Honestly I just use Nina flat wizard atm. I was a bit concerned when it went from my broadband 0.2secons ish to 9 seconds, but stacked result looks ok. Above image is 4600sec ish, some subs will of been at start in daylight can cull those later when I do it with a bit more effort

quick preview stretch of m16. i think i got more detail/contrast around the pillars but over stretched it for this jpg. looks promising. no rgb stars taken though for testing.

I was just a bit shocked, flat wizard for broadband flats takes about .2sec lol

It's a great area for stuff.

Er clouds so doing flats Is 9 seconds unusually long?

I took a 10 minutes test on squid and saw no squid. So I went to the safer plan.

I'll upload a pic of mine when I get chance

for 2 mins, looks ok. guiding is a bit iffy hoping its how low it is in the sky. im zoomed in a bit in nina. also no clipped pixels dark or bright. which i think is ideal?

was just double checking ty

I'm on M16 right now. Had to polar align a little later and with 7 sec subs. But it was still daylight my first 2 mins sub looks good gonna look at stats 100 ish x 1 min which is pretty good i think the flag im shooting through/past is making my guiding a bit [removed word]. once i lose m16 for the night in about 30 mins ill try ngc6888 crescent nebula can compare it my broadband version... ....which is what a sensible person might say. I'm tempted to go squid hunting.

Really? I just assumed it was mass printed. Did it look better worse or?

Wow your faux filter response printout graph looks identical to mine That's some impressively consistent production svbony has well, printouts anyway

Basic "plan" is f2 mirror and three infinitely stiff tubes meeting at a point somewhere above/behind f2 focal plane. With enough space behind focal point and where the tubes meet to be able to fit a camera and focal reducer in a cradle and suitable adjustment in 6 (8?) axis... Just thinking of how to attach the mirror to a baseplate for the tubes is hard. I'm assuming rest is impossible otherwise someone would already have tried it. At some point I'll learn some basic cad to at least sketch it out.

Turns out clear outside was correct and I just got covers on before downpour

Everyone already is

I lolled Then I hastily scrolled up to the pic I posted earlier to check I hadn't done same

This image is amazing.

Yeah been testing that. How much I need time I need to grab RGB stars I'll find out. Starting at 30 minutes I think

Pretty certain this will be my first option, but no harm me having other options to compare results to hopefully my 1970s orange brown colour scheme will be a thing of the past

Sure but I have the other siril stacking option to stack into separate Ha and Oiii results. I literally have no idea the pros and cons of each, other than one is via a stacking script and other works on final stacked results. I'm sure I'll try both

Siril also does this, but on a stacked result only.

cheers for all that. all i've seen so far is in the siril guide and its not much, but im sure i'll find more if i need any after your tutorial i've already saved your tutorial to a text file for handy reference. im fairly sure this is a tool i that was only in pixinsight so im very happy to find siril has it

Er not seen the linear match tool. All I've done in my experiments with fake hoo was ha to red channel and Oiii in green and blue channels. Doesn't look great but then it wasn't real ha oiii. Need to look at linear match in siril. It sounds like what the normalisation feature in pixinsight does?

Apologies if this is repeat post, I thought I'd replied I'm going to stick with unity gain = 101 to start with, and will up my exposure times if needed. but with clouds and satellites and such, I think 5 and 10 minutes sub times are out, so might need to up gain if 3 min subs seem under exposed. does that seem like a decent plan?

yeah i ordered a spare one of those from svbony with my filter for my svbony filter drawer. looks very similar, but dunno if identical. i'd like a holder to hold one or maybe two of them
