Im planning on getting one bay, or do I need it?

What an incredible image. You must be chuffed with that accolade 

Incredible Olly. Thanks for posting. 

Hi Daz.

I run a dual set up but have two cameras. Balancing is not at all difficult but may be a pain if you are constantly changing the camera between two scopes.  I guess if not imaging through both then it’s extra weight being carried for no benefit. 

Great shot Simmo, and agree when the other replies.  Colours and FOV excellent. 

I’m a paid user too. It’s fantastic and has great support.  

No response to my original question.  Try again!

Im at the planning stage of a 2.2m dome.

Concrete base - how many ducts need to run inside the concrete - is two enough?.  Does anyone have a false raised floor inside for cable management?  How do you get the cables from the floor to the pier base, if the pier base is separate - does anyone run the ducts through both? 

Pier - what’s the optimal height for the pier, if I’m currently using an EQ6, intending to likely change this in the future to a Mesu 200.

Im sure I’ll have more questions as I don’t want to mess this up!  I’ve built two ROR sheds so far but they are a bit more forgiving for retrofitting things and also more spacious.

Thanks for your patience!

Regards

Adam

Thanks all for your help above.  I think I'm beginning to get a grip of developing narrowband images.  Obviously still a lot to learn but I'm much happier with these first two attempts at HOO.  Now to think about what to do with the stars 🤔

 

 

Thanks

Robin, those look great. A major improvement

Lovely Iris, Adam!

I also went for this target recently, but I won't be able to process it soon. By that time, you might be able to shoot that RGB too.

If interested, when I get back from holidays, I can share with you some 11h of good full frame DSLR data shot through the Esprit 80 from under really good skies and some luminance too.

Gyulbudaghian's nebula looks interesting too these days, like a jet, and it's not too far out of your framing

Hi Alex, thanks for the comment.

So i google this nebula that you mention, and then realised that it's beside LBN 468.  Then I remembered I imaged it last year (cheers for that) but never got round to processing it properly.  So I restacked the data tonight and a quick run through PS, and I've very quickly attached the data to the mosaic and it actually joins up.  (This was before I paid attention to orientation of the camera on the scope).  Looks like an opportunity to do a larger mosaic.

"LBN 468 is a nebula 1,600 light years away from earth in the constellation Cepheus.  At the bottom right there is a nebula is called Gyulbudaghian’s Nebula. The reflection nebula is generated by shock waves from a contracting protostar, PV Cephei."

Thats a super rendition.....love that deep area full of faint fluff, 

Thanks Peter for your comment.

Whether we choose to 'nail' an image with a vast amount of data or move on must, surely, be a personal choice.  

Personally () I hope that Adam goes after the RGB for his luminance because the luminance is very good indeed. This is, of course, a difficult target but it is, therefore, an interesting one. It's also interesting because the small dusty structures are so utterly bizarre. My brain absolutely refuses not to see human figures. I also wonder if they might not be fractals - but I'm already out of my depth.

Thanks Olly, I too see people

I’d not heard of the “Ghost Nebula” until seeing images of it recently on SGL.  Is it the little bat-like thing at the top of your mosaic?

Good image by the way.  I never have much luck with the dusty stuff, I think my background light pollution is too much for it.

Thanks!  I think that's part of the 'Ghost Nebula'

Great result Adam.

Mick.

Cheers Mick, thanks

Fantastic job Neil.  It's pretty darn hard from the UK, but such a great target.  I can clearly see the POC in there

Looks like some sort of internal reflection. Do all the filters produce this with flats?

Light getting in around the camera or filter wheel?

NO, there is not, please read my last post... 😀

Read my last too. I acknowledged I was incorrect lol

@Peje I would take it off, recheck and then you can be sure to rule out that as an issue.

Thanks, I will look into getting a decent flat panel. 

I have shot flats on my iPad resting on the dew shield and currently am using a computer monitor. I’m not aware of any issues in my flats. They looks exactly like Ollys.

Is the iPad display definitely not changing when sitting on the dew shield? I needed to set up guided access to prevent the white display from changing when I used mine.

Also I had a ring like that on an image recently when I was shooting too early in the evening, too much like getting in and reflecting perhaps? Or getting in somewhere else.

That’s superb Alex.  This gives me that good feeling, knowing that winter is just round the corner. 

A beauty. Thanks for sharing.

Too late to go out and check but I am sure when I was making adjustments to the worm shaft I kept unscrewing the wrong cap as there was not a slotted nut on one side. It has been a while since I had to touch anything on the mount though.

That sounds about right! Sorry for questioning you on that.

I am sure there should only be one locking nut for the worm shaft.

I think there is one on each side of the worm gear.

Not sure if this is the right place to post this. I am really liking the sense of scale of the MW and realising just how small we are.

45s x 500 frames.  Captured and video processed using AllSkEye software. Thanks Mike, it’s totally fantastic and transformed my experience compared with  the supplied software @AngryDonkey

Can you fire up pics Pete. It’s be easier to compare with what should be there.

Sorry, and another weird thing. 

For the shaft bearings, theres only a lock ring on one side. I found that when tapping I had pushed the pulley side bearing out a bit and the pulley fouled the casing. It wasnt difficult to fix though, I found it strange there wasnt a lock ring on both sides

How is the other bearing held in place?

Just now, Peje said:

Didn't remove worm shaft as the pulley was really tight on it, I couldn't slide it off at all. I did a little tapping and got it to slide up a bit but it seemed like too much effort for no real gain and risk of breaking one of the bearings 

I still think it could that shaft/cog. I think I would have removed it since you went that far anyway. Those bearings are around £3 for SKF ones from a motor factors, and pretty much they won’t break unless you hammer the bearing itself. 

When I removed the black cap covering the end of the worm shaft I could see the centre of the shaft spinning for a second before the scope would start moving. I deduced from this that the cog was loose.  

Did you remove the worm shaft?

Sorry Adam....this comment was NOT aimed at you, it was just a general comment regarding the general quality of some images posted........

I didnt think it was, so no problems at all Dave.  I agree and I much prefer one good image, than a few ok ones, I think it's a virtue that comes with age lol

Thats is really stunning Mick, very unusual.
