First kit and I feel like I'm starting with the biggest setup I can own. Picked up from astrobuysell.com for £125 including a 40mm and 25mm Celestron E-Lux. Finder scope will be replaced with right angle. It has a Telrad mount (as I found out by accident) and I've alreadyt found cheap one on FB so should have that soon. Next pieces to get will be WA 6mm and 15mm. There's a small mark on the main mirror, but it doesn't seem to affect the view, and at that price I can't complain. The base also needed some attention. Vertical movement is smooth, but horizontal rotation was hindered by the bottom board being slightly bent, and rubbing the corners against the telescope base. I have added some washers between the teflon pads and it's much better. Not buttery-smooth, but I feel like that would make it too sensitive to movement, In the current condition it lets me track Jupiter easily. I guess the real test will be when I get the 6mm piece Collimating laser is also coming to make sure the mirrors are aligned after haling it home for 40 miles. Other than that it doesn't seem like it needs any serious work, so for a 20-30 year old telescope this is amazing.
Hello folks, for long I have been browsing the internet to find a suitable 10in dob and despite lack of reviews, I have decided to take the plunge with the Bresser Messier 10in Dobsonian. There was some doubt at first, especially when considering the popularity of similar scopes from Skywatcher, Meade and GSO. Even though Bresser is relatively new to the market, it has some clever features: 1. The massive 2.5in hexagonal rack and pinion focuser is very solid and the movement is smooth. Despite being only single speed, Bresser sells an a dual speed 10:1 extension. However, I find the movement precise enough and do not need the extension at the moment. 2. Optical finder scope feels a bit cheap but it is a nice upgrade over the red dot finder I had on my previous scope. 3. Rocker box style base allows disassembling the scope into two pieces (OTA and base). 4. Tube rings allows the scope to be easily balanced when adding weight + after adding a suitable dovetail plate, the OTA can be used on an equatorial mount (if you plan to upgrade to an eq mount, I would consider the 8in model, as an eq mount for the 10in would be expensive). The only negative comments I can give about the scope is the production process. There were some minor issues with the assembly with the scope as parts did not fit properly. First problem was with one hole drilled deeper (loosening the particular screw fixed the issue). Another problem was with the altitude wheel as it made the OTA to pop out from the rocker box. (A loose screw on one of the plastic pads between the box and altitude wheels was causing this. Make sure all these screws are tightened and below the surface of the pads). Lastly, I assume there must have been a mistake in the quantity of items included (I got twice as many screws for the rockerbox and 2 eyepieces instead of one, both were 25mm super plossl but the standard was a 1.25in advertised on the bresser webpage, while the other was a 2in wide angle) I did not have the opportunity to test the scope outside properly due to clouds. Update: 01.06.2017 Had the chance to try it out on the moon and jupiter to a max magnification of around 160x. The results were very sharp and detailed views. Unfortunately, clouds rolled in before it got dark enough to observe DSO's. I am waiting for clouds to clear and a package with a 42mm wide angle eyepiece and a 2in GSO 2x ED barlow to arrive next week.
Hi all I finally had a few hours without clouds and managed to capture Eta Carinae before having to turn in at a reasonable time on a work night. The sky was clear of clouds but the high humidity we have been having had a big impact on seeing and on the reflection of the lights from the nearby town. I also captured some shorter subs with the aim of 'filling in' the burnt out stars but I struggled to get acceptable results. The image below is just from the 2 min subs.
