Moon 23/06/22 Daylight with IR Pass.

I wanted to see what could be done in bright daylight ~ 11:15am Thursday, with the filter.

Added Images, deleted mosaic.

They have turned out really well for daytime images.

I tried this a couple of years ago using a H-alpha filter and the end result was almost like a night time shot. But not quite. Your images have inspired me to give it another try..

Well done.

Thanks Roy,
As you will have guessed the sky was not that black before "adjusting" it, but was a whole lot better than no filter, this was the ZWO 1.25″ IR 850nm Pass Filter, I really do think it cuts down on the turbulence, and if I had got on with setting up and caught it at transit time rather than well past and over a house it could have been a lot better. 

There was too much gradient in the sky to make a mosaic, I did try but gave up with it. The scope was by now in direct sunlight and getting hot!

It would be interesting to see an H-alpha for comparison.

Venus next 🤔

I will try and locate my Ha image and post it here for you to look at. 

Let us know how you get on with Venus !

As promised here is a lunar image taken during the afternoon in April 2020 - i.e. broad daylight - with a Ha filter

Telescope - 16" F/4.5 Reflector

Camera - Nikon D810a

Exposure 1/1000 sec at ISO 200

Filter - Ha   (Lumicon 12nm bp I think)

Lots of messing around in Photoshop !

It was only a test shot and I only took two images to see if it would work.

Using a large scope with plenty of light gathering helped.

I now feel inspired to experiment further !

Nice detail! perfect sky, is that because your in Ha? Well worth more goes!

Must take a look at Ha filters, but it's going to hurt more than my £24 IR pass I suspect.

Thanks for uploading that.

[Roy Foreman]

Yes the Ha certainly does block most of the blue sky.  A #25 red filter works really well too, and is a much cheaper option than more specialised filters. Lets more light through as well !

I have just ordered an Astronomik ProPlanet 642 which has a 200nm bandpass and lets through Ha plus some IR, so I am hoping it will be useful for both lunar and deep sky imaging.

I was really inspired by the Hubble image of the Horsehead in IR, but I doubt my efforts will even scratch the surface, but it will be fun trying, if a little ambitious !!!

Lots of scope for experimenting, just need darker nights and more settled weather.

Nice detail , but the Moon set against a beautiful blue sky is one of life's little joys in my world ...

Agreed. Might try a colour version one day and see how that turns out !

I just had a read about this at FLO, it's in my basket now.
Interesting comment comment about improving guiding as well.

"installing the 642BP in front of your guiding camera dramatically improves guiding quality, as image-motion from one frame to the next is minimised."

[Roy Foreman]

Yes, from the description its seems like a very useful filter with multiple applications. Not sure about the improved guiding bit. I think the gains would be minimal at best.

So, all we need now is clear, but not necessarily dark, skies to try out these new filters !
