Second imaging session in 2 days!?!

Wow, two great nights of stars! Completely new thing... haha
Well, I took full advantage of it once again, and started imaging the Orion Nebula in Narrowband.
Tonight, I did 2 hours (and a little extra for the core) in Ha.

I'll move on to the other filters the next time the sky is dark!

Last minute, unplanned session.

Hi everyone, its been a while!
The skies have, been absolutely pathetic for the last few months.
At times, its been that bad, I've almost given up at times with astrophotography!
Bad skies along with a few gear/setup issues, which have been a pain to sort out, due to lack of time in the garden all hit my confidence and enjoyment.

Anyway, last night the skies where clear... very good skies to be honest!
And at about 7pm, I thought 'sod it'.
I set everything up found a target and....
Issue.  The tracking issue I've had for a while.
Well, after about an hour, I discovered what was causing it (wrong tracking details in EQMOD and PHD2).

So, this left me just one hour... so while I had the Narrowband filters in, and Orion was staring down at me, I revisited the horsehead.

This was 12 x 5minute shots, binned 1x1 in just Ha.  Only 3 darks too!
So, yes... rushed big data and not much on the calibration side.
I just wanted shots! :)

Here's the result.

Another go at The Ring, M57

We've had some really nice dark skies this weekend and I've been busy...
Unfortunately busy in the none astro way.  So didn't manage to get out into the garden.

However, on Monday night, I decided to have a few cheeky hours chasing after the last failed target, M57 the Ring Nebula.

For this image, I took the below....
14 x Ha, OIII and SII  @170s each
14x Flats for each filter @30k ADU
10 x Darks (Used Ha Filter...)
236 x Bias (Ha filter again, @0.1 second each)
I never realised the Ring Nebula was so small... and cute. :)

Powered Focuser!!

One of the most annoying things I've found, when setting up the equipment it finding good focus.
This is mainly due to the fact my telescope is outside and my laptop is inside the shed. So I have to go in and out all the time to focus.

Well, not now.
I've bought a dc motor focus controller, made by Moonlite so I can manually control focus from inide the shed. 😍😁
It's not as good as say an ASCOM style focuser, which is users pc control and focuses automatically.... But these cost a LOT more money.
Roll on next dark skies, and hopefully faster focus.

Bloody Windows Updates!!!

The skies where almost perfect for me tonight, so by 8pm I was out there all setup and ready to go.
This was an improvement on last night, which was also lovely and dark, but my NEQ6 mount decided to throw a wobbler, so I had to rebuild it instead of taking photos.
Anyway, tonight, with a working mount I hit the skies!

All setup, all programmed to take 13 photos of each filter, for exposures of 180 seconds.
Target, M57 the ring nebula.

I hit start, and then thought... I'll go watch some TV with the wife while the magic happens.
WHAT A NOOBIE MISTAKE.
While I was inside, Microsoft forced a windows update onto my laptop... and forced a restart!!!

I managed to get some images, but due to restart, all tracking, all alignment and everything else gone.
So I ended up with basically bugger all again.
I managed maybe half an hour of HA data... so stacked that.
No bias, darks, flats... just the HA.
Tomorrow, I'll have a motorised focuser I need to fit to the Moonlite, and a shorter drawtube, which will fix some issues I've had too. So while I'm at it, I'll put the IDAS D2 LP filter in the filter wheel.

Anyway,  I digressed...
here's the HA data I got.  (Still in B/W)

M27 - The Dumbbell Nebula



Hi Everyone.
Last night, I finally managed to have a half decent imaging session!
So first light on the new camera, filters... and god knows what else that I've bought since last winter.

As it was my 1st shot, I wanted an easy target and one I thought I could process easy too.
So I chose the M27 Dumbbell.

Hope you like it, its EASILY my best photo yet. :)  (Scroll down for the one I took in 2017, and see the difference!)


Ha, OIII, SII - 170s x 10
Darks x 10
Bias x 236

Flats NONE   (I'll do these later and have another go at stacking!)

New Season, New Toys!

Well, its that time of year again when I can finally blow the dust of the telescope.

Its been a long long time since I last had a good session in the garden, and since the last evening with the stars I've treated myself to a LOT of new equipment!

Firstly, I upgraded the NEQ6 mount, to have the Rowan Belt mod.  This should now give less backlash and track the stars much smoother. (Unless I broke something during fitting! haha)

Secondly, the big upgrade. I've stepped up my camera from the Canon 1100d, to a new ZWO ASI1600MM-Pro!
This is an amazing camera, if you just google the name of the camera and see the results, you'll understand.
As I live in a reasonably light polluted area, I've gone for narrowband filters from Baader to get me going.  This should really really up my game.  Along with a 5 position filter wheel and new Baader coma corrector, I'm hoping for some amazing photos this season!

Hope to post some new photos soon!

Flame and Horse Head!

The best thing, about severe cold weather coming in... is the clear skies at night, before the snow hits!

So I jumped at the chance to get in the garden early, setup everything and shoot as soon as it was dark enough.
As per usual, issues happen.  When doing test shots, I noticed the collimation is STILL out. :(
I really need to figure out collimation, as according to my Cheshire, its all collimated ok.
Ahh well, thats for another night.

I finally started shooting at the Flame and Horsehead nebula around 7:30pm, which was around the time of full sunset and darkness anyway, so no loss.  I was aiming for around 30x 300s exposures to start with, then swap camera battery and try for another 1.5 hours after that.
Unfortunately, 40 minutes in when I wasnt near the Laptop, Microsoft thought it would be wonderful to install a new major Windows 10 update!
This force restarted the Laptop, and lost me all my tracking, and all settings I'd been using!
Damn you!
So, I only managed 40 mins of data.

I also used my DGM Optics NPB filter for the first time too. I believe that its aimed more for Visual work with Nebula but as the moon was out and bright, I gave it a go, seeing if it reduced moonlight and helped the Nebula's pop out. I think it did ok!!

So, today I thoughts I'd process the data I had and HOPE I managed to get some sort of image.
I'm pleasantly surprised with the result, I was expecting a lot worse!
I managed to take some much better flats this time, so the viginetting was almost gone, and I dragged the data out as much as I could so the Horse was visible.
I'm sure there are a million photos out there much better than this... but, Boo to them.
I took this one! :)

So... now the moon is becoming more of a pain, I'm going to find a star... and collimage the damn scope, properly!  (Or try)

Finally, a Dark Sky!

 January, was a pathetic month for dark skies.  The weather was simply aweful all month.
I think I managed two nights out, in total!  And one was a full moon, so managed no Deep Sky Photos!

Anyway, its now halfway through February and I finally had a dark sky, bonus points, no Moon either!!

So I spend about 4 hours out in the garden, shooting a new target.
I choose the M33 galaxy, Triangulum.

Not the easiest of targets, especially with a DSLR and not being in a 'Dark Sky Area'
But I gave it a go.

Two hours of data, 24 5 minute frames. All of them turned out perfect too!  Bonus.

I then spent a few days processing the data, and discovered that the Flat files I took, must have been bad. As there is a shocking imbalance I noticed during processing. :(

So, I had to crop... burn... and butcher the image best I could to produce an image I can be at least a little happy with.

Here is the results!

M31 - Andromeda!  Our Galactic neighbour.

Hi everyone, I've been back in the garden again, trying to get some good shots and generally practising with the camera and ISO settings.
I have also been practising taking flats, with my LED light screen, and believe I have mastered them!

Below, is now my favourite photo I have taken and processed to far!  Hope you like it too!
