North America and Pelican in Ha

First Image in more than three years…. just a screen grab as it’s not good enough for a full size jpeg.

A quick process to re-learn what we’ve forgotten in that time!

7x 600seconds taken at 385mm f/3.6. Dark and flat frames applied.

Calibrated and stacked in Nebulosity. Processed in Photoshop CC 2017.

Been out a few more times since then to try and sort out issues with guiding, mount control and the Robofocuser having stopped working – we’re slowly getting there!

Think now I have a total of 17 subs on this to sort. Then I’ll process again with a bit more care and attention to the finer details and stars. That should (hopefully) be the Ha sorted.

Next year we’ll try and get the SII and OIII to make up a false colour image.

Lightning!

Just had a hefty thunder storm over the hills from Westendorf, Austria.

I quickly downloaded the iLightningCam app that Ed mentioned (well the free version to trial)!

This was the result from having a play with the settings sitting on the balcony from our room (hand held no less)…

Noctilucent clouds over Streethay

Yes, the same ones Andy has also posted!

Woke up, looked out the bedroom (back) window… could see them bright as anything. Shot round to the front and grabbed camera. Couldn’t get the angle from my office window. Tried Julie’s office window (also on the front), but no joy… Headed downstairs in dressing gown and into back garden. Pulled wheelie bin out (for small tripod) but still no joy! Opened side gate and plonked tripod on car roof and started taking pictures…. rang Andy’s mobile – no joy, rang house number…. got a pretty vacant “…..heeellloooo…”. I think my curt response went something like…” Andy, it’s me, you need to get your arse outside, Noctilucent clouds..!”

This is a 1 second exposure @ f/2.8. ISO 200, 48mm focal length was shot at 3.30am on Friday morning 6th July 2018

My trusty old full frame Nikon D3 on a small travel tripod, itself sitting on my car roof.

Off the iPhone6…

Noctilucent Clouds from Steethay!

Sunday 24th June.

Observed around 11.10pm looking North (out of my front office window) – North North West (so just to the right (East) of the earlier solar pillar.

jpegs straight from camera, no processing. Taken between 11.20 – 11.40pm

Really tricky to stop the street light flare hitting the lens…

Nikon D3 (full frame) and Nikon 24-70mm f/2.8 lens.

All ISO 200, f/2.8, 70mm focal length and between 2-3 second exposures.

Towards the end of this run I could not see the NCL’s as they had grown too faint.

For orientation: the same picture above, but with annotations

Solar Observing and Evening Treats!

Sunday 24th June, a chance to get out and do some solar observing – can’t leave it all to Nick and Roger after all !

I double checked my usual sites to see what was happening on the sun, they suggested enough to warrant pulling all the gear out.

Invited the big ‘A’ to join me, he duly did after 2.15 as we set up the gear.

Forecast on ‘Clear Outside’ app was correct, indicating 90+% high cloud cover…

This did have a detrimental effect on the observing to some degree, especially in my longer focal length scope, but you have to take the opportunities when they present themselves!

We both took the chance to do some sketching and it was good to see that Andy’s Calcium Quark actually worked – an “enhance white light” view, being my description.

We were more than pleased with our day as Andy packed up after 5, me not long after…

But the day wasn’t finished…

Looked out my North facing front office window to be greeted with a Solar Pillar – about 9.30pm.

Took a quick snap with the iPhone, then rang Andy. He seemed a bit perplexed at first for my call and a ‘Light Pillar’, but I urged him to go outside, then put the phone down pretty abruptly and went to grab a ‘proper’ camera.

iPhone image 9.34pm:

And again at 10.07pm

Even later into the evening, I spotted roughly in the same position what I thought could be noctilucent clouds… never seen them before.

Having left my tripod at work, I quickly grabbed the GorillaPod and took a 3 sec exposure – ‘NCL’ confirmed !

Texted Andy… no reply…

Those images will appear in a new thread!

Solargraph in operation…

Got a few Solargraphs loaded last light (Wednesday 20th June), just in time for today’s Summer Solstice.

Attached mine to it’s usual place on the back of the house (facing SSE), before heading off for an evening walk with two under my arm to deliver to Andy (he beat me to the blog entry – see below)!

Andy has one of the new style cans to try – donated by Ed who has a fine taste of coffee (Azeri / Lavazza – I also like this version). I did make the extra effort to drill a bigger hole in the can, then fix tin foil over it and then pin a fine hole through that. The only ‘issue’ with these cans is that I only get three sheets out of a big sheet of B&W photographic paper, whereas I get 6 when cutting for a standard baked bean can.

Good job as well that it was set up ready for this morning – today was pretty good and should have set a fine ‘upper limit’ on the paper for when we open the  can up and take a look after December 21st…

This morning, in action (around 8.15am) !

Crescent Moon 17th June 2018 @ 10.46pm

Thought this made a pretty picture – moon between branches of the front trees (slightly cloudy as well giving plenty of ‘glow’!)

Taken with my spare works camera, a Nikon D7000 (16.2 Mp on a cropped sensor), with my glass on the front:

Nikon 1.4x teleconverter and Nikon 70-200mm VRII f/2.8

Settings:

ISO 160, 1/30 sec, f/4, Focal length 280mm (420mm in 35mm full frame terms), hand-held.

RAW file processed twice in Adobe Lightroom for the background and then the lunar features. Composited in Adobe Photoshop CC 2017.
