18" and 20" someone told me to "STAY AWAY" from them, he heard a lot of bad reviews, mirrors are not good, he will not say that if he didn't hear or read, so it will translate that "bigger" in this case[Skywatcher] isn't "better".

I don't know where you're coming from Tareq, people often upsize to Dobs
of 18,20,22, or larger. There are no amateur level SCTs larger than 16" on
the market anyway, so if you want larger it has to be a Newt[Dob or GEM
mounted.]
I'd love to know who told you to stay away from the 18 and 20 SWs.
Everything I've heard says their mirrors are very good indeed.
You obviously didn't read the advert in the classifieds, the seller says that he needs money to rebuild his car engine.

Ok, good you told me about it, so if that someone will tell me to stay away from it then i will ask his proof, i am open to all suggestions or recommendations, i was thinking more about imaging, but i should really add visual in my experience, and all said there is nothing like a Dob for visual, so let's be it.

Thanks everyone. I got a dob. Last night was the first night. I was stunned with Orion Nebula which appeared to have a lot of light blue colour. I think I sensed traces of red colour on its edges but not sure if it was real.

Hi Den,

Seeing red and blue is REAL

You are fortunate to be able to see red in particular!

Read post No. 2:

http://www.iceinspace.com.au/forum/s...d.php?t=169840

Will serve you well to go through the whole article. Will explain a lot about what you see, what you don't, and why

Congrats on the new dob too!

Alex.

Your biggest challenge Den is knowing if you'll likely want to take long exposure pics any time soon. If so, then you will need an equatorial mount and should get either an 8" or 10" on HEQ5Pro, as others have suggested. Small refractors are where most people taking pics start out, but a newt, that is able to reach backfocus for a DSLR or other camera, is a great option for both visual and AP.

The AP bugs frequently bites unexpectedly and you may want to look over the should of those with PCs in the field taking pics next time you are able to visit a night gathering.

If you're fortunate enough to have time travelled forward 2 years and know for sure you will only be doing visual , then definitely focus on a dob on an alt/az "canon" mount. Then the challenges are whether to get active tracking, what eyepieces to buy, where you will keep the scope at home and how easily can you get it outside.

Thanks Rob, never say no but for now astrophotography is not of interest to me. The various pictures of nebulae and galaxies are awesome but one can easily find them online. Visual observation is the experience I am after.
Photography is a hobby of mine since my dad and I had a lab and printed film shots ourselves. I still prefer film black and white photography especially night city landscapes. There i have no boundary to the personal touch. Every shot is how I see an object. I do not see how I can have a personal touch with astrophotography. Maybe I am just new...

Re eyepieces, I have read some threads and it seems that for DSO’s I need 31mm, 17mm and 8mm. I got 17mm with extender to 14mm and stock 25mm and 10mm. Thinking about used Nagler 31 and Delos 8. Any suggestions are welcome

Cheers
Den
