Looks good, not an easy target.

I just took a look at the Flat you posted earlier and there is definitely vignetting, which means the flat does not work.  

Carole 

Might be worth checking the histogram of flats you have previously taken to see where the histogram is on those.

OK it is more faff to do it this way, but if the Flats Aid doesn;t work it is giving you even worse faff.

I have come across this problem before with two other new imagers using the APT flats aid and it to me doesn't appear to work properly.  APT is an excellent bit of software otherwise.

On both occasions I got the imagers to use the histogram and simply take a flat exposure without using the APT flats aid.  Make your length of sub short enough so that the histogram is about 1/3 to just under half way across.   

This has resolved the problem in both cases.

I must tell IVO (APT)  about this problem as he is very approachable.

OSB on the inside is all done. I put a trapline on the top because rain was forecast.

 

 

Good job too!

 

 

 

It's coming on well Graeme, I love the puddle of water in the tarpaulin.  Lol

Amazing images.  I only passed through Akureyri by way of flying there from Reyjavik en-route to Lake Myvatn in February some years ago.    

Iceland is such an interesting and different place to visit.

The bumps in the middle picture are mountains on the Moon. 

Isn't there enough junk up there already, but at least what is up there is for a purpose, but adding more just for entertainment.  Honestly!!!

Hayes is pretty close to Bromley, could be a good place to look. Beckenham too.

Nice area to live in but will be Bortle 7/8

It’s up to 778 now.  Share and share.  

Live away from New Cross.  I am in Bromley and it it still Bortle 8.  If you go as far as Sevenoaks area, especially place like Otford and Shoreham there are trains to New Cross from there, it will be much darker.

It’s odd that used CCDs can’t hold their price, it has been said many times that the advent of CMOS has not suddenly made CCDs incapable of producing a first class image.

Exactly, but everyone seems to want CMOS now.

The sale of second hand CCD cameras has also gone through the floor 😪

l was going to sell one of mine Atik428EX but seeing the low price someone else had to sell for thought l would rather keep it than give it away.  Might come in useful at some point. 
 

Carole

I think Atik have stopped making the CCD cameras.  But as you say keeping the specs on a separate page on Atik’s website would be helpful as people are still using them.   I certainly am. 

Not sure about the QSI cameras though.   I recall having a conversation about them at Astrofest but as l don’t have one l didn’t retain the info.  

Might we worth contacting them.

Well done Wesdon, I am glad our advice helped, and you'll go on to bigger and better things.  Guiding will make a heap of difference if you can get to that stage.  

As some-ne humerously said before some of us did far worse images when we started out, I'd be ashamed to show any of mine, or even if I still have them lol.

Carole 

That's come out really well Bob.  Yes keeping OK, a few old age "creaks" besides.  Hope you are OK too.  

Carole 

Not brilliant but how's this?

Yes, Elp’s description is more detailed and helpful than mine.  
I will have a go at it when l get on the PC, but l am sure you want to do it yourself  

Carole

I don’t use elements but if you have a layers option l would take a copy of adjacent brickwork that matches paste and slide until it matches other brickwork and covers the poster.  Flatten. You may need to do this in more than one iteration.

Excellent images and lucky you. 
 

Amazing image. 

Wow

It's by showing what you have done and getting advice from more experienced imagers that you learn.

I did a quick "fix" on your image above in Photoshop, using gradient exterminator:
