This is a crop from the full frame of SH2-132, the Lion Nebula.
80 mins Ha
145 mins O3
200 mins S2

I combined these as a blend. Mostly HOO but with S2 added in all channels. It is a weak target, so I am pretty happy with this.

I will also have a play with a more conventional SHO mix to see what it comes out like.

I agree it's extremely impressive, but rather than be jealous I prefer looking on the bright side. Not only time to make a mug of coffee but prepare dinner as well. :)

For our server we use Hetzner, from memory they also offer online multi terrabyte storage solutions. when needed its what we will do to supplement our server storage for Roboscopes

I may however not suit what you need :)

didnt know blackblaze backup . Unlimited for $7 / month ????   where is the trick !


it is a simpler ‘barebones’ service and lacks some of the functionality of other services. Functionality I have decided I don’t need.

main problem is that it only covers one PC, and does not include networked drives - so I guess storage capacity is limited in the typical PC. They have a more ‘professional’ offer for business use which is more expensive. I haven’t had to use that yet.

I also belong to a generation for whom "if the data is not stored in three separate places, it does not exist!".

I use BackBlaze for cloud backup as it offers unlimited storage for a fixed monthly fee. I have checked the ability to restore specific directories (always a worry) and it works.

My Desktop is fairly old and the motherboard does not support M2, otherwise, I would be doing the same.

On my NAS I only use disk-mirroring or simple disks, having had one NAS die on me and being unable to recover the data from the disks that were still working.

1Gb fibre? I am jealous!

I use Acronis backup - with premium membership you get 5TB of storage.  It take a while on normal download/upload speeds but once the new fibre to the house link is working I will have 1gb in each direction...

I agree with you - spoken by someone who knows!   I am a n ex CIO - you know what they say about CIOs - a little knowledge in dangerous  :-)

I do use my NAS for backup but I also do a cloud backup too - great point about off site disks too - my wife has a hard drive backup in her office!  

All the best

Hello
off topics discussion about storage 

in my point of IT ingeneer , you have to split  your storage in 2 
one fast SSD harddisk  , or even better an M2 disk for preprocessing of the data , it make a huge difference when reading writing the data. 

large disks for raw data and processed data , can be on a NAS if you want , but NAS are not really made for extensive wrting, especially public NAS 


Also , you have to think about backup , never buy a disk alone, always 2 , one for live operation , one for backup (offsite backup if you can do it ) . 
i prefer small disk ,  i never go over 4To disk for live operation  , a disk failure on a 18To disk , you lost sooooo much data ... 

NAS are not made for backup but to share data across network . If your synology raid card is faulty you lost everything ! 
always backup your data 
mine are :
-in my computer (10years old, still ok to process data !)
-in a huge WD 12TO external drive nin my house , synchronise every day, 
-Synchronise in a distant NAS at a familly house , synchronise once or two per month
-very cold backup on spare HDD , drop in my office, synchronise two time / years

I m obbsesed with data loss :)  



Cheers

Indeed - I went through that a few years ago.  For 2 or 3 years now we have had fibre to the cab then copper as usual to the house with BT.  My biggest complaint about BT is that they award the highest priority to the person who phoned last.  We get good speed for a while (60mb minimum supposedly) but then the contention builds up on the BT network.  the ned County Broadband network doesn't touch BT as far as I understand so won't have the same limiting choke points - we hope!

That's a serious set-up Mark. I particularly like the SSD's. I had been thinking about adding one for Pixinsight swap files.

Transferring around my LAN I am limited by the Synology NAS - it's a consumer version and not all that fast.

I have had FTTP for a couple of years. I ended up going for the 80Mb/s offer, because I have found many of the sites I use can't deliver at a really high speed. What I do get with this subscription is guaranteed service and low contention ratios, so I rarely have any practical problems. I may go higher at some point, but for the moment we are all revelling in the improvement over the previous 2Mb/s (max!) ADSL connection.

To be honest Mark, I can only think of one reason i'd need internet that fast coupled with alot of storage haha

jokes aside, I wish I had internet that quick :) I'd have my server just downloading completely 'legal' full movies all day long haha

I wonder if Roboscopes could get a bulk deal on storage solutions ;-)

Disk space and performance are key aren't they.  I run a 20TB NAS with 4 spinning drives (an older Synology 416Play) for my storage, but have 4 x 1TB SSD drives in my PC arranged in a single stripe to give the best possible process for my now aging (4 years old) gaming PC which I bought for astro processing.  I also have a bonded pair of 1GB network connections to the NAS with a wired 1GB network round the house and to my observatory at the bottom of the garden.  On Monday, County Broadband are hooking me up to their new fibre to the house installation on the village - then I'll have a 1GB connection to the internet.  Yippee!  But will that turn into a purely local win as I find out that the services I use cannot supply a fast enough link over the web.....  time will tell!  I'll have a warm feeling either way ;-)
