Hi Group
I just wanted to thank all of you who joined me last night during my very first black & white (mono) Mallincam video camera broadcast on NSN.
My new MCX2 EXView HAD video camera was used last night for the very first time. I have never used a Mallincam mono (black & white) vide camera before and I am extremely impressed with the sensitivity, resolution, contrast and Sharpness. I used my same scope VRC10" at my usual focal ratio f/3.2. I was using at first an Astronomik UHC for M27, M16 & M17 because of the 52% phase of the moon up high.and later switched to an Orion 7nm Ha filter to try this camera in Hydrogen Alpha.** The Peltier cooler was on full for M27, M16 & M17 but was only at # 6 for NGC 6888 because I was getting some dew issues when I switched the filters**. The transparency was average with 64% humidity.
From my calculations I would say the sensitivity is twice as much as my MCX2 ICX418AKL color video camera and 60% to 70% more sensitive to a MCX2 EXView HAD ICX428 color video camera. The resolution was twice as much when using the Ha filter with this camera compared to my MCX2 ICX418AKL video camera because all pixels are being used rather then just the Magenta and Yellow pixels. I used the miloslick last night and out of the four images posted, I had to only use the amp glow mask on the NGC 6888 Ha image due to the longer 150 sec exposure. This is how we were seeing these images last night live on NSN and NO post processing was applied!
Rock all I can say is thank you very much for this truly amazing camera!! You mention to me that Sony has maintained the sensitivity but lower the amp glow and you are 100% right. I did not even need to use any amp glow mask up to 60 seconds. I do not know how Sony maintained the sensitivity but lowered the amp glow?
For an example of how sensitive this camera is I could not use contrast at 100% like I can with my color MCX2 ICX418AKL camera. Also when I was using the Ha filter on the camera using the same scope and focal ratio f/3.2, it took my 300 seconds on NGC 6888 and last night under very similar conditions same AGC 4 it took me 150 seconds with the Ha filter and the detail is way more, so I will post a side by side comparison. Also when looking at M14 using the Astronomik UHC filter it only took me 20 seconds AGC4 compared to 40 seconds AGC4 with my color MCX2 ICX418 camera. I am predicting that using my IDAS-P2 or Lumicon Deep Sky LP filters which are not as narrow as the UHC filter, the integrations will be at 15 seconds only for M17 and for me here in mag 3.5 to 4 Toronto light pollution skies, I would never have imagined this!
Ken in Australia asked me if I have tried this camera yes without filter and I said no but I truly believe that this camera will be way too sensitive in my skies to go without a LP filter.
Here are the images from last night

**You maybe wondering why did I not get any Ha for M16 & M17? When I changed the filters manually from UHC to Ha after completely powering down the camera and for the 3 minutes for the sensor to stabilize, I turn on the camera and went to full cooling way too fast and developed dew. After setting in Miloslick cooling back to 0 (dew removal) all was well , so I slowly went back to full cooling and dew came back again after trying this several times. I was only able to go to # 6 for the cooler and by that time these nebulas were into my telephone/hydro pole.**
I am really looking forward to using this camera on some really faint DSO's such as Abell, Hickson and PGC galaxies using my IDAS-P2 filter on the next new moon.
Thank you for reading and having a look at my results.
Cheers to all!!
