The Moon imaged through cloud from London on the 17th January 2021.
Celestron Edge HD11 scope & Canon EOS 6D camera.
This image represents first light with my new Celestron C11 SCT.
Conditions were poor with a gusty wind and cloudy periods but I was glad to get out with my new scope.
I needed to adjust the collimation but I am pretty happy with this as a first image. Hopefully lots more to come as I get used to the new setup.
Quite a bit of Martian cloud visible on the right (following limb) with a fainter patch over the Sinus Sabaeus towards the left limb.
Imaged with a Celestron C11 SCT and a ZWO290MM camera/Baader RGB filters.

My mount was polar aligned with SharpCap (what an amazing system for aligning). I'm not comfortable using my SCT as my lens yet. My solution is to piggyback my Sony a7RIII and adapted Canon FD 300mm f/4 L on a ADM dovetail rail on the top of my optical tube. I used DeepSkyStacker to combine all frames and then processed the TIFF file in Photoshop using my skill set and relying on the famous Astronomy Tools Action Set.

Thanks to my friend for help in getting this beauty to look right. I'm so excited about this image and the extra galaxies that filled the view and the beautiful skies that I was fortunate enough to see in Arizona.
After awful weather here for ages we have had a few clear nights. These have allowed me to capture a few images of Mars as it heads towards opposition on 13th October. The planet will actually be at its closest on the 6th October.
The evening of the 23rd September presented the best seeing conditions so far for me in this current apparition,
The planet was imaged with a Celestron C8 and a ZWO290MM camera via Baader RGB filters.
The North Polar Hood (bluish colour clouds) is showing nicely towards the bottom (north pole) and bluish haze is also evident on the morning - following limb on the right. The planet is rotating from right to left as viewed.
The iconic "V" shaped Syrtis Major Planum is departing towards the P preceeding limb. Above it is the bright Hellas Chaos.
The (shrinking) South Polar cap is prominent.

This is the second version of processing the stack of 43 photos and calibration frames (the first version is available under the link www.flickr.com/photos/bogky/29536110817/in/dateposted-pub...).
About this version:
I'm just starting to learn DSS for comets, so the first processing was unsuccessful: DSS "ate" the comet and I took it from single frames separately, today I aignmented a comet on all 43 frames of the stack and learned how to use the necessary DSS options and also took as a basis another frame (another time and position of the comet) - the comet is getting better in color (accumulation of a signal on the stack?). I found this version better ;-)
Sorry, but detailed description is in Russian only
Rus.: Комета Джакобини-Циннера в созвездии Возничего
Это моё второе свидание с кометой. На этот раз встречал гостью на своём балконе.
Конечно, городское небо с его интенсивной засветкой не оставило шансов рассмотреть комету.
Поймал комету не визуально, а с помощью функции Precision goto монтировки с автонаведением.
Координат кометы монтировка, конечно, не знала, но я их взял по планетарию Stellarium на ожидаемое время:
04.09.2018 1:55
Прямое восхождение/Склонение (на дату): 5h18m5.53s/+44°12'34.4"
RA=05h18m05.5s
Часовой угол/Склонение: 18h22m3.73s/+44°13'28.2" (видимые)
Dec=+44°13'28.2"
Далее внёс координаты в монтировку и она вычислила, что ближайшим ярким ориентиром станет звезда Капелла.
Показала Капеллу, по этой яркой звезде я скорректировал прицел и фокус, а уж потом монтировка автоматически перенесла меня к неведимке-комете.
И хоть визуально комету отличить не удалось, зато на фото (начиная с выдержки 10s) она сразу бросилась в глаза, отличаясь от всех окружающих звёзд.
Увы, цвет её богатого пышного "платья" с огромным шлейфом различить не удалось даже на фото (если искусственно усилить, то он бирюзовый).
За городом в предыдущую встречу различить цвет было легче. А городское небо обесцвечивает неяркие объекты.
Яркость кометы по данным планетария составила уже 7.12m, но на городском небе она казалась темнее.
Например, расположенная в кадре звезда HIP 24775 (SAO 40219, HD 34300) имеет яркость лишь 8.5m, а выглядит ярче кометы - на фото оказалась самым ярким ориентиром.
О комете см. ru.wikipedia.org/wiki/21P/%d0%94%d0%b6%d0%b0%d0%ba%d0%be%...

Это вторая версия проявки стека 43 фотографий и калибровочных кадров (1-я версия доступна по ссылке www.flickr.com/photos/bogky/29536110817/in/dateposted-pub...)
Об этой версии:
Я только начинаю изучать DSS для комет, поэтому первая обработка не увенчалась успехом: DSS "съел" комету, и я взял её из кадров стека отдельно, сегодня я обозначил комету на всех 43 кадрах стека и научился использовать необходимые параметры DSS, а также взял за основу другой кадр (другое время и положение кометы) - теперь комета выглядит лучше в цвете (накопление сигнала в стеке?). Я нашел эту версию лучше ;-)
Celestron CGEM2 EQ mount with the Nikon D810A, 135mm Sigma Art, Orion 50mm guidescope, ZWO guide camera. Home made mount plate for camera and scope allows me to adjust the balance left to right and front to back, as well as setup two cameras.
The 93Km wide crater Copernicus is one of the most famous features on the moon. The 2min. HD video capture by my Huawei P9 phone was converted to 2900 individual frames. They were stacked and only the 175 best was merged to a single picture.

The Lagoon Nebula is 8 in Charles Messier's "not a comet" list, 25 in the Sharpless catalog and 6523 in the New General Calalog.(NGC) It is a cloud of ionized hydrogen estimated to be 4000-6000 light years from earth. It can be seen with the naked eye as a gray/green patch in the constellation of Sagittarius..Almost in the center of the photo can be seen NGC 6530, an open cluster of young stars formed from material within the nebula. The entire nebula is roughly 110 x 50 light-years wide.

A blazing almost 75% illuminated moon was too hard to ignore in the still air of Christmas Eve. Thin cloud beginning to increase affecting the seeing a bit but still had to image...
