here is an image of Mars I took yesterday. I haven't managed a decent pic using phone afocally so I decided to try something different.
Scope OMC250
Eyepiece Pentax 14mm XW. and x2 barlow giving x300 Mag.
An old Win7 laptop and SPC880 upgraded to 900nc.
set at 640x480. 30fps in sharpcap. messed around with gain to see what would happen.
Used quick capture.
Stacked in Autostakkert and a bit of wavelet in registax and a final tweak in GIMP2.
The data was collected by holding the webcam up to the eyepiece and standing very still
I can see the colour is a bit off but overall I am happy with a 1st go.
Any feedback appreciated.
Cheers

Hi David
I have 3 culprits in mind .Martian dust, Atmospheric moisture or the bright Moon.
I just don't know which one it is

Hi Mark,
Never under-estimate the power of the ortho
I think it's low number of elements mean you lose less light as it travels through the optical train. Not as issue usually but on something right at the margins it can make all the difference.
I keep meaning to have a go at this SN but I forget whilst trying to tease out details in Mars.

Hi David
Very good sketch It looks very similar to what I could see around 8.30 last night.
The details were quite low contrast last night, although there part of the I think it was Aeria appeared quite orange.

Hi Mark
Very nice pics.
I put mostvof the mushiness last night down to lack of scope cool down time, But the seeing might have been deteriorating as well.
You got some nice detail in there
cheers

I decided to have a go at sketching Mars last night.
Gut back from work about 10.30pm and the ckouds were clearing.
The scope did not really have enough time to cool down but there wasn't much I could do about that.
The first sketch is the pencil drawing the second on I have added some colour.
I might have another go if we have a clear spell next week.
Scope OMC250
Eyepiece 6mm ortho.
Magnification x375
Seeing 3/5
Transparency 3/5
Time 22.55-23.15 UT 23/10

Hi Steve
Very good pic.
It reminds me of the detail I could see on the 15th.

Hi mark
Very good sketch
The seeing was a bit variable last night but there were periods where it was excellent.
What amazed me last night was when the seeing improved the edges of the features were very obvious.

Very good sketches Glob
Some good detail in them.
I had some excellent views of Mars last night.
I had spent some time on collimation and it paid off.😀
Keep the sketches coming.

Excellent result, well done

I would recommend "observer's guide to stellar evolution" by Mike Inglis.
Published by Springer.
It combines the theory of stellar evolution with actual examples we can observe.

I have answered yes as my skies at home are ok but if I can go somewhere with darker skies I will.

Hi, Welcome to SGL.
I'm just up the road from you
Doubles are good targets when you have significant LP.
Enjoy the scope

Good catch Jeremy 👍 I had a fairly good view of the conjunction using my 15x70's. I decided to keep the scopes tucked away given the breeze ☺️

It was a fairly easy spot in my 15x70's last night just to the left of Venus. It was nice the clouds got out of the way for once 😊

Hi Stu, great pics. seeing was pretty good last night.
Thanks for highlighting the crater names. I am still learning them
Cheers

Nice pics
I had a look at this last night through my 15x70 Binos.

I have done this in the past.
Mostly Afocal . The advantage of doing it this way is the ability to vary the magnification. I think the closet pair I did were around 2-3".
Most of my images I posted in the double star section of the forum.
I plan to start again soon.
Cheers

Interesting idea. I know from experience increasing magnification allows you to spot fainter objects. When I observe double stars mag 11+ stars which are not visible at x70 magnification start to appear once you get into the x100-150 range.
I guess the only way to find out is to test an ethos against an orthoscopic eyepiece :).

Tim, excellent image,
I was looking at Betelgeuse yesterday and it's dimness is very noticeable. It seemed no brighter then Bellatrix.

Well done, conditions were not easy

Very good pics.
The second pic certainly captures how it looked to me. A tiny dot and alot of fast moving clouds

Hi Pete
Same here, first contact was clouded out but I did get to see about 30-40 mins of the transit
Great pic.

Hi Dave
I don't have the nosepiece. I could only use webcam as it came.
I think it was having a go and hoping for the best.
Cheers
