Hi, I got a skywatcher skyliner 200p dobisonian a few days ago, my first observing session was out in the cold and the telescope dewed up when I bought it back in. I then noticed that the glass on the base of the telescope(not the primary mirror inside) was smudged and had a little ring shaped scratch on it. I tried cleaning with a lense cloth but it is still slightly dcratched and smudged. Does anyone know if this makes a difference to the inside primary mirror?
having started with a 130P on an eq mount.I wanted something with more light gathering on a alt-azimuth mount. I didn't want to go down the Dob route although that would have been a lot easier and cheaper.🙄
So I have now got a 200P on a Skytee on a Manfrotto tripod.
My question is why do all the pictures I have seen of this set up have the scope side mount rather than the top mount.
Is it just a question of weight if you also add counterweights under the top mount? I understand the recommended max weight is 10kg per mount although some places say 15kg.
As it is a lot easier to mount the scope on the top mount than the side one (I nearly dropped it on the first attempt) and it seems counterintuitive to have the weight of the scope hanging off the side mount instead of sitting on top of the top one.
Hi! I'm Fran
Not so long ago I took a picture of the ISS I never thought I was going to be able to get with the equipment I have.
After saving for a long time, I was able to buy my first scope, an OTA Skywatcher 200P. I adapted it to be used in a dobsonian base because it was the cheapest way I had to get it to work.
One night, I thought it might be cool to try to aim and record with my phone an ISS pass overhead. During the first attempt, I messed up the focus extremely bad but you can't imagine how happy I was to get a white blob in a frame that only I knew was the ISS.
The following afternoon I tried again. This time the flyby was almost exactly overhead and the night was crystal clear. So I manually tracked the station looking through the finder scope and recording it with my phone at 1080p 60fps. Without much expectations I downloaded the files into my computer to review them. And was shocked with the results.
The video was processed with PIPP, AutoStakkert and RegiStax.
If someone told me the image was taken with a phone and manually tracked with a shitty dobsonian base I would not believe him! I got really lucky that night, but I can not be happier with the results. I believe I got to the edge of what I can accomplish with the equipment that I was able to buy. I'm not sure if ext step up should be a real camera or a mount. Anyway, any of them are too expensive 😬
If you want to see the frames before processing (and some nice shots of the moon that night), I'll leave a link to the video where I show them:
Thank you so much for reading it all.
I've been dabbling for about a year and am having a lot of fun.
Nothing too serious and I don't have mega expectations but I'm starting to wonder if my images could be sharper and there's something I'm missing.
I'm attaching a picture which is the best 10% of a 3 minute video with 500d 'bolted' straight to the 200p f5 scope. No filters...no barlows...just camera straight on.
It's sharpened and saturated after the fact so in every way this is the sharpest I can get it.
I've always had the same issue whether it's with a single shot, stacks of shots, or stacked video.
Views through the eyepieces (circle-T 12.5/25) are mega sharp!
I'm happy that collimation is very good and it was a remarkably clear night tonight.
All in all I'd be pretty happy with this image (maybe over exposed a bit...) if the craters with shadows didn't make me want to rub my eyes.
Thanks in advance for any thoughts or advice!
