  1. I was at my skintest when I first got into astronomy 20 odd years ago. Oh well nothing's changed there then😉

    Seriously though, the choice and price range of equipment available now has never been better (supply issues notwithstanding).

    It's the same in most hobbies, the point at which you're past the 'entry level' is in my opinion solely down to the person doing that hobby. To some, my gear is still entry level. 

    I do agree that recent price increases won't have helped things, but buying second hand is always a good option.

  2. First light for the Skymax 90, BCO 18mm and RGO 7mm.

    I had the Skymax mounted on a new-to-me Altair Astro Mini AZ mount, on my First Horizon tripod. I had already balanced it and let the scope cool down outside for a while. 

    Found the Moon easily even without having the finder aligned, although I did align it while I was there. Using the TV Plossl 25mm first, nice and sharp as expected, but I could see the seeing was a little off. Perhaps this explains the tiny yellow fringe on the lunar limb. I don’t recall seeing it when using the Tal 100.

    18mm BCO. I have very rarely ever bought an eyepiece brand new, but I did get this one new, from Harrisons Telescopes. Like the TV plossl, this ortho is very sharp, and comfortable to use. The full disc of the moon still fits within the field of view. Excellent detail along the terminator. No yellow fringe, or any other false colour.

    10mm BCO. Again, a very sharp eyepiece, but this one was second hand and could do with a clean. Still comfortable to use, but tonights’ seeing limited its use.

    7mm RGO. The seeing didn’t allow this eyepiece to really shine. I have had one before so I know how good it can be. Still reasonably comfortable for me.

    Altair Mini AZ. Very simple to use, needs good balancing to work effectively, but once balanced is very easy to track the target even at high mags. Surprisingly stable, there were slight gusts of wind this evening, hardly noticed them at the eyepiece.

    At about 18:10, I noticed a star close to the limb that looked like it was going to be occulted. I have never actually seen an occultation before so decided to wait for it. It was slow going, and I kept checking the time to make sure I had it exactly. At the critical moment I glanced at my phone, and when I got back to the eyepiece, it had disappeared! Ah well, at least I had the time down - 18:38:48. I checked Stellarium for the star, it was 99 Tauri.

    After that minor disappointment, I packed up, satisfied with the rest of the session and very happy with my super lightweight setup.

    First image is through the Televue plossl, the second through the BCO 18mm.

  3. I need something that can do everything my Tal RS can, but in a much smaller package. 

    So, here is my new to me Skymax 90 mounted on my Vixen Polaris, easily carried in one hand. Doesn't even need the counterweight.

    My first ever Skywatcher telescope, I'm impressed, it's very well made and considering it's the older version, it's in great condition too.

    Hello! I am a space enthusiast, who has a very simple 70mm f/10 refractor with a alt-az mount. I believe I have seen everything what this scope can see neatly. It can't show me much in the light polluted skies of my cities. I am looking for a cheap telescope upgrade around 160$, which will be my second and more serious telescope, I will like a dobsonian or a eq telescope. Suggestions? Also it needs to have free international shipping, because I live in India.

    (P.S. Sorry for my bad English, I am not perfect in this language!)

    With your budget, finding something that represents a step up will be difficult, but not impossible.

    I don't know how easily available astro equipment is in India, but I would look out for a second hand TAL 1. It's a pretty good Russian reflector, on a reasonable EQ mount. They are easily available here in the UK for well under £100. I got one for free - £0!

    If you decide to go this route try to find one with the later 1.25" focuser so that you can use modern eyepieces, otherwise you'll be limited to what they come with originally. They're not bad at all, but are a different size.

    The downside is that the setup is heavy, so I doubt anyone would post from abroad.

    It's a Takahashi illuminator, and it looks very much like a Takahashi finder as far as the focusing eyepiece goes. However I've never seen a Tak finder with the adjustable/focusing front cell, so perhaps it's a hybrid, though it could be a true Tak. The crosshairs on the Tak finder are very fine and engraved onto glass, so that would indicate if its a true Tak. Also, Tak finder tubes are smooth with no groove for a rubber O ring.The finder bracket is not Takahashi!

    The Japanese script on the illuminator says Takahashi.
