Success and Failure - The Nighthawk Hunts DSO's
      #547401 - 08/06/05 12:01 AM

Well I just came in from an observing session in my back yard. Light pollution was brutal! It was hard to make out Sagitarius and Scorpius. Streetlights were shining directly on my location. Hazy clouds covered much of the sky adding to the light pollution effect. Seeing was poor - twinkling stars even at Zenith.

Equipment used:
Stellarvue Nighthawk
LV 8-24mm Zoom (20X-60X)
Orion DeepMap 600
Trusty Red Flashlight (not really needed with the streetlights)

I decided to try for a few DSO's I had hit in the past. I attempted M27 multiple times throughout the night with no success. The sky was just too bright.

Next was M57 - with the EP set at 24mm it appeared stellar, but cranked up to 8mm the ring nebula appeared as a defocused star with direct vision. With averted vision it became a smoke ring with a nice black center (a very small smoke ring).

I decided to check out the Coathanger and with the EP set at 24mm, I was able to fit the whole asterism in the FOV. Very cool! It lives up to its name.

Next on the list was the Double-Double. At 60X, both sets of stars showed elongation with occasional separation as the seeing conditions changed. Not the best I have seen it, but it was pretty none the less.

Alberio made up for that! Absolutely stunning. Deep gold and brilliant blue make this double star a must see in the night sky.

M28 was a new conquest for me and under the horrible conditions and with my smallest scope - I am kinda proud of this one. It took a bit of time to see it due to the fact that Sagitarius was litterally almost faded out due to LP. Once I locked onto M28, I bumped the power to 60X and used averted vision to check out this nice little fuzzball in the sky.

Next was M22 - Much bigger than M28! A lot easier to see and it put on a nice show in the EP. One of my favorites. No resolved stars of course under these conditions, but a really nice Glob.

I attempted M8 and M20, but I failed on both of these. The sky was terribly washed out to the South and the lightning that occasionally lit the sky wasn't helping matters.

Overall it was an incredibly productive evening with the little Stellarvue. The optics on this little scope impress me everytime I use it. Stars are beautiful hard little dots across the FOV. Under the conditions I was experiencing, I think logging a new M-Object isn't too bad.

I hope you all get to play with your scopes tonight and that you enjoy a successful night under the stars.

I'm glad to read that you had so much fun in spite of the horrible conditions Scott. Imagine the potential that this little gem has under the right conditions! Congratulations for bagging M28, especially in these dreadful conditions

I agree, Albireo is a must see in the in the summer sky. Keep us posted of the little gem's escapades

Nighthawk is a great scope. Mine gets a lot of use. I've seen what you did - except that the double-double will split using a 3.8 Orion Lanthanum and the ring will show the darker center. Can't wait to try M27 with the Nighthawk. Found it for the 1st time last week using the 102 and a 17mm Vixen LV wide. That thing was BIG. I expected a small smudge. Really enjoyable report - keep them coming.

Thanks Jacques and Weezy,

M27 is easy with the Nighthawk from a dark site - it jumps right out at you, no problem at all. My skies were milk colored, so I was fighting a losing battle. I have split the double double many times with the Nighthawk and at relatively low power, but seeing conditions wouldn't allow for a truly clean split last night. Just the wavering split I reported.

Now you keep that Nighthawk away from The Swan, big fella. I don't want one of my fav. DSOs eaten up by some raptor!

Incidentally, my mind is much better at remembering the names of celestial objects than at remembering the Messier or NGC designations. Good thing I went into literature and language studies rather than astrophysics, huh?

I have never seen thru a refractor. I am looking for a refractor in the 80 or 100 range. Your report is nice and I think the Nighthawk will be a good buy. Please keep posting your observations.
Clear Skies!

I really enjoyed your report, Scott and glad that you had productive night even with the LP. Paul laughs at me now because I'm so spoiled from the skies at my Mom's place that viewing DSO's in town seems such a drag!

Everytime I hear someone talk of a Nighthawk, I get a pang of "man, I wish I could view through one of those some day!". Thanks for sharing it with us!

MY nighthawk impressed me so much, I ended up buying a Stellarvue 102ABV. Unfortunately sky conditions here in NE TN have been horrible for over a month.

Thanks everyone. The Nighthawk continues to be my most used scope - it is so easy to grab and head out the door with it.
I'm currently waiting for the next 7 days of rain to pass.

Wow, I'm proud of you just for trying some of those targets under such frustrating conditions.. well done!!! Unless I read too fast, I didn't see any mention of a light pollution filter.. you must really enjoy impossible challenges.

Total scope rookie question : what is and how big is a Stellarvue "Nighthawk"? I know from the name that it has nice optics, but what is it?

That said, nice report Scott, I enjoyed reading it. I feel your pain about the light pollution problem. Only in my case it is the Western sky that is washed out badly - sickly grey. North and SE is bad also with noticeable light domes. My only "dark" view is NNE-NE and straight South. I compare it to a small "puzzle piece" of sky that I have with a nice dark background. The rest is a soupy mixture of dark blue, grey, and milky/smokey white.

On the bright side (no pun intended), sights like Albiero never fail to please. Even under the most washed out skies, the seperation and color contrast is usually visible, even with binoculars.

Oh, how I yearn for Orion to return. This time I have the big glass guns to throw at him!

Clear dark skies...

The Nighthawk is a 80mm F6 Achromat, with very well corrected optics. I have had my scope up to 192x using a 5x powermate and a 12.5 ortho. Also, I believe I could have gone further if I had more eyepieces available. Low power views are amazing.

I found M27 last night in the Nighthawk with the 17mm VixenWA. Guess the skies were somewhere around Mag 4 as I had to wait until I could just barely see Sagitta. Probably would have missed it if I hadn't been looking for it. UHC filter helped when I found it. We also had high thin clouds around 9:30. Darn things always seem to appear just at sunset and just in the area of the sky you want!

Thanks Carol,
I don't have a UHC or an OIII yet. Someday I will pick them up. I don't enjoy impossible challenges, I'm just kinda stuck with them. I would rather observe from the parking lot next to the Keck twins.

Mike,
Kurt is correct. The Nighthawk is a little 80mm f/6 achromat that is an absolute blast to use. Sharp optics, and a wonderful wide FOV.

Weezy,
Good snag!

I have read much about Stellarvue scopes and frankly I drool over the prospect of getting my hands on a nice beefy SV refractor. Let me ask this....Compared to the image brightness seen in a 100mm binocular, what kind of image brightness is seen in a typical low power view through an 80mm refractor like the Nighthawk?

I assume that using much higher magnifications will reach "deeper" into space, but how does an 80mm scope compare when dealing with diffuse, low surface brightness objects like dark nebulas and the like? I know I am throwing out all kinds of off-topic questions, and this probably belongs in the refractor forum, but I just had to ask.

One other thing I am curious about when it comes to a high-quality refractor with excellent glass and color correction....when viewing at really low powers, say in the 25x-40x range, what size FOV can one get using a "wide field" eyepiece? Compared to the 2.45° my binoculars offer at 25x, half of which is actually "clean" and usuable.

Thanks folks and clear dark skies...

Mike,
At 25x in the binos and 25x in the Nighthawk - the binos will crush the Nighthawk on dim fuzzy stuff. Two barrels of 100mm - the little Nighthawk can't compete with that. However - the Nighthawk has a very flat field and with a decent EP is pinpoint sharp to the edge. I get 12x and a 5 degree FOV with the 40mm Optiluxe tossed in the Nighthawk. Beautiful sweeping views of the night sky! Sharp to the edge! I have also regularly used magnifications of 160x on planets with no breakdown. Versatility is the key to the Nighthawk. It is also my H-Alpha scope when combined with my Coronado SM40. It packs neatly into a Stellarvue case (looks like a suitcase). The case holds everything but the mount. It is a keeper.

It sounds like a versatile piece of equipment. It's the repeated mention of Stellarvue's optical quality - "razor sharp edge to edge", etc. Everyone raves about it. I want that kind of optical quality in a 100mm binocular. Having said that, I realize that would require spending thousand$ of dollars on a big Fujinon cannon like Mr. Bill's. Short of that, the newer Oberwerk 25x100IF is looking like a good candidate. I hear consistent reviews that place the optical quality as "sharp" out to about 80% of the FOV. I would roughly guess that is about 10-20% better than my current Celestron 100mm binos. While it's not 100%, it's the closest I will get in the ~$500.00 range. This is all a lot to think about. Thanks for the input on the SV refractors. I'm always interested in learning about the alternatives when it comes to equipment.
