8th September 2016 25 panel Mosaic

Recommended Posts

This is about as good as I'll be able to get with this Barlow lens and the humidity/heat that we are having in the central part of Arkansas.  I'll be getting ahold of a much higher quality Barlow at some point before the end of the year, probably a 3x or maybe even the 5x(not sure about the 5x on such a small refractor though, and the folks I've been asking apparently want to keep this a secret).....I digress.  If you have suggestions on a 1.25" Barlow in either 3x or 5x....please let me know!


This is the full sized image-should be able to click and go full screen(I think).


Easy....from the ground up!

Battery pack and power source for laptop and mount.
Mount is still my iOptron ZEQ25GT
Optic is the Orion ED80(standard, not the triplet or carbon)
Celestron 2x Barlow with the red filter
Camera is the Imaging Source DMK 21AU618.AS(monochrome)-having to focus through the diagonal to get enough 'travel'(sure that doesn't help the quality)

No polar alignment was done, the Moon....well, it's the Moon.  I set-up really close to where the normal alignment is, and called it good.  After all, the sun was still up.....and the mosquitos were already feeding on me!

Shot twenty-five - 1,000 frame, uncompressed, Y800 videos.
Stacked those 25 videos as a 'batch stack' in AS!2.
Cropped all the 'funny stuff' off in LR2015, and then selected all 25 'photos' to be merged in PS2015.
Completed mosaic was then processed using NikCollection tools and some 'tweaks' in LR2015, border added in Picsas3.

I don't have a suggestion on barlow having only used 2 + 2.5x on lunar thus far but that's a cracker of an image.

One of the best I have seen in a while. Great effort !

Superb mosaic!

I'm hoping to do better, the stacking part went a little 'off'....

very nice indeed.

What scope sis you use?

Do you find red filter works better than IR pass?

Orion ED80

Not sure, as I do not own a IR pass...

How does the 2 + 2.5x work?





Thanks for the kind words, I think I can get something better happening later in the year when the heat/humidity go away.  I hope?!?!?!

Sorry, I meant I've used a 2, and I've used a 2.5, separately. However you've given me ideas. I don't think my OTA will focus/resolve at that magnification but I'll report back when I get the opportunity.

      Second time I undertake this kind of endeavour. Many many movies were shot. Over 300Gb of data. Stitching was done by hand. in adobe Photoshop. 
      Equipment used: 
      CFF 300f//20 cassegrain
      ASI174MM with Astronomik proplanet807
      processing using Autostakkert, lynkeos and adobe photoshop.
      Image is a wee bit too large to add to post direclty. hence just the link.
      Make sure to check out at full res.

      Inspired by Forum Member Xiga, after seeing his fine image of M101 on 22 March 2019, I just couldn't wait to get an image of the Pinwheel Galaxy. 
      My image was taken on 27/03/2019 with my Orion ED80 Refractor and Canon 450D, on my NEQ6Pro mount.
      ( As usual, at present, my images don't have enough hours put into them yet, because I am still figuring out how to plate-solve with APT !
      Once I get plate-solving under my belt, I will start to get more data, hours wise, into my images ).
      My image below is approx 1 hours worth of light subs, composed of a mixture of mainly 70 sec lights, including some 60 sec lights and 40 sec lights, all at 1600ASA.
      I also incorporated 20 darks , 35 bias frames and 35 flat frames.
      Processed through APP and then GIMP.

      Hi everyone,
      A bit of an odd one aspect ratio wise, but fun to put together - first light for my new ASI294MC OSC and technically my first experimental attempt at a mosaic!
      My first stab at using the camera meant I went for 30 second subs, I need to experiment more to settle on my ideal sub length...still, the results are decent for a low integration time of 1.7 hours.
      I love the Orion constellation and if I had the skies and time, I would mosaic the whole thing, but failing that, I can do bits and pieces! Orion's Belt is amazing to me, the three stars, Alnitak, Alnilam and Mintaka, very distinctive in the night sky.
      Full details on Astrobin.
      Thanks for looking!

      Hi everyone!
      The Tadpole Nebula and the Flaming Star Nebula captured over three nights of the unexpected nice weather we had a couple of weeks ago.
      A number of firsts with this image:
      1. My first mosaic - keeping it simple with two panes!
      2. First time I left my imaging rig outside... (I used a telegizmo cover) and it was perfect, allowing me to get imaging very quickly on each night
      3. First time using powerful scripting tools in my capture software, APT, to move to the second pane and starting imaging automatically...worked really well!
      APP was used for pre-processing and stitching the mosaic together, while Pixinsight was used for image processing. A total of 10.9 hours integration time.
      Full details on Astrobin
      Thanks for looking!

      Hi everyone. So I'm looking to do some form of mosaic over the weekend. 
      Is it better to stack in mosaic mode in DSS or merge in photoshop? 
      And is there any other advice for me as this is mainly a learning evening for me so any tips would help. 
      Also do I need just 1 set of calibration frames or a set for each part of the mosaic.
