Veil

I've been chewing away at this for quite a while now, an eternity in my attention span. I was determined to combine the mosaic in PI as a learning exercise and had been at it, in vain, for a week. I've concluded PI is woeful AND slow at mosaics. In contrast APP knocked over in 5 minutes the bit PI choked and failed on for many hours at a time.

I have a new adoration for the CEM40ec, I threw out 2 subs (for wonky stars) in the whole project, ignoring clouds and other light problems. Floored.

Eon85 + 0.8x reducer
ASI2600MC + SV220 NB filter

2 x 1 Mosaic
360 x 300s (30hrs) 100g -10C 2x Drizzle.

NINA + APP + PI

Not happy with the colour but at this point I'm over it.

Really nice John. That's a hard one, quite low in the sky. I thought it looked like too much sharpening (or deconvolving) but that's just the IIS reduction as the link look real nice!!

Great shot there John! Mate, thought you would do at least an 8-10 panel mosaic...Well done.
I was seriously thinking about many panels with less subs. Not sure on an outcome, just an experiment. Looks fine to me o patient one...

John what a super image, worth every one of those 30 hours plus the hours spent behind the computer to make it happen.

Thanks Chris, I am blessed with pretty dark skies (b3/4) and a relatively reasonable view to the north. I feel my processing lets me down, but I'm not that fussed as I have so much fun doing it.

Cheers Steve. I'm keen to see the results of your experimentation. I was intending to take just the witch's broom but a lack of imagination as to the next target morphed it into a mosaic project. I am doing a 2x2 of the lobster in SHO and the pain (Oh the pain!) has almost cured me of mosaics

Thanks Carl, I must admit the frustration was self inflicted, I knew the answer was APP, just being stubborn.

That’s epic mate great work! Stacks of lovely detail and colours are amazing. Yeah I’m yet to see a better mosaic tool than APP, so easy it almost feels like you’re cheating lol. I’m somewhat into aquiring data on the same target but such a slow process being only above my side fence for an hour or so at a time. You’ve set a very high standard!

Cheers Dave. I tried to get andromeda last year the same way, an hour at a time. After what felt like ages and much frustration I resorted to moving the scope to a better position.

I admire your perseverance, skill and equipment (n+2), John-san :-) I really like these bi-colour targets … kinda looks like the red/green 3D images I used to look at when I was a (much) younger fellow. I reckon your colours superb in both the nebula and star field; lifting the bar mate. I’m learning that getting an hour or two per night on a low northern target is actually quite doable with the ASIAIR’s ‘plan’ function and likely with NINA too. I could never figure it out with Ekos.

Cheers Alex. I'm really enjoying this 'Norther Safari'. I assumed, mainly due to my ignorance, I couldn't get these northern objects. Laughingly, I get that 'mischievous child' feeling each time I grab something less usual, but I'm weird - obviously. I'm surprised you couldn't get ekos to do it, given that's where ZWO stole the ASIAIR software from.
