  1. Great first night out! always exciting to hear about first light especially with a large dob which just sucks in photons like a black hole 😂. Regarding detail on planets especially Jupiter, it is good to have a look 

    at your collimation and see how close to perfect you can get it. Jupiter has so much low contrast detail it tests telescopes limits. 

    Clear Skies and enjoy!

    This was my surprise tonight with my dual RASA8 rig. No idea how it got in and no idea how to get it out. I guess I just have to live with him/her until he/she dies and falls of the corrector plate and hopefully ends up in a corner and not on the main mirror. Any complaints on my star shapes I will direct to this insect of the family Chrysopidae. Yes, I am an entomologist too so it may be a insect revenge......

    There must be an opening somewhere but given the commitment it took to get in, it deserves to be there 😂

    I actually don't mind it at all :D

    I'll probably be covert agent of Bortle regime that infiltrated rebellion?

    Not covert at all as you’ve just revealed yourself! Now I see why you wear a mask in your avatar.

  4. It seems there are others who feel the same as I when it comes to bortle. A rebellion against the bortle scale is on the horizon and I shall gladly lead us to freedom!! face paint and all.

    I introduce the Milky Way visibility scale. Now I have to figure out the levels of visibility and how to determine them.

  5. In my early years as an amateur the word "bottle" didn't come across my radar, this is back in the mid 90's. When describing the quality of skies we used magnitude, I recall reading an article in an astro magazine describing

    the beautiful sixth magnitude skies of Arizona. Forward a decade as I dropped out of astronomy when I got married and had to get a real job and a home, suddenly I encountered the word bortle!. Right away I knew I hated it, I can barely 

    say it, it sounds awful, not sure how one can hate a word but I do.

     

    When did "bortle" happen?

    I have a bad dose of Takitis and my dream scope would be a Takahashi TOA-150. However I would swap it for consistent dark skies with stable seeing. Indeed I would swap it for 1 good clear sky a week, local street lights malfunctioning and a constellation of telegraph wires disappearing in a bunch of sparks :)

    You make a great point, a dream scope is worthless under garbage skies.

    Maks and SCT have corrector plates on the front so you can’t use a simple fan. You can use a specialist cooler  that is inserted into the scope through the focuser and circulates air through the scope and blows it back out.

    I’ve had both maks and SCTs but have now moved on to a Classical Cassegrain which is open at the front so cools down faster and no dewing problems. Also uses a proper crayford focuser and fixed primary instead of the mak and SCTs moving mirror tpye focuser.

    Have to say that is a beautiful looking setup.

    Interesting. Do their internal design make a cooling fan difficult or impossible to incorporate?

    Honestly, I have never heard of a cooling system for a mak, maybe there are some models I am not aware of that are cooled. Don’t let my experience stop you, as mentioned there are many here on SGL who love their maks and have gotten around their weaknesses with inexpensive and nifty solutions. Maybe have a search in Mak related threads here on SGL, you’ll have a better understanding of what they offer vs what you want. Would I buy another Mak? YES! now that I am aware of some tricks others have used to make the experience easier I would gladly have another, one look at Jupiter through a Mak and you’d be sold.

  9. Rest assured that "dream scopes" and I just quoted myself 😂 are most certainly not restricted to bank busting triplets and gargantuan dobsonians. Having said that, I can speak of Mak's as I have owned one in the past few years and loved the planetary and lunar views they produce. One drawback which was a dealbreaker for me was their long cool down time and relatively narrow field of view comparing to a refractor. Unfortunately I do not have time to let a scope cool for an hour or longer, this combined with my yearning to have a quality refractor led to my selling my mak, I do miss it, though. There are some who wrap their Mak's in insulative material which they say helps greatly with the cooling issue, if you love planetary and lunar combined with great portability then a Mak may be the scope for you. There are many tips and tricks on Mak's here on SGL for Mak owners, they are planetary/lunar killers.
