Zoom Eyepiece For DSO

#1

Post by Refractordude »


Arrived at my dark site on May 10th to find that the property had been abandoned. The property is a very small apartment building that is great for stargazing at it's rear. I like the spot because there were people I could call on in case of an emergency. There was a person parked in the back, but clearly he was squatter. So I decided to find a another dark site in the area. Luckily I found a trailer park near my old spot. The park was dark enough with plenty of friendly residents. However, I will not be using the park again. I think it is best to join several astronomy clubs for my dark site observations.

I bagged a nice and long observation of M104/Sombrero galaxy first. After M104 I causally observed the night sky with my binoculars and three refactor telescopes on one mount. This was the first time I used my zoom eyepiece on DSO. Using the zoom eyepiece allowed me to find the best exit pupil, and sky background in seconds. I am thinking for galaxies I will use my zoom eyepiece exclusively. It is a budget zoom eyepiece, but it shows super sharp Moon crater edges. What do you all think about using a zoom eyepiece for galaxies?

Joining local club with access to a dark site is a great idea. Last thing you want to do is to be alone in the middle of the night in some dark questionable spot.

As for zoom EP, why not? Just remember zooms will be somewhat behind fixed FL EPs of the same tier in terms of contrast and light transmission, so if you can't resolve a faint target with a zoom, try other EPs as well.

Good idea to use a club's dark sky location rather than just winging it. If you like using a zoom that is great, but Bigz is right in pointing out some of the challenges. I pretty much use my ES 18mm 82 degree eyepiece for galaxies in both dob and frac.

Forgot to mention the 120mm aperture vs the 150mm aperture shootout on M104. The 30mm of extra aperture makes a big difference.

Best of luck . Hope you can find another good dark site. I am kinda stuck were I am so I just have to deal with it.

Sometimes its hit and miss finding a good dark site.

Regarding zooms, I am not particularly a fan. You know I am a hardcore galaxy chaser, and I had a Hyperion Mk-III several years ago. While it was convenient, I was not terribly impressed as compared to single focal length eyepieces I had at the time. One thing was the reduced AFOV and another was simply the quality of the view. Some folks talk about not having to switch out eyepieces like it is some huge inconvenience. I simply never saw that as a big deal as I can swap eyepieces and refocus quickly. I understand the allure of having multiple eyepieces in one unit, but there is always compromise somewhere when one does something like that. That said, I know many folks who swear by them and use them almost exclusively - I am just not one of them. Everyone's mileage may vary of course.

The zoom eyepiece that I am using is very sharp. I was taken aback at the sharpness of Moon craters with my zoom eyepiece. I have three eyepieces in the mail to me. These three eyepieces are made for the Moon and planets. I will do a shootout with the four eyepieces, and a little write up of the differences in the four.

Since I have my zoom, I have sold most of my other wide-angle top eyepiecs, like several Naglers and a Pentax XW. Partly because I did not use them any more, partly to finance the Leica ASPH 17.8- 8.9 mm zoom eyepiece and a matching Zeiss barlow. They were very very expensive, so I had to sell several premium eyepieces. At these costs I consider it my last eyepiece upgrade. The Leica is one of the few that starts with 60 degrees and ends just under 80 degrees. Its transparency and contrast are unusual high. Naglers are significantly less transparent and contrasty. Orthoscopic images to the edge of the field, topped only by Pentax XO5.

For DSO's it is particular interesting. A faint galaxy that you normally do not see appears while zooming in the image field. Until you reach the optimal picture. Zooming even further makes it fade again. This means that you can get the most optimal picture under all given circumstances. A new way of searching DSO's!

I presume it is a very expensive way to find out that most DSO's are at their best with an exitpupil of 1 mm here in the city and 1.5-2mm from a dark location! So I think one premium eyepiece of moderate magnification is worth more than a budget zoom eyepiece.

You are correct John, the Leica zoom is known to be in a much higher class of performance than the zoomers used by most. That said, they are not without detractors, as I've seen some who complain about edge of field brightening. One person who compared it to the Hyperion Mk-III sold the Leica and kept the Baader because he felt the Baader provided a darker background. Just goes to how we each see what we see, and we use what we find works best for us as individuals. That is as it should be. and for me presently, I will stick with my Ethoi and XWs for my galactic pursuits as they are what work best for me.

:D So the Leica was punished for its transparancy? :cry: :D

Moon and faint DSOs have different requirements. For Moon you just need sharpness, and less transmission is better since the Moon is too bright as it is.

For faint DSOs you need high transmission and contrast, and wide FOV is a plus. Budget zooms lack all three.

Useful rule of thumb is that zooms perform roughly at the same level as fixed FL EPs which are ~3x cheaper. So I would take my Baader Mark IV over Celestron X-Cel LX or Dual ED EPs, but it is not in the same class as TV Delite or Pentax XW which cost about the same as Mark IV.

Now, Leica zoom is ~$900, so I can see how it could perform at the same level as Pentax XW in particular in smaller scopes. I still suspect that Pentax XW would outperform it on very faint galaxies in large scopes. If someone can lend me Leica zoom I can do shoot out and report back. ;)

The Leica ASPH is one of those pinnacle eyepieces that other eyepieces aspire to.
I recommended one to friend last year and once he received it he has been raving about it since.

The only two zooms I currently use are the TeleVue 3-6mm with constant 50° AFOV or the Antares Series 1 5-8mm zoom with more or less constant 80° AFOV.

I sold a 5mm PentaxXW after experimenting with the Leica.( in combination with a Zeiss barlow) On planets the XW has a warmer tone (quite nice on Jupiter), on DSO I saw no differences. To my surprise the Leica had a minor advantage on the faintest visible stars. Comfort of a Pentax XW is by large better, a warm bath, less / no dewing, less / no reflections of the eye into the first lens, better shielding of extraneous light.

Hello Refractordude. A very nice report on the use of zoom eyepieces for use in DSOs. I had several zoom lenses for my cameras in the past, but underestimated them for use in telescopes. Your success with M104 (Sombrero galaxy) has me rethinking this possibility for astronomy. Thanks for your information Refractordude, and congratulations on winning the TSS VROD Award.
