  1. Sorry if this post is in the wrong section, am not quite sure which subsection of the forum it belongs to, so MODS please move if required. I image in the field with a laptop inside a tent connected to the rig and cameras outside by USB repeater cables, about 20 or so feet away. I will soon be getting a CCD QHY16200A mono with LRGB (Astronomik) and a 3 nm Ha (Chroma) filters. I will need to double check and possibly refocus manually using a focusing mask in between each filter. Rather than disconnect the USB connection to the laptop each time and take it outside the tent to refocus and all the faffing around involved, I was wondering if there is a quicker solution. Is it possible to monitor the ( relatively fast looping) images from the CCD with Nebulosity4 in the Frame and focus mode on the laptop inside, whilst manually adjusting the focuser, and at the same time being able to view the screen image on my Galaxy S7 outside with both devices connected via Bluetooth? I have Googled connecting the two devices with Bluetooth, but it all seems to be about screen imaging the S7 to a laptop/PC or TV and not the other way around.
  2. Sorry to hear the News, the last man on the moon is no longer with us. http://www.bbc.co.uk/news/world-us-canada-38641121
  3. Hi Tony, Please sign me up for all nights, same pitch as the last few years if possible. Cheers, Justyn
  4. Thanks Olly, Will do. I know as a professional scientist that is all about experimenting and finding the best option for the set up you have, just trying to get the best advice I can before starting.
  5. As I have been a very good boy this year, I am in the process of ordering the new QHY16200A J. Only having used the SXVR-M25C CCD before, this will be my first foray into imaging with a Mono and need advice about filter sets. The camera has an internal five position wheel for 2 inch filters. My intention is to get a parfocal LRGB or LRGBC set plus a 7 nm Ha, as my primary interest is in emission nebula. Both Baader and Astronomik have sets within my price range. What are people opinions on which set would be best? Do I really need the Clear filter? I have never seen any mention of them in posted images. Also, is there a quick basic guide to imaging with filters? I would like to get a feel for things as; A) The percentage of exposure time needed for the L & Ha filters compared with the RGB (my main scope is an F 5.3, SW MN190 - moonlight focuser) B) Will I need an LP filter in conjunction with any of the filters other than the Ha? Many Thanks, Justyn
  6. Many thanks for your help. The QHY16 comes with it's own internal filter wheel. I will sill be keeping the M25C and still intend to use it. It is a wonderful OSC CCD.
  7. I am thinking of try my hand at HaRGB imaging and considering getting the new QHY16 which has an ASP-H size sensor (21.6 x 27 mm). I currently use a SW MN190 as the main imaging scope (with an imaging circle about 22 mm) along with a OSC SX M25C which has an APS-C chip, the flats show a very small amount of vignetting in the far corners of the frame which can easily be corrected. I was wondering how much worse the vignetting would be on an APS-H and if it could be simply corrected with flats? If not how much of the frame would be unusable? Does anyone have an example of an image taken through a SW MN190 with a APS-H or full frame sensor?
  8. Some have been known to start off favoring refractors and have then under gone the change to reflectors!!!!
  9. The new QHY16 All in one CCD is being advertised in the USA at $3,999 (although not in stock yet) which should mean it would sell for about the £3000 mark here. That is a lot of camera for the price with an APS-H chip (approx. 21 x 28 mm), and an integrated filter wheel (2 inch filters). One version has WiFi capabilities It might even tempt me into imaging with mono and filters!!!! https://cloudbreakoptics.com/products/16200a-ic16200a http://www.qhyccd.com/IC16200A.html Was anyone here a Beta tester or have any further thoughts/insights about this new CCD?
  10. They tried this in the Brecon Beacons National park and it has not really worked very well. When they were first awarded dark sky status, I phoned the Brecon Beacons National park office and was told that the business model had been done at the University of Glamorgan in Pontypridd (Now Uni of South Wales) ands was all based around amateur astronomers and tourists staying in B&B type accommodation. I told them that what most amateur astronomers would probably prefer would be a campsite with lights turned off and electrical hook up to run equipment etc. They were not interested at all and just reiterated the business model. I think that the Astrocamp and SGL South Wales Group star parties. at two different campsites near Crickhowell and Brecon respectively, bring more astronomers to the area every year than any tourist business model.
  11. There are many different ways including variable star observations, nova and supernova discoveries, near earth objects, new comets and imaging large impacts on the gas giant planets but to name a few.
  12. Here is my picture of the transit of Venus. It was taken with my Galaxy S5 through my friends ED80 with Bader solar film at the Astrocamp star party in May. I normally do DSO imaging and was quite impressed with the results using a smart phone at the eye piece.
  13. Thanks Steve, James and Grant, an interesting intro to CCD technology.
  14. Here is a photo of my lady friend with John Glenn when she worked as a research scientist in the eye department at Ohio State University in the USA. he had come to give a talk about his experiences of managing to put in eye drops for his Glaucoma during his 1998 space shuttle mission.
  15. I am not quite sure if this is either a very bright satellite or a very high flying aircraft. Most satellite trials I get are not as bright as this. What ever it was ruined one of my 15 min subs of the Packman in August.
