![]() They hold collimation very well, and are generally considered to be bullet proof. If you are just starting out, a refractor is a good way to go. SVX, Espirit, and TS Photoline are the ones I've been eyeballing. I'm right there with you, a 120-130mm frac is in my future. Right off the bat the frac was competing with my newt in terms of image quality (after drizzle). I started out with a Newt, and now I have a 70mm widefield frac as well. Theres so many people in this hobby that love their Celestron gear, but I'll never touch it. Sorry for changing the subject but if anyone wants to suggest a refractor around 1000mm FL I am all ears!įracs are the way to go. My AM5 mount can handle the Askar with a 11 lb counterweight but no more than that. ![]() ![]() ![]() I can spend up to $5000 or $6000 for a refractor and am thinking of the Askar 130 PHQ or the Explore Scientific 127. The thing about refractors that I love is that the stars are sharp and pinpoint-assuming the optical quality and mechanical quality are up to par. Computer processing is a totally different story-I find it very enjoyable and challenging and always eager to learn more. I am like a guy who loves to drive a nice car but has no interest in getting under the hood and messing with stuff. I honestly don't want to collimate or dealing with mirror shift- I want to spend my time imaging when I am outside, not tinkering with the optics. The whole process from setup to post processing is very enjoyable for me. When I bought the Esprit 100 last fall, I immediately started getting high quality images. I am seriously thinking of selling the Edge and getting a 130-152mm refractor. The Photoline f/7 apochromat is fully suitable for astrophotography, however, like with any fast refractor, the field has to be corrected so that the stars at the image edge stay nicely round.Thanks all for your comments. CNC tube rings and GP style dovetail bar included.Internal baffles and very good internal blackening for contrasty images.M63x1 thread (female) for threaded adaptions and 2" / 1.25" for pushed adaptions.Overdesigned draw tube for full illumination even with full-frame format.The support is decoupled from the adjustment of the draw tube. Ball bearing supported focuser with rack & pinion adjustment.102mm f/7 FPL53/lanthanum glass lens for an image free of chromatic aberration.Thereby the performance of the lens can be fully implemented photographically or visually. The new PhotoLine 102 mm apo offers, besides a lens of the latest generation, also a mechanical equipment which leaves nothing to be desired. Very fine mechanics guarantees joy with the telescope and universal application capabilities. This means that the fast refractor is not only very well suited for astrophotography and wide-field observation, but also for moon and planets. Even at highest magnification, the image remains free from distracting chromatic aberration. By combining FPL53 (Ohara, Japan) and a lanthanum element, a chromatic correction is achieved which matches the one of an FPL53 triplet - with significantly shorter cooling times. This apochromat from the PhotoLine series from Teleskop Service offers very good performance in any application area.
