Hi, i..m on Stargazers Lounge for long time ago, but now i have a new scope at last!!! The scope is a Skywatcher classic200p dobsonian, and i received it just one month ago. I.m really happy with it. For now, i.m using the stock eyepieces that come with the scope, a 25mm and 10mm super plossl 52. Yesterday i was received a Celestron Omni barlow, and that expands my magnification range. I posted some pics with my set.
Congratulations to Stargazers lounge team, this is one of the best sites to learn about astronomy and equipment.
Besf regards to everybody
A DSO image in planetary settings.
This is the Eskimo planetary nebula. Small as they are, this one has less than 1arcmin.
The image was taken with a C11 f10 and ASi224. No cut-off filter was used.
The capture was made with Firecapture and 2s exposures. The final processing was in PI.
My first attempt at M57. I attempted to capture the extended halo by gathering some OIII and Ha data and then blending these into Blue and Red channels, respectively of an LRGB image. The image below represents about 21 hours and was taken with my Esprit 150.
LIGHTS: L:13, R:13,G:8. B: 10 x 600s; Ha:13, OIII:14 x 1800s. DARKS:30, BIAS:100, FLATS:40 all at -20C.

Having seen another forum member's deep sky experiment with the ASI120MC camera, I tried the experiment myself.
Here are e1e2 Lyrae, the Cat's Eye planetary nebula, NGC6210 and NGC6572 all imaged with a C8 SE and the ASI120MC. The planetary inages are single image captures, while the double-double is processed from a short video stream.
I also tried M57, and while I could see it in purplish colour at an exposure of 8 secs, I could not get the Sharpcap live stacking to work.
From an EAA point of view, this camera and planetaries are a definite hit, as the camera and laptop show them better than the eyepiece, and in colour.

Tonight was the best night out in a long time. The last couple of days the sky has been crystal clear, and today is friday, which meant nothing was on the schedule for tomorrow.
Scope, filters and eyepieces:
Today, I was using my one and only Skywatcher 10" dob, with my collection of explorer scientific 82 degree eyepieces. For the first time in a long time, I also used my CLS filter.
Before I headed out, I decided to have a look at skysafari 5 to see what I should have a look at this clear evening.
Tonights list ended up including:
M13 looked fabulous as always, but I can't quite bag the propeller. I was resolving stars nicely, even a couple in the center, when using averted vision. I think M13 looks the best at 136x and sometimes at 255x, however most of the times I think the image is too dark when observing at 255x.
M92 was a surprise. Locating it was surprisingly easy, as I through the finderscope could just see it as a little faint dot. Looking at it through the scope was amazing. It was not as big as M13, but at 136x it looked very nice, and sometimes, it almost looked like the stars formed a smiley:-) Surprisingly I was also able to resolve a good amount of stars in this cluster, but not as many as in M13.
Now I know this wasn't on the list but I thought I had to give it a go when I saw it on skysafari. NGC6229! Also located in Hercules, and via starhopping also easy to find. This was the smallest one of them all, but the most rewarding since this was my first object from the New General Catalogue (NGC). I was also using 136x at this target, because this is the most comfortable magnification in my opinion. I was only resolving one or two stars in this target, but it was easily visable, just as a bright smudge.
M57 is by far my favorite object (out of the few objects I have seen). The contrast and shape of it gives me the WOW feeling everytime I observe it. Now this target I was observing comfortably at 255x and it looked amazing! Now this was where it popped in the CLS filter which almost made it look like the red outer-part of the nebula was visable, but this faded soon after. While observing this target for about 20min I was thinking if a UHC or a OIII would give me better or the same views?
M27 was kind of disappointing, but I just think I have overestimated how it would look like, but it was still a very nice view it gave me at 136x and 85x. The dumbbell shape became more visable over time, but I think the thing I like more about M57 compared to M27 is the contrast between sky and nebula.
In the end it was one of my best nights I have had with my new (5 months old) scope. I have yet to try it at my grandma and grandpas' where the milky way is visable, and I am very excited to do just that.
