Had three sessions last night, the first the CPRE Orion star count with my 11 year old daughter, magic.
The second was from the light-blighted garden mid evening - successfully picked up M41, M35 and M67 all for the first time - then a neighbour put on more lights so had a go at Polaris, nearly, almost sort of resolved as a double this time.
After a tea and warm break I managed to convince myself that the Mak 127 carry over to the park at 11:30 pm constituted allowable lockdown exercise (body AND mind officer...) so headed out to a wider and, it turned out, reasonably darker viewing spot in the park.
I haven't yet much comparative experience of conditions but I would say seeing was quite steady while transparency a bit milky. Winchester sits in a river valley and I suspect this may be a local feature until I can get up & out of town. Anyhoo, what started as proof-of-concept of some grab & go bag & padding ideas, turned into a really super session of clusters and doubles, most of which I had never seen before, & fruitless searches for fainter things.
Technique-wise I brightest star aligned on Sirius and Arcturus & did have a few accuracy niggles with the GoTo , however a combination of the Telrad + 10x50 Bino sweeps got most of the bright targets quickly in the Finderscope and centred. Highlight has to be the Beehive, M44 which I found breathtaking & can't believe I have never looked for before, Beta Mono triple-star which was amazingly 3D and set me off on a Tatooine sunset imagination-trip and M67, dim & red the kind of place where Klingons might hang out! After much reading on here over all these starless nights I had made a list and although I deviated a bit from it and failed to find ANY galaxies or planetary nebula, the list was a great idea and reminded me that I wanted to go and hunt down the targets in Cancer which I would otherwise have forgotten and missed two of the highlights of the evening. Eventually my phone battery gave out and as I was wi-fi tethered to the AZ GTi this ended my session shortly before frost-bite ensued.
That dew shield was a good buy
For what its worth, here are my notes, all observations made on SW Mak 127 on AZ GTi, Baader Hyeprion 24mm 68 degree fixed for most & occasional higher mag on Baader Hyperion 8-24mm Zoom. Telrad & SW 9x50 finder, supplemented by Celestron Nature DX ED 10x50 Bins.
Had a great view of Mars last night at ~11.30pm. Best I've seen it so far this year I think. Sketch below.
I think the darker regions in the S are Mare Cimmerium, Mare Sirenum and Mare Chromium.
Could also clearly see the South Polar Cap and limb cloud at the following side of the planet.
Messier 57 is is just coming into a position for a decent look around 11 30 pm. IT is a colourful object and I thought it would give me a good target with which to practice my colour developing in PS/Lightroom. I have read so much about how to produce a LRGB image from the four stacked/calibrated luminance, red, blue and green images, a lot seems contradicatory and some, when followed, gave me colour yes, but not as we know it. I am sure a fair chunk must be put down to me. Anyway, I now have a work flow which gives me colour, sometimes resembling what other people have obtained. Progess of sorts.
This images is based on 114s subs at gain 139, offset 21.

Messier 57 Ring Nebula in Lyra
NASA: M57, or the Ring Nebula, is a planetary nebula, the glowing remains of a sun-like star. The tiny white dot in the centre of the nebula is the star’s hot core, called a white dwarf. M57 is about 2,000 light-years away in the constellation Lyra, and is best observed during August. Discovered by the French astronomer Antoine Darquier de Pellepoix in 1779, the Ring Nebula has an apparent magnitude of 8.8 and can be spotted with moderately sized telescopes.
Equipment: Celestron 9.25 XLT at F10, Skywatcher EQ6 Pro GEM, ZWO 1600MM Pro, ZWO EFW with ZWO LRGB filters, QHY5IIC guide camera on Skywatcher 9 x 50 finderscope, Celestron Focus Motor
Software: Ascom 6, Eqmod, Cartes du Ciel, AstroPhotography Tool, PHD2
I'm from Hungary. This is my first post. I am glad to be here.
Recently I'm trying to sketch some deep-sky objects. I've made this observation yesterday. Cygnus was near to the zenith and the sky was pretty dark.
NGC 7000 is one of my favourite target. I like to observe it with any telescopes, especially with RFTs and with UHC filter.
Please excuse my language errors.

Spent just under 45 minutes at the eyepiece, so ran up against the issue of field rotation (really for first time in my limited sketching experience) and realized the importance of not only anchoring features to certain areas within the eyepiece, but also (and probably more importantly) using the relative locations between 3 and 4 stars at a time to make as accurate a sketch as possible.
