  1. Thanks for doing this comparison MarsG76 I am really interested in the practical improvements when compared to the theoretical advantages of the monochrome camera. I've never been quite sure of the QE of the Canon 700D at Ha wavelength either before or after modding except it improves the results dramatically compared to my unmodded Canon 600D which is all but useless for imaging DSO's under the light polluted conditions here. I still think the quantum efficiency at Ha wavelength for the ASI2600MM is low (compare the ASI294MM at around 76% at that wavelength and the older ASI183MM is around 78
  2. Hi Mars G76, thanks for starting this thread. It will be fascinating to see your future comparisons of images between the two set up’s. The difference between theory and practice-lovely. I have been viewing the ASI2600MM as a potential future replacement for my modified Canon 700D for wide field nebula work. The peak 91% QE isn't perhaps where you would wish it on the monochrome sensor, the graph below is from the FLO site for the ASI2600MM-Pro USB 3.0 At the Ha wavelength the QE drops to the mid-upper 50's, ok the OIII and Hb are much higher but the SII is even lower t
  3. Well I'm making a personal stand. No more astro-purchases for a year then see where everything still resides. We are all going to have to repay the enormous costs arising from the virus so saving some hard earnt notes in the bank will come in handy. Difficult times. Cheers, Steve
  4. Hi thanks for posting. I will be very interested to see your final result using the filter with the modified 600D in the light polluted environment that is Nottingham 'Queen of the Midlands'. Quite understand your wish to try out the filter and we have had a terribly long wait for any clear sky since the beginning of November 2020, pity it coincides with a waxing and full Moon but there you go. M42's brightness will try to break through some of the light pollution. Interested on a side note-how you are faring with the IDAS (LPS) D2 filter under your conditions? Cheers, Steve
  5. Here is the video from the Astro Imaging Channel with the appearance of Thomas Branwell mention in my last post. hope you find it generally informative. Cheers, Steve
  6. A very lovely image full of detail, colour and dust lanes. The various nebulosities have created a 3D effect in the detail. Well done. Cheers, Steve
  7. More than happy to oblige. Now it's up to the weather! Cheers, Stede
  8. Great stuff, keep recording. I've been keeping a manual record of nights allowing me to get outside and either observe or image for a number of years which I posted in anothanother SGL thread (copy below). The problem is one man's observing session can be different to the next and imaging planetary taking less time than for DSO work. So far January was rubbish, clear nights with the waxing Moon up. Also location will affect records. Recently I've been keeping an eye on a Weather and Radar App on my tablet which so far has been very precise in allowing self forecasting for cloud, far super
  9. From what I've gleaned the satellites have a harder time picking up the blue peak from led lighting and which might explain why my location shows such a drop over the years. Still worthwhile have recourse to the site. Also some of the peak outliers may be down to snow cover at the right times of the year. Cheers, Steve
  10. Just make sure your guiding software or device is compatible with the guiding camera you are to use. Cheers, Steve
  11. Yes, I hope you enjoy using it. I was quite surprised at the trend for around here showing a decrease in radiance picked up by satellites. It will be useful for keeping a watch on radiance as we are having a number of housing developments locally. Cheers, Steve
  12. I thought I'd share this very interesting site with other SGL members- https://lighttrends.lightpollutionmap.info/#zoom=9&lon=0.02131&lat=52.58884 It enables users to create a trend graph showing radiance levels in a specified area across 2013-2020. I've found that choosing the map grid, monchrome setting and adjusting the opacity of the Lights layer from the pull down menu on the right jand side allows you to see the area underneath more easily. By clicking on the fourth icon on the left side you can create the points for the area you want to see. I've been inputting m
  13. Hi, some miscellaneous PLL items to make more widely known to owners of the Eagle Core. Status update. The Eagle Core updates currently remains at v2.10. The Astro Imaging Chanel on YouTube will be having Thomas Branwell the North American Director of Operations for PrimaLuce Labs live on the 15th February 2021. Interesting to see any coverage on the Eagle Core, and developments or on accessories and the recent Eagle4 product range of control devices. I've also come across this podcast on Thomas' journey into amateur astronomy and his move from Apple to PLL. Interesting backgro
