Nice to be imaging again.:)

Haven't imaged since early December.

This is nebula ( IC 447 ) is quite unusual, seems quite a different blue to other similar nebula, even in a single sub without processing.

I need another 2 hours on this but it looks promising.

Thanks to Ross G for recommending it.:thumbsup:

That's a really nice object and a great image, Justin. I don't remember seeing it before.

Cheers,
Rick.

nice work Justin, how long were your subs?
definitely a much deeper blue indeed, very interesting.
how's the cooler box go in the heat? i'm contemplating a cold finger mod ... we'll see.

clear skies!

Hi, Justin, very beautiful. Sharp too. The scattering of warmer stars nicely complements the reflection nebulosity. Cheers, Mike

I've taken the bait Justin :-)


Yes mate, go for it. It looks like an interesting bit of sky that will make another great addition to your portfolio, and I look forward to seeing the finished product.

Thanks Rick!

lovely image.:)



Thanks Rusty!

Sorry about that, subs were 2 minutes.
Seems perfect for ISO 6400 under dark skies .

The cooler box is struggling, only 10c below ambient. I need to replace the internal fan, they seem to wear out frequently which mucks up the cooling.
It should be running 15 to 17c below ambient.



Thanks Mike!

I find balancing the stars to nebula tricky, makes quite a difference when the balance is right.:)



Thanks Trev!

Glad you nibbled.:D

Hope to get out tonight if the cloud clears.
I must update my photobucket site, I'm a bit slack in that area.:rolleyes:

Cheers,

Justin.

Thanks Simon!

Are you going to try it with your setup??

I'd love to see what it can do.

Cheers,

Very nice Justin. There's a lot HA signal around this object and make a contrast with the blue of reflection. The unmodified camera doesn't help about.

All the best,
Leo

Thanks Leo!

I noticed the HA regions in Ross G's image, must be reasonably faint not a lot showing.

Cheers,

That's really cool Justin, I'll have to track it down and try out my new camera on it.

Thanks Jo!

What camera have you bought??
Look forward to images from it.

Cheers,

I bought a Sony A5100, I have a few projects lined up that need a small light camera with low noise and this suited the best. I tried it out on the scope on Friday night and it's looking like it should work great. The 24MP should really help out with my wide fields too.
I also got a Samyang 12 f2 lens for it and it is amazing for nightscapes.

Cheers

Hi,

managed to get some more data, not a lot only 40 minutes.
It has made a difference, colour coming through better and a little HA too.

Hope to get more data Monday.

Cheers,

Justin.

hi justin sorry to hear about the fan, are you running a computer fan? i have switched to RCCI over MPCC just now (which gives space for nb and other things), first test on spacing (only two subs before clouds rolled in) i think i have it about right- those varilocks do move slightly when you are tightening other parts to them hmmm. because i'm going OAG i think a cooled finger may be my go (noise was un fixable with the sensor at 33degs and now i have some more space).

i think the 40 mins extra has really upped the image too :thumbsup:

cheers

Thanks Rusty!

It's similar to a computer fan, blade configuration is different and mounting. Having said that I am using a mother board fan at the moment.

A cold finger is the go, saves on weight. I'm too chicken now to mod my camera's after stuffing up one my 1100D's.

Cheers,

Justin.

Hi Justin.

Great looking photo. Nice colour and very sharp.

I love the closeup composition you are getting with the 8".

For the exposure time, you have captured a lot of detail. I had to push mine to 11 hours to get anything decent showing.

Continue adding exposure and you will have a standout image of this beautiful object.

Good luck.

Ross.

Thanks Ross!

Hope to get close to your image, definitely needs more data to bring out a smoother image with vivid colour.

Cheers,
