  1. Sad News Hope they catch the person responsible, and get the kit back....

    BBC Stargazing Live - My thoughts

    Now thats something interesting that was debated last year. Paul Vanezis, one of the producers pointed out that there are 2 meanings - live stargazing where we look up at the stars (clouds), or a live programme about stargazing... It is for the latter that the programme is called Stargazing live - its a live programme about stargazing.... On the point that they didn't visit us out in the field at Jodrell Bank that was made earlier. I was there on Tuesday night, and the reason they didn't spend much time out with us was simply that everyone was expecting it to cloud over. We were all very shocked that it stayed clear throughout the shows! The producers made a judgement call on the running order based upon the likelyhood of clear skies which meant they didn't come out and visit the amateurs. They did tell us that before the show went out. Cheers, Richie

    BBC Stargazing Live - My thoughts

    A very good point Robin! We should all be watching eBay for the next couple of months - I suspect there will be several bargains to be had! My view is that the programmes were fun - they tried to explain some very difficult concepts, and did a good job at it. I do think they tried to squash a little too much into to little time though. My opinion is that it doesn't matter if we like or dislike the programmes - if the general public gets something out of it and gets turned onto the sky, then brilliant. Cheers, Richie

    Photometry Intro?

    Hi Merlin, Thanks for the info - luckily I use a Monochrome camera (the SXVR-H18) - Can you tell me what BVIR actually means? Cheers, Richie

    Photometry Intro?

    Hi, Thanks for the info. I use MaximDL - i've had a play with the astrometry stuff, but my check stars are not coming out at the right mag value. Not sure what I am doing wrong! I guess just a light curve for a first pass would be nice, although having a calibrated system sounds like the way forward - is there a set of standard calibration stars that I should use? Cheers, Richie
  6. Hi All, With the appearance of SN2011by, I really would like to use my equipment to do some real science and learn how to monitor the brightness of the outburst over time. I currently have various scopes, and an SXVR-H18. Normally, when taking deep-sky shots, I pick a relatively long exposure (say 5 minutes) and take lots. I am wondering how different things are for photometry. Specifically, as the H18 has anti-blooming gates, and a relatively shallow well depth, I guess it is critical to keep the exposure length shorter so that the chip doesn't become saturated? The full specs on the chip for the H18 are here: Starlight XPress SXV series cameras Page Also, do you still need to shoot mulitple exposures and stack? I am guessing that raw frames (no calibration) should be used as well? Any advice gratefully recieved on how to get the most accurate results out of this sort of kit. Thanks in advance, Richie

    Astronomik vs Baader Filters....

    Actually Olly, that is exactly the sort of observation I was after... the baaders are soooo much cheaper that I can get an Oiii as well, so if they are good enough, and work well, then thats my preferred route..... Sent from my Milestone using Tapatalk

  9. Hi All, I am just about to buy some 2" filters to replace my old 12nm Astronomik 1.25" filters and LRGB set. I can't afford the Astrodon's, so that really leaves me with Astronomik or Baader. Can anyone tell me relative experiences of both, to help me narrow down on a decision? I am going to be buying an LRGB set plus as narrow an Ha filter as I can (7nm for Baader, 6nm for Astronomik.) Any thoughts/advice gratefully received! Cheers, Richie

    Second Light SXVR-H18 - Crescent Nebula

    I have the external fan - it was holding -40 ok for me until last week... Now I am using -35. Aye Rob - it is a noisy [removed word] indeed, but does work Cheers, Richie

    Brian Cox is on Radio 2 tomorrow morning

    Cool - i'll have a listen - thanks for the heads-up!
  13. Hi All, Mark Thompson (the One Show/Stargazing Live Astronomer) just pinged me and asked if I had/knew anyone up north (Northumberland and above.) From Mark: "Calling astronomers of the north..... As part of my piece on the One Show tonight (BBC1 between 7 and 7.30pm) I will be talking light pollution. I am looking for examples of good dark sites that can be represented by a good picture of the night sky. (Ideally showing foreground objects but not essential) I have pics from South England and East England so anything from Wales, North West, Scotland would be fantastic. If your pic gets shown, you will get a mention too. Please post on this thread (I am going to link him to this thread), and email the original to mark@markthompsonastronomy.com" Many thanks all, Richie

    NGC281 - Pacman in HST Palette...

    It must have remembered the photons then Olly! Hehehe This is a slight crop, as the H18 picks up some strangeness (crescent shaped stars) to the top-right of the image. Must post about that actually.... Anyway, wcs. I found it recognised my webcam without issues, however, I did have to tweak the settings from its default of 320x240 to 640x480., otherwise it wouldn't work. What webcam are you using Olly? Cheers, Richie
