Subject: ETX105 First Impressions Sent: Wednesday, July 2, 2003 15:14:06 From: email@example.com (Bernhard "Rendelius" Rems) after 6 weeks of waiting (during which I used a ETX90), I finally received my ETX105EC with UHTC and I thought I should give you my initial impressions. First of all, I am using this telescope from an urban location with pretty bad skies. The ETX is used in conjunction with a laptop and Astroplanner (after a lot of evaluation, I decided to use this software instead of Deepsky2003). This combination lets me actually SEE a lot of objects I wouldn't have found without it. When all you see is app. 50 stars with your naked eye, GOTO is a gift from god. I have calibrated and trained the drive with a lot of care, and my first impression is that the GOTO is more accurate than it was with the ETX 90 (and that was quite good already). For first light, I prepared a plan with 190 objects between RA 16 and 18 in Astroplanner. From these 190 objects, I have seen and recorded 25 in 70 minutes. After the initial setup, each and every object was in the FOV of the 18mm Ultima (37'). The scope performed flawlessly and gave me great views of some globular clusters, a planetary and a lot of my favourites: double stars. The optics are excellent, splitting close doubles is a joy. I have nothing but praise for the overall performance of the ETX105. The drive is quiet, accurate, and the mechanical quality is very impressive. Here's a little advice from me: Most people will find the finder placed less than convenient. I corrected that problem by simply turning the eyepiece of the finder to the left, so I have a little space between it and the main eyepiece for my nose. Compared to the ETX90, the ETX105 is expensive, but it shows in the quality of the product. The 105 is much more mature than the ETX90, in my opinion, it is less of a toy and more of a serious instrument (and again: the ETX90 is a nice telescope as well). Compared to the Nexstar 4 I used for a day: there is no comparison. The Nexstar 4 might be a good telescope regarding mechanical stability and optics, but the electronics are really inferior, in my opinion. I cannot stress enough how excellent the Astroplanner software is. It is an extremely convenient way to organize your sessions, to slew the telescope and to record your observations. My conclusion: The ETX105 is an excellent scope. Very portable, very accurate, and excellent optics. It gave me wonderful first 70 minutes, and it will open the urban sky for me. _____ Best regards, Bernhard "Rendelius" Rems CEO RPGDot Network http://www.rpgdot.com
