  1. Hi, Just set up equipment within your pitch area. Hope your first trip goes well. We’ll all need a bit of luck with this weather. I’ll be up in the top corner T320 if anyone passes, with the dob. Hoping to get a better pitch next year if available, I learnt the hard way that a no-show means you lose your pitch for the following year. Rules changed this time it seems
  2. Good idea. Hopefully we’ll get some answers. The Star Party is definitely more than 6 people ! Unless if you look at it as separate bookings at a campsite. I’d be surprised if it goes ahead TBH but really hope it does
  3. any news of Kelling Oct 2020, re the new 6 person rule ?
  4. Sounding OK so far..... tonight looks to be clear, my friend will be up for that (same pitch). I'll be coming up Friday hoping that the weekend forecasts are actually fibbing. Sunday night forecast looks bit better.
  5. I'm hoping to go up Friday (pitch T352, roughly mid/ upper in the Red area) for some visual observing with a dob. Fingers crossed for the forecast improving a bit !
  6. Or use the Sony A7 SLR camera, which has an hdmi video output....
  7. So looks as I thought: modern video astronomy cameras work exclusively via USB and necessitate a laptop to see live images. Stacking requires software. My own preference would be for a mallincam type camera where stacking and basic image improvements can done on the fly, within the camera electronics. Camera goes direct to monitor. As stated these use old CCTV technology, and unfortunately will lag behind modern video cameras using the latest chips etc
  8. I have an old analogue watec which connects direct to a monitor via a composite video-out socket. My monitor can also take HMDI. I have absolutely no interest in using a laptop or capturing digital images. Live viewing is all I want. Am I correct in saying literally all modern digital video astronomy cameras necessitate a laptop these days? Why don't they have at least an HMDI output as well as USB???
  9. Nice report Helix and great to see some more big dob visual action at Kelling ! That night was special. I need to write up what I saw with the 18" Webster. Certainly got my dose of galaxies, using Argo to rapidly tour dozens of NGC galaxies to the South. Was useful to compare and see which ones stand out (many of the small/dim ones look similar). I guess the winner, probably surpassing M51 and its obvious spiral arms, was NGC4565 - so big, filled the field in my 13Ethos. Greatly elongated edge-on shape + dust lane was stunning. Much better than under my normal light polluted skies. Did you se
  10. Yeah, I liked the un-obscured southern horizon. In summer will be possible to delve down into Sagittarius: Lagoon, Trifid and maybe lower still .....Will be murky, but more transparent than houses and trees ;-) That light was SSW; blocking with cars would be dependent on exact location of scopes and risks blocking good areas of the sky nearby? Wonder if the owner is amenable to tweaking its direction (wishful thinking) ?? Re. the approach, maybe driving up the track with side-lights on is OK, till you get near the hard-standing ?....Be good to know the thinking of folks who frequen
  11. Hi folks, just to clarify, I was at Kelling and know of several folks with stuff going missing this time. This was theft, there is no other viable explanation. Lets forget about dogs or stuff blowing away in the wind, or being mislaid, forgetful owners etc. Not great for the victims to hear this....On no previous Kelling that I went to has a single piece of kit gone missing under suspicious circumstances to my knowledge. And our pitch was scoured afterwards. The thief(s) had a propensity to lift low value items which is odd. As Paul suggests, perhaps local kids doing nuisance. Someone with som
  12. That's all very interesting. But instead I will talk about the Watec camera..... Only kidding... good luck with the project. Don't see the attraction myself. The secondary mirror does a very good job of bringing the focal plane out the way of incoming light, so you can put as much clobber there as you wish and its not casting a shadow. Regarding getting rid of the secondary, quoting Suitor: "as long as the obstruction is kept inside that fraction [20-25%], the image closely approximates that of an unobstructed telescope." And a camera might well weigh more than a secondary mirror. I know of s
  13. Seems an obvious gap in the market. The Mallincam Universe has a 1.12" chip (28.4 mm). http://mallincam.tripod.com/id56.html Claims magazine quality images from live view. But no analogue output for a slimmed-down pure "electronically assisted" visual approach.
  14. Talking pure video astronomy (camera analogue output fed direct to AV input of monitor), it seems these vid cameras are based on CCTV units. These typically have small 1/2" or 1/3" chips. Means equilavence to a 6mm eyepiece i.e. narrow field. Contrast that with full blown CCD imaging or dSLR, with their huge chips and big fields. So has no one developed an astro video camera with a big chip ? Mallincam have their "Universe" that does this. But ....that looks more like an imaging decide for me. Only USB output, and laptop is essential... Seems like to get the big field, you are forced down the
