Very nice...I haven't tried mosaics with my ASIAIR Plus so far. Your video gives me great inspiration to try it in the coming season. Excellent info in the video!!
Excellent, thanks for taking the time to comment. I’ll be doing a video this week covering the processing of this image to complete the journey. For mosaics all you need is patience and clear skies. And maybe some tears. 😂
Thank you so much for this great video, I have a big question, how do you stick the 4 panels together ? or it wil be done by the Asiair ??? I will centanly need to put them together before star processing, otherwise I would never achieve consistance color and exposure in the four panels.
I’m about to start my first mosaic project tonight- a 3x4 mosaic covering Rho Ophiuchi and the Blue Horsehead with 3 hours on each panel. I hope that is not too ambitious and also that 15% overlap is enough. I saw that you mentioned cropping out the dithering edges before merging. I will end up with over 1,500 sub exposures, so how would I do that without manually loading up each one to crop? That sounds extremely tedious no matter what. I don’t have PixInsight, so I use DeepSkyStacker and Photoshop.
To calibrate and stack my subs, these days I use PixInsight's Weighted Batch Pre Processor script (WBPP), it's a little slower than Deep Sky Stacker (DSS), but runs on Mac where as DSS doesn't. I can put together a short video showing this and add it to the series perhaps?
@@astrojourneyuk thanks for your prompt reply! Yes, If you could upload a quick demo on how you calibrate those individual panels and transform them to one single photo, that would be greatly appreciated. Thanks again!
You should definitely give it a go at least once. I'm really glad I tried again because I love the result second time round. Funny you should say about how I did the processing. I'll be releasing another video hopefully over the weekend on the processing of this image, step by step in PixInsight from stacking to final result!
Many thanks! At 8:01 you say the blue box is where the scopes currently pointing. Is that blue box based on the real orientation if the sensor, ie did the ASIAir take a shot so that it knows the sensor orientation? That’s the one area where I still have not quite got it, ie how to make sure your camera sensor orientation is correct. Many thanks!
I can’t remember 100% off the top of my head, however, before doing the mosaic use the rotation feature in the sky atlas when in Preview mode (I think, I’m on a train currently) and it will take an image, platesolve and confirm the orientation at that point. Then you can get it right and do the mosaic from there.
I dither always. There also needs to be a good overlap between the panels which means dithering won’t impact things. Just crop out the dithering edges before merging.

Nicely done! Cheers!

Nicely done - clear sky tonight - Going to give the same target a go! Thank you!
I just keep getting teased with an hour of clear sky. 😭😭😭 Good luck!

Amazing!
Thanks.
Great video - awaiting my new gear to start AP so will def put this in my plan (once I know what the hell I am doing lol)
I definitely recommend getting good at single images and processing those until you move to mosaics. They can be tough.

Thanks for that helpful video. What program do you use to join or stich those mosaics together. TIA
It is PixInsight and I think it’s the video that follows on from this one.
@@astrojourneyuk Thanks Mate, keep up the good work. Clear skies 😄 in the UK 🤣😭😭. Seriously Thanks 😃
No problem.
Thanks for this informative video! Can you show us how you stack those panels please? Thanks!

Can you describe how you go back for night 2,3,4,etc? How does the ASIAir find the old panel position?
Once you have everything in the plan all you need to do on subsequent nights is start the plan again. The plan will stay there until you delete it.
Cool! I’d like to give a mosaic a go sometime. Did you do the stitching using the tools in PixInsight? That would be a good video tutorial.

Can you dither when shooting a mosaic?
I dither always. There also needs to be a good overlap between the panels which means dithering won’t impact things. Just crop out the dithering edges before merging.
gain 111 is a psychological thing or it's really the sweet spot?:D
Gain 111 should be the "unity gain" for this camera. So, it is the sweet spot to balance gain and noise.
