I reside in the central great plains of the United States, and recently our west coast has been set on fire by rioters and arsonists due to civil unrest.
The smoke from these residential homes and forests burning, is delivered high into the atmosphere where it hit the jetstream and has traveled well over 1000 miles to blanket my sky.
While i can still take some images, it has greatly reduced my session quality at 393nm. Naturally the smoke properties absorbes or reflects much of this wavelength. The sun is very white in the sky in fact, white as a cotton ball in some areas.
However, i am vigilant in my attempt to capture something out of the new active region. Please be patient while this data is processed.
First we have a look here at the paris meudon bass2000 spectroheliograph , which records its daily calcium k3 core full disc. I have added an arrow to the tiny area that my scope is focused on at about 2400mm..
Full image disc citing goes to paris meudon observatory, with corresponding link to the wonderful and most vital French institution. http://bass2000.obspm.fr/home.php
Next from my telescope, operting with an explore scientific Firstlight 127mm x 1200mm achromat. In the focuser is a Skybender tilt module with some calcium filters supplied by Apollo Lasky. I am using a Meade 2x telenegative barlow in the eyepiece of the skybender, and a basler aca1920-155um cmos camera for recording.
Look at those calcium ribbon's! This is a rare capture, seldom seen since cycle 24, a decade ago.
Have decided to sell my trusty Equinox ED80 refractor. Sharp optics, smooth two-speed Crayford rotatable focuser, fitted with a finder shoe, and complete with the original Skywatcher case and tripod-threaded mounting bracket. A 3D-printed Bahtinov mask is included, along with a pair of mounting rings and a Losmandy dovetail plate.
Collection preferred (Sussex coast, not far from Brighton), payment by bank transfer or cash on collection.
Looking for £325.00
With my eye on an Equinox 120 ED, I am wondering if it's focuser can take an Astro Physics diagonal + ES 40mm Maxview total close to 2kg if not more - sort of challenge for any focuser bar imaging kit.
The Featherlite is almost half the price of scope again!
If any of you are interested in a star party in East Suffolk, we have been hosting a Star Party every March and October at Hinton, near Saxmundham, Suffolk at a newly developed Caravan and campsite, Haw Wood Farm, for the last 5 years. It is £12 per pitch per night with electricity hook up (adapter needed) call Dan or Georgina (see link below). Some of you here may know about it; on good nights we have had a SQM reading of 21.75 - it can get dark enough to see the Zodiacal Light! Many local society members meet up: Norwich, Castle Point, North Essex, OASI (Orwell), DASH (local) and Breckland among others and it is generally friendly and welcoming (if we can see you in the dark!). Saturday 14th we run an event: a skytour or talks in the cafe, dependent on weather. Unfortunately, timing clashes with the SGL star party but we're a long way from it.
