Thanks Carole, looks like I'm just over the water from you so similar conditions, appreciate your input 👍

I think I'm going to get the Oiii and Sii, now just deciding between sticking with ZWO to match the Ha I already have or a set of Baader narrow band and selling the ZWO lot.

Thanks Carole, sounds logical, which do you use for focusing ? I've been using the Lum as it lets more light in.

Hi all, should have really researched before I bought the 5 position wheel 🙂 I ventured into mono a short while back (ZWO 1600mm / 5 pos wheel / LRGBHA)

I've been so impressed with Ha at my LP garden (RED/WHITE ZONE) that I'm now thinking I should have got the 8 position wheel !

Whats the best shortcut to try ?

take out the Green filter  - put in an Oiii, therefore still allowing RGB with a synthetic green,  try Ha - Oiii of some sort or go the whole hog and ditch the RGB and get Oiii and Sii ... leaving an empty slot ?

The 8 position would be too much additional expense so that route is out of the question and probably too big / heavy for the Az-Gti anyway

Opinions gratefully received

It's a long thread, but mostly positive 🙂 mono version of your cam, but same results

Does look a bit excessive but I guess it depends on processing ? What does a single sub look like ?

There is a very long / informative thread about this on cloudy nights , might be worth a read.

Good news is that the camera can create excellent images as the glow normally calibrates out .

Possibly, there are 2 apps, the pro version allows EQ or Alt Az ... Both are free though.

(EQ mode needs a mount firmware update and is only worth trying if you have a wedge and want to try long exposure imaging)

Should add , I'm using Android

Reset alignment gives it a 'fresh' start ... I never bother though.

In 2 star align, you choose 2 stars then begin alignment, th mount slews to first star ... Approximately, then you manually center star with keypad, then again on 2nd star.

Also, in settings - connection you can choose emulator so you can play with the app without connecting the mount. Just remember to change it back afterwards or you'll be in a dark field one night trying to connect and after 20 minutes you'll remember !

I really like that, I'm so tempted to get an O3 and S2 filter to go with my Ha.

Really beautiful !

Thanks Alan, just down a bit from Cassiopeia .

Sounds like a follow up book to 'Turn left at Orion' 😄

Thanks for the comments guys, do you think the noise is due to the amount I had to stretch the image, the fact it's only 70 minutes or that it was on a full moon night /  red lp zone ?

Ha is the best decision I've ever made in astro imaging !

I live in a red zone, nearly white ... took the plunge and went mono cooled recently. Obviously could do with more data as it's heavily stretched as was near  pretty full Moon but I'm amazed how this turned out seeing as the sky was bluey orange.

Thanks for looking

Long shot but have you tried different usb port ? Also disconnect any other usb devices while you are aligning maybe.

I love NB imaging! some people don't like the imaginary colors but I just love'em! 😍

How do you keep the star colours natural looking ?

Thats beautiful, makes me want to invest in an O3 and S2 filter !

thread needs some humour ... you've got the lens cap on the polemaster !

seriously though, hope you get it sorted soon.

Gutted for you Ahmed, I know nowt about Ioptron but unless your polemaster is moving on the mount it shouldn't jump like that ! 

Looks beautiful Gary ! There's something special about a truss design, maybe it's the ability to see the innards and suss how the light path works. Hope you get to use it soon ! Tonight looks promising 🤞

Nice job.

Another happy paid user here. Well worth the money and as said by Alan, Ivo is very helpful.

No, but not a bad idea for a little earner 🙂

Dylan O'Donnel uses the RASA and I think a ZWO1600, very similar ... might be worth a look.

Cheers Peter, yep looking forward to Mars as I've never managed any detail at all so far.

Very nice Brian

As a rough idea, see if you can see the ir on front of your TV remote with a phone camera.
