Astro Photos
 
Not ideal viewing conditions due to some low cloud which wasn't supposed to be there. But, as I had stayed up late I was determined to get something. The weather forecasts in this country are never correct, and I mean never.

Anyway here is a shot of our nearest neighbour in space taken with my EM5mk2 but attached to a low cost Startravel 80 scope. Focussing is manual and this pic is set of 20 shots stacked. What strikes me is how bright the moon is and the detail you can see visually even through this low quality scope.

Not as good as some others on here but at least its mine.

A better one from last night.
Used EM5mk2 with Nikon 80-400 + TC14II ( 1120 mm equivalent).
Glass makes a difference

Very good. Must take some more myself as its a few years since I pointed my 75-300mm at the moon.

Nicely done
Seen any noctilucent clouds while waiting up?

Certainly have seen Noctilucent clouds in my late night observing.
That is exactly what created the challenge

Plenty of detail in these. Given the exposure times you must have been using I interested to know what advantages stacking gave you? Bet the DSLR lens was easier to focus. If this was on your mount had you thought of using the high res mode of the em5 mkII?

Stacking gives you more detail especially if the visibility is not perfect due to heat haze or thin cloud cover. Ideally you need a minimum of 12 shots for it to work best but the more the better. i have seen some images with more than a hundred shots stacked.

Manually focussing the scope is a real challenge but at least with live view and magnification up to 14x its possible. Using a DSLR lens is certainly easier but I only have the Oly 12-40 which isn't any use for the moon. So I attach my Nikon 80-400 lens via an adapter so thats manual as well.

I would love to try Hi-Res mode on my mount, but I think it only works with the Pro Oly lenses. I have seen your hi res moon shot and wanted to see if I could get close to the detail you achieved but yours is still better.

I am deliberating whether to get the Oly 300 + TC or to get a quality refractor telescope. Its about the same cost.

I know this dilemma I opted for the 300mm and no TC mainly because I could use the lens for other normal light photography. The real problem and total frustration with astrophotography is getting good dark skies and there are so few of them where I live as you know only too well.

Reprocessed Andromeda with a trial version of Pixinsight.

That, to my amateur eyes, is a stunner Dave.

I am making the most of a 45 day fully functional free trial of pixinsight. Its pretty amazing software, been watching YouTube tutorials in the rain today and thought I would have another go with my Andromeda shots taken earlier in the month. It is really targeted at processing deep sky images.

I'll echo what John said stunning. I really must have a go soon.

Had another go last night. Managed to get 3 x 5min tracked (but unguided) shots using my EM5mk2 with my Nikon zoom attached at 400mm. The longer exposure time really makes a difference on the detail in the outer arms of the galaxy. Would have got more but I knocked the camera and lost alignment. Also managed to time it so I got two passing satellites !

Really struggling to get auto guiding to work but will get there one day.

Only seeing the second shot above it is super.
