D

      I'm glad that my dulcet tones lull you into a false sense of alertness :P

      I was trying to think of that word 'dulcet' but couldn't, isn't that annoying,the older I get the more it happens, of course it could not possibly be related to beer and single malt.

  19. ... well there was this ONE car park ...
  20. I like it Especially the name! Sorry to hear about the light. I hope it gets switched off late at night to save energy? If not, how about getting a shield fitted to it as r3i said?
  21. Top tip: be able to be mobile and the sky is your oyster Sent from my iPhone using Tapatalk
  22. It's not going to be great, to be honest... However you're in a great location for travelling a few miles north or south to some much darker skies 20-30 minutes in the car to the south around Alton and the skies will be significantly darker.
