First light for the ASI1600MM

Recommended Posts

Hi guys

 

well the ZWO ASI 1600MM finally arrived  ( after the postal system sat on it for 3 days :(  )

I did some comparisons between it and my ZWO ASI 178MC that had been the main solar cam up till today

both using my Lunt LS60THa and a B1200 (12mm) blocking filter

 

these first two are unprocessed ( SOOC ) , just resized for the forum

and ALL images are single frame only ( no stacking)

firstly ... the ASI 178MC using mono mode in SharpCap

Now the ASI 1600MM

NOTE:, tho the image from the 178MC looks more detailed. Strong brightness variation can be seen across the image compared to the 1600MM

What I discovered in processing was that the 1600MM image processed so much better and resulted in a significant increase in finer details  :)

ASI1600 processed ....

There isn't really any comparison between the two ..... the ASI1600 shows much better detail. Specially seen around the Active Region

Next post .... prominences

now some limb/prominences

Ohhh golly gosh !!!

again, these first two are unprocessed ( SOOC ) , just resized for the forum

The limb and prominences are just so much sharper for the 1600MM

 

The 1600MM with a little processing

The ASI 1600MM seems to have a better dynamic range ( well I would expect it to ;) )

it is easier to pull out prominences and still have a non- overexposed surface

please excuse the poor editing blotchiness in the dark area around the outside of the sun ( I don't claim to be the world's best editor ;) )

great shots mate, deff a step up with the new cam. well done. charl.

Thankyou

Yes, look forward to some decent active regions in the future to see the good detail in them :)

your welcome mate, where due for some action soon, its been ages since we had a large sunspot, think this was the last large one we had back in September. charl.

WOW ... look at that detail

 

I am still learning and playing with Registax etc to get better results

Nice comparisons, Dave.  Thanks for taking the time to share 'em.

What scope(s) did you use with those?

I should have stated :rolleyes2:

the Lunt LS60THa

 

Just about to post a new thread .... there's a huge prom. visible this morning

      I spent the full night out last night and got 6 hours of Ha lights on the Bubble and the Horsehead. Reasonably pleased with the results, but even though I followed my usual process and got good focus statistics in APT, I am slightly out of focus with roundy stars and some are even slightly donutty. Samples are attached below.
      Problem:
      - After getting close to spot-on focus, the APT Bahtinov Aid showed a focus distance oscillating from -0.02 to +0.02. Seeing seemed good to the inexpert eye. Not so sure about transparency as there was some thin, wispy cloud throughout the night. So, I started the night's imaging with focus 'Close' rather than 'On' focus.
      - Different subs show different quality stars, ranging from small donuts to circles.
      Background information:
      - HEQ5 Pro Rowan; SW Esprit 80 with field flattener, SW stock manual Crayford focuser; ZWO EFW Mini; Baader 1.25" 3.5nm Ha filter; ZWO ASI1600MM Pro binned 1x1 @ -20c.
      - AA Starwave 50mm guidescope with ZWO ASI290mm Mini guidecam binned 2x2.
      - All subs are 300s, gain 139, offset 10.
      - Polar alignment with Sharpcap to 17 arcsec ("Excellent"); capture with APT; guiding with Phd2. Focus with Bahtinov mask and APT Bahtinov Aid. Stacked in DSS with Darks, Flats and Dark Flats.
      - Mount is well balanced in RA, but is very camera-heavy in Dec.
      - PHD2 guiding was around 2"/px. Imaging pixel scale is 1.9"/px.
      Questions:
      - Do I put the round stars down to seeing, given that the Bahtinov Aid focus distance was bouncing equally above and below zero?
      - Can poor seeing cause the donut stars?
      - Would an electronic auto-focuser do any better in this situation?
      - Would the Seeing Monitor in Sharpcap give useful information? I didn't think to use it last night.
      - Could my guiding performance, and possibly the Dec balance, have affected the image quality in this way?
      - What are my options in future - abandon imaging for the night? Bin all images in software 2x2 or 4x4 to sharpen the stars at the expense of lower resolution?
      - Other suggestions?
      Sample 1: Detail from a single 5-min sub of Bubble nebula at 100% showing round stars, and a blurred bubble.

      Sample 2: Detail from a different sub of the Bubble nebula at 400% showing donuts

       
      Sample 3: Detail from a 5-min sub of the Horsehead nebula at 100%, showing both round and donut stars

       
      Finally, both images stacked, calibrated and stretched, scaled to 4x4 in Gimp. 28x300s Ha on bubble, 22*300s Ha on horsehead.

      Hi,
      I would like to share with you an article written by me on high-resolution solar imaging in different wavelengths.  Glad that the European Physics Journal (EPJ) Web of Conferences published it. You can read it at:   

      https://www.epj-conferences.org/articles/epjconf/abs/2020/16/epjconf_seaan2020_01002/epjconf_seaan2020_01002.html
      You can see the different layers of the Sun in high-resolution images using different setups.  
       
      Best regards.

      How can I set up APT so that it always connects by default to my imaging camera? I have an irritating problem that APT will regularly connect to my guide camera, even though that camera is already connected in Phd2.
      I have created two APT shortcuts on the desktop, one specifying camera 2 (which usually is the guidecam) and the other specifying camera 1 (which is usually the imaging camera), but it looks like cameras 1 and 2 are not absolutely assigned to the ASI1600mm (imaging) and ASI290MC (guiding).
      At APT startup, in the log it will say 'Connected to ASI1600mm' and then imediately say 'sensor size 5.6mmx3.2mm'. Then I know I have a problem as it's obviously not the 1600! I can usually sort it out by disconnecting, Shift-Connecting (to get the camera selection dialog), and selecting cameras 1 and 2 until I get the correct sensor size.
      There must be a better way?

      Hi All,
      Im looking for preloved zwo asi 183mm Pro or 1600mm Pro and a zwo 8x1.25 inch EFW. Let me know if you have anything suitable. 

      Many Thanks,
      Ronan
