  1. Yes...correct. That is why I hate the advert on TV for the lactose free "milk" that uses hedgehogs as it's cast because it only takes someone to miss the crux of the advert (that it is lactose free) to be putting proper milk out for them....totally irresponsible.
  2. Luckily my OH loves hedgehogs so the garden is kept untidy (but neat)....if that makes sense... I did cut a hole in one of the slats at the bottom of the wooden fence in our cul-de-sac to allow them easy access....
  3. Thanks for the comments everyone.... We do put some dried hedgehog food out under the bench inaccessible to cats but I prefer the mealworms as they get eaten by the hogs at night or demolished by the birds the next morning so there is nothing left about for days on end. I always have a bowl of water available for them, which is recommended if you feed them dried food. I once watched a hog that must have come straight out of hibernation drink water for over 5 minutes straight... We have had a few out on occasion and they aren't half noisy, they will sit in the bowl on top of the good to prevent the others getting at the food...
  4. 128 GB SSD PC. Am I Crazy?

    I use a Lenovo Yoga 3 11" netbook with 8GB of RAM and a 128GB SSD, it is fine for my use. An entire night of planetary will be a problem but normal DSO work will be fine. A typical DSO session of mine will be at max about 1 or 2 GB. Just remember to move stuff off it after each session. I keep a single sub of previous sessions so that I can plate solve back to the same part of the sky to continue the session. Remember that Windows will gobble up at least the 28GB with all its various bits and bobs. You could always buy a 256GB memory stick and have it handy (or plugged in the whole time).
  5. I love Hedgehogs and a sure sign of the astro season is hearing them munching on some tasty dried mealworms. I was testing some Bahtinov masks tonight and heard this one, unfortunately he had a few ticks so I removed as many as I could (5 in total), but couldn't get to the one in front of his ear. I used a proper twisty tick remover as instructed by the Hedgehog lady, however removing a tick from a hog is not an easy task, removing 5 is even more tricky. Afterwards I placed him back in the dish and a few minutes later I could hear munching again...usually they scarper for a while. Since it is still a while to go before the cold season I didn't weigh him but I did mark him on his back so I can see if it is the same one visiting (a dollop of nail polish). Other than the few ticks it looked quite healthy but will need to bulk up before Winter. Notice the PIR/Movement sensor, it is used in Winter to see if there are any stray small/underweight Hedgehogs about (that will probably not survive). Full defence mode: Relaxing a bit:
  6. Crescent to Tulip, a reprocess.

    Very impressive Olly....
  7. Forgotten Image - vdB 7, 8 & 9 Region

    Thanks for the comments everyone! Here's a quick LLRGB reprocess. Much happier with this version but still going to do a proper session following "Inside PixInsight" by Keller when I get the chance.
  8. Forgot I gathered data in this region of sky during December 2016. I remember doing a quick process and not liking the result, had the intention of doing a better job...but I totally forgot Baader modified Canon 6D with Canon 500mm f/4 L IS @ f/4. 70 x 5 minute subs of varying quality @ ISO1600 Avalon Instruments M-Zero PHD2 for guiding using QHY5L-II-M camera with QHYCCD miniGuideScope. APT for image acquisition, GOTO++, dithering and plate solving. Data acquired over the 23rd, 26th and 27th of December 2016 just outside Horncastle. Still needs a lot of work...thanks for looking. Will redo following "Inside PixInsight"...
  9. I was reading some posts on FaceBook recently and realised how easy it is for PHD2 guide graphs to look either really bad, or conversely really good if the pixel scale is not set correctly, which is why it is important to post the log files instead of doing just a screen capture. In this image, the pixel scale is incorrectly set to 0.375μm pixel size which shows (incorrectly) fantastic guiding. For this to be true the guide scope would need have a focal length of 1240mm instead of 124mm! And in this image, the only difference is that the pixel scale is correct as the pixel size is set to 3.75μm. (Ignore the peaks in both images, they are caused by dithering.) This is all academic of course because both graphs produce the same image and even at the correct pixel scale and at my focal length (500mm) the final image had pinpoint stars in the corners at 1:1, 100% zoom.
  10. I posted something similar a while ago and totally agree...
  11. Guiding scope

    You asked specifically about the miniGuideScope and I told you my opinion, choice is yours to ignore my or anybody else's advice. I don't know what scope you might buy in the future but it sounds like you really want to buy a 50mm scope instead of a 30mm scope even though you are not sure what difference it will make.
  12. Guiding scope

    I love my QHY miniGuideScope coupled to my QHY5L-II-M camera and would buy another if something happened to it. I like it because it is rigid, small and light and just works. The focal length is 130mm at f/4.3 and coupled with the small pixels and high QE of the QHY5L-II-M camera imaging at 500mm is well good enough. Would easily work up to 1000mm and beyond (as posted above). I think that 50mm guide scopes are usually about 160mm focal length and slightly "faster" at f/3.2 but I'd still choose the miniGuideScope unless I was imaging beyond 1500mm.
  13. July 9th 64-pane solar mosaic

    Top work.
  14. Dithering time wasted?

    As mentioned in other posts above, try to get your dither time down to sub 30 seconds and it won't be much of an issue. At 2 minutes I'd say you would be wasting imaging time.
  15. Dark frame Hypertuning

    @Woodsey65Well lets hope that Darkframe Optics survive longer than IO Astronomy did so that the 2 year guarantee can be honoured if anything does go wrong.
