Greetings everyone, I am a student with a recent strong interest in astrophotography. I currently use a Nikon D3300 and I plan to get for my graduation a small refractor and a tracker mount, most likely a star adventurer. My question is, which is the best/most stuitable apochromatic refractor to use with the SA? The budget would be around 1000€ for all the setup. Thank you in advance and clear skies!!

My Dad has asked me to sell this lovely Tal 100R on his behalf, I hope this is not against the forum rules. I owned this scope before him, and the condition is as it was when I had it. There are a few chips in the paint and some very small marks on the objective. There is a scratch on the inner surface of the dew shield which creates a horrible reflection on the objective, however this is not visible when observing. It comes with the original diagonal, mount, tripod and box, but no eyepieces. I do have some Tal plossls of a later vintage that could be added to make a complete package if desired. I fitted the SkyWatcher spreader plate/accessory tray as it was much better than the original, but does take away from its originality.
I'm asking £200 and collection will have to be from Watford as it is a heavy item. The link at the bottom is to my first and second light reports of this scope. It sounds a little negative but that's only because the RS is that little bit better.
If you have any questions or need additional photos, just ask.
I purchased a standard GSO 6" RC telescope late 2016. As with other RC scopes, I've had my share of problems with the collimation. As many of you know collimation of the RC is a bit of a struggle. After reading much of the material online, it seems that the procedure boils down to multiple iterations with the simple Cheshire and something called as Hall of Mirrors aka multiple reflection effect. Below are the test images from tonight. Reference star is Canopus. All images are inside of focus, unless mentioned. The small rectangle shows the location of the star in the FoV. I also built myself an artificial star from Aluminum foil and LED torch and checked the collimation indoors. The indoor test is quite better as seeing conditions have not affected the judgement. As you may all notice, I've used Mire De Collimation exe file for final checking. I've not used a laser collimator or Howie, just a simple Cheshire and a real star, though I'd love to try again with a Howie Glatter.
I am looking for casual observation a Sky-Watcher Startravel 150mm Refractor OTA or similar 150mm / 6" F5 OTA must have tube rings & dovetale.
I have, if you are interested in a trade a Meade 6" LXD75 F8 Refractor OTA with finder & tube rings.
I can collect if reasonably local to Lowestoft.
Hello! i am being offered this 100ED at a price which is hard to resist by an acquaintance who inherited it and doesn't plan on "checking out galaxies" as he put it LOL, it looks like a well built scope and a good frac is a scope for life, anyone have/had this scope?
