Mosaics during a full moon

A full moon is too much even for my narrow band filters!

In my limited mosaic processing experience, the more gradient that you have, the more difficult to get clean seams.  I would personally not attempt any further mosaics unless the targets are high in the sky and with little or no moon.  I do think that the Photometric Mosaic script does a much better job with the joins than Gradient Merge Mosaic, but even then, when I've tried this with any significant moon or towards areas of the sky with more LP gradients, I have struggled to get it to look acceptable.

Get a longer scope, and you can mosaic the moon itself.  Forget about deep sky.

I have a 81mm frac and a 20omm Newt, but the full Moon just doesn't appeal. a couple of days either side, and yeah, that's a good idea!

with the 533MC it is a no go. If you had a mono camera you could do ha or sii if you are reasonably far away from the moon

Well I shot the Cygnus loop so let's see how that turns out. The trouble is, it's SO cloudy here normally I want to try and use any clear night.

Woah!!! That's amazing. 

I've totally discounted mono imaging as I genuinely live in one of the cloudiest places on earth and I just wouldn't get enough time to collect enough data, but that is staggering. 

I was pleased enough with my shot, but it doesn't really compare! I've only had a veruy quick play with it so will settle down one night and try to learn some new techniques. 

Oh! So have I got the dual narrowband with my NBZ filter, but could add an Sii filter to get different data?

Sure you can. Technically there is nothing holding you back to do that.

However, something very interesting is happening, at least Askar has started selling a Dual Narrowband Filter that covers both Oiii and Sii.

The big plus point of using such a filter instead of a pure Sii filter is that you get your Sii Data „for free“ when shooting Oiii data and when the moon is not too bad you also get free  Oiii data when shooting Sii.
And Sii data is often the weakest so wasting a lot of integration time on it without any other benefit can be frustrating.

I have the Askar filter on order and as soon as it arrives and I have clear skies I will test it, they claim it is halo free but my trust in marketing Blabla for Astro Hardware is very limited.

There is also a friendly Youtuber from Switzerland that has the filter on order so expect also some coverage on Youtubefor that filter. (View into Space) 

I also just watched a fresh video from DSO Imager where he talks about differences between Mono and OSC, he is a little biased towards Mono but he presents all the hard facts in a good and easy to understand  way. Definitely worth the watch, much better than a lot of other videos on the topic.
