  1. Seeing was super steady.   First up is a two piece mosaic with 140 APM, 1.5X Barlow and 183MM camera.

    Data was SO good.....  I redid it at 150%.  Here is my favourite cropped view...  and following that, the upscaled full mosaic.    Mosaic is now 8235 X 8235 pixels.  68MP.  (F16)  Stands up well I think.

    Had some fun with my new camera finally.   Here are two shots that came out very differently.   Colour is very different to deal with!

    First...  2 piece mosaic at Prime with 140/7

    1488292672_2022-02-13-0448_2-U-L-Moon_QHY5III485C_Gain0_Exposure2.6ms_Gamma100(off)_8_lapl4_ap6178_stitch-WV_25-NR1-VCL_1.5_10_1-Edit-4.thumb.jpg.68e6f1f4f5816b341ea1682a09bd079a.jpg

     

    Next is a 6 pc mosaic shot with a 1.5X barlow.

    1571211760_2022-02-12-88p-0457_2-U-L-QHY5III485C_Gain11_Exposure2.6ms_9_lapl4_ap9133-1.6X-6pc-300of2000-WV28-VCL_1.5_10_1-NR1-VCL_3_10_0.3.thumb.jpg.9ebbec5e92cb07b0b06cda754258bed4.jpg

     

    Version 2

    1202219759_2022-02-12-88p-0457_2-U-L-QHY5III485C_Gain11_Exposure2.6ms_9_lapl4_ap9133-1.6X-6pc-300of2000-WV28-VCL_1.5_10_1-NR1-VCL_3_10_0.3-4.thumb.jpg.b7a05e10ffd85970fb3565f4aaaaf1f2.jpg

     

    Last is the only 8 inch shot I did.  Just did the one clip...  scope not acclimated quite yet.  Still OK...  colour was what I was most interested in.    I look forward to more colour hi rez!

    Curious on thoughts.  I find astro colour cams pretty tricky for the moon!   (compared to a DLSR)

  2. Got some sky time last night.  Moon VERY high....  but seeing not optimal.  Good for this scale though!  :)

     

    Capture time from log:

    Start(UT)=043743.247
    Mid(UT)=043844.259
    End(UT)=043945.271
    Duration=122.024s
    Date_format=ddMMyy
    Time_format=HHmmss

    And my first version....  the same file, minus a few tweaks to brighten it.

  3. OK...  only have a little time, but I can help with some basics for you I think.    Your scope is fast...  so you want small pixels.   You want to print presumably full moon shots, so a larger sensor.   I would recommend  a ZWO 183MC  (assuming you want a colour camera).    Here is a screen shot from the website recommended above where I put your scope in and the 183M    And the field of view you will see.   Without a barlow you will capture the whole moon.   This is underampling -   "wasting" aperture in a sense, but totally fine!  We all do it.   Will make a very nice image for printing at larger than 8X10 easy given good data.  (good seeing and capture data and processing)      The smaller field of view shown is what you would capture with a 2X barlow still well inside your "window" of possibility.     You could push a bit more on a good night and get still more details.     If, down the road, you wanted to ramp things up a bit you can try shooting at the higher power and make a mosaic that will print bigger.    Much to learn....  but there ya go.   My 2 cents.  ;)

     

    Edit......   Coma will probably be a factor in trying to make a mosaic.   For full discs NO barlow best.   But,  as well as full discs, you could power things up and reduce your field of view - go for detail shots.  Reducing field of view will speed your camera up - more images in capture =  equals more good seeing frozen and available to stack into better images.  :)))    Clear as mud?   lol    Gotta go!  6yo needs bed.  ;)

    Very nice. I especially like the processing. It looks very natural and the shadows are suitable black - something a lot of people miss.

    Thanks Michael!!   Sometimes those shadows are tough....   they were pretty good here.  :)))  Appreciate the note on processing.....  what I have been really working on!!

     

    Very best

    The terminator is stunning. Hard to belive the scope is only 140mm. Resolution looks much higher than that doesnt it.. Good call hanging on to the data.

    Should be a inspiration to refractor users everywhere

    Thanks so much Neil.   It was our brainstorming that lead to this.  :)))

    Thanks a lot for the suggestions. I will try next time. Although, iso 50 might a bit dark do you just play with the levels/curves to brighten it up later?

    Best to get a good exposure up front .   ....  but,  your settings were ISO200 and 1/400s.    ISO50 and 1/100s is the same signal strength and would look the same exposure wise.    Just better IQ.  ;)

  7. Glad I kept the source data.   After inspiration from brainstorming with Neil,  I completely redid this mosaic from source files.   Quite happy with the details in the terminator.   Thanks Neil!

     

    Be sure to enlarge to the full 30MP image uploaded. ;)

  8. Looks good Kon.  I think you could benefit from stacking a few more frames and dialing your shutter speed down and ISO.    Stacking only 15 frames will still result in some noise at 200 ISO for some cameras.  Go for the cleanest image...  ISO 50 if possible.   1/100 sec plenty good.  I have shot with comparable gear  at 1/50 with good results.

     

    Clear skies!

  9. Truly epic work Neil.   I hope one day to perhaps match this even with a single close up!   All along the terminator is magic.....  I will be returning to this a few times this week to study it more...  and also keep a copy on PC to reference by if you don't mind.

     

    So glad you were rewarded for doing the brute work of getting the big Newt out!!

     

    Clear skies my friend
