Simon modified a cheap, old and unused telescope with significant chromatic aberration into a super high resolution Solar telescope, his video below explains how he did it.

Spectacular Early Morning NLC – 6th July 2022

Well what a sight! Four planets, the ISS and Noctilucent Cloud that just kept giving.......

At 2.32am an alert went out to members via WhatsApp from member Sonia who had spotted the NLC developing in the North East.

Several members picked up the alert and so too got to witness & photograph a fantastic NLC spectacle which lasted a long time into dawn.  The last photograph taken was at 4.05am!  The planets Venus, Mars, Jupiter & Saturn (which was in the South) where photographed with the NLC too. Then starting at 3.08am there was a bright ISS pass overhead.

Spaceweather.com wrote ''This morning, sky watchers in Europe woke up to some of the brightest noctilucent clouds (NLCs) in years. The clouds were amazingly bright and remained very evident deep into dawn.  The clouds didn't stop there. They spread south across Europe, backlighting the Eiffel Tower and completely filling skies in places where, normally, NLCs are confined to a thin band near the horizon.''

Below are a selection of stunning photos taken by members , Honor Wheeler, Jim Burchell, Diane Clarke, John Howarth and Sonia - all from North West Kent.

 

Four images of the NLC on the 6th July 2022 taken by Honor Wheeler.

 

Three images of the NLC on the 6th July 2022 taken by Jim Burchell.

Three images of the NLC on the 6th July 2022 taken by Diane Clarke.

Diane said 'Again following  a message from fellow member Sonia, I set up my equipment and watched in fervent hope that the NLC would develop, as there is always the possibility that they will dissipate shortly after becoming visible.

Like the other members of the society who were watching I was not to be disappointed as the NLC went on to develop into a fantastic display that really started to develop around 02.40 until 04.00 when it started to fade into the east as dawn approached.

The 1st image is a panorama created from 6 frames as the entire NLC was spread out over a large portion of the N-NE sky, that a panoramic view was the only option to encompass the majestic splendour on display.

This panoramic view includes the asterism known as the “Plough” or “Saucepan” within the constellation of Ursa Major, as well as the double stars Capella in Auriga & Mirfak in Perseus,  it should  be noted that the "Plough" contains 3 double stars including Mizar (Alcor), a rising Venus is also visible lower right above the tree line.'

Faint NLC – 8th July 2022

Well they just keep coming - more NLC albeit very faint spotted at 3am on the 8th July 2022 by member Honor Wheeler who sent the alert out to members.  As the NLC were faint to the naked eye members were willing them to get bigger and brighter but alas just a small patch is all that developed that morning.

Below are a selection of photos taken by members who responded to the alert.  All photos taken from North West Kent.

NLC at 3.30am.  A white whispy patch of NLC can just be seen in the centre of the photo. They are 7 O'Clock from the star Capella which is in the photo. Photo taken using an iPhone by member Sonia.

 

Noctilucent Cloud (NLC) – 5th July 2022

On the 5th July 2022 Noctilucent Cloud were spotted again.  They lasted from 2.25am until 3.40am and were in the NE to NNE direction.

 

Diane Clarke said 'Fellow member Sonia sent an alert at 02.25 to say that NLC were visible, so having pre-packed my camera & lens, I was off to take some pictures.  87 frames later I finally decided to get a little more sleep as dawn was approaching.' 
 
Below are 2 panoramic images of the NLC taken by Diane using a Canon EOS M50m2, Canon 100mm macro lens at f2.8 1/8 sec @ISO400.

Jubilee Moon – 2nd June 2022

Several members took the opportunity to photograph the waxing crescent Moon on the evening of 2nd June 2022 - The Queen's Platinum Jubilee Day and some stunning shots were acquired.

Making a Solar Filter for my Skywatcher 190MN

NEVER LOOK AT THE SUN DIRECTLY. Please click here for solar observing safely.

My Skywatcher 190MN telescope has a very wide field of view I can easily fit the full Moon or Sun on the chip, so I thought I'd get myself some Baader solar Safety Film and make myself a solar filter - the video below shows how i made it and shows some early results. Check-out our solar section for more images.

Mesu e200 Mount Unboxing and Assembly

[et_pb_section fb_built="1" theme_builder_area="post_content" _builder_version="4.17.4" _module_preset="default"][et_pb_row _builder_version="4.17.4" _module_preset="default" theme_builder_area="post_content"][et_pb_column _builder_version="4.17.4" _module_preset="default" type="4_4" theme_builder_area="post_content"][et_pb_text _builder_version="4.17.4" _module_preset="default" theme_builder_area="post_content" hover_enabled="0" sticky_enabled="0"]

I recently bought a Mesu e200 (also know as the Mesu MKII) mount. This mount uses friction rather than gears so doesn't have any backlash, it is incredibly accurate and can handle a load of 100Kg (that's 18 stone! or over 200lb!)

Check-out the video for the full unboxing and assembly - the video isn't a review but you will get an idea of the quality from this video. Whilst the mount is expensive, it is far more economical than equivalent mounts, other owners have sold their Paramount's  in order to fund buying more of these - they really are good.
