Recently, I've ordered f/4.2 telescope and my plan is to sell off current eyepiece lineup. This is my current eyepiece lineup for 12" f/5 telescope which has been collected during last 15 years:
- 23mm SkyWatcher Panorama (82°)
- 17mm Baader Hyperion (68°)
- 15mm SkyWatcher Panorama (82°)
- 10mm Baader Hyperion (13mm tuned with rings to 10mm)
- 7mm SkyWatcher Panorama (82°)
- 6mm SkyWatcher Planetary (58°)
- 5mm SkyWatcher Planetary (58°)
- 3.2mm SkyWatcher Planetary (58°)
I really like exit pupils in range 1.5 do 2.5 mm. My primary observing interest are galaxies, which respond very well to mention exit pupil range. That's why for most of the time I'm using 10mm Hyperion or 7mm Panorama. Those eyepieces give me best combination of FOV, magnification and contrast.
My plan is to sell of current eyepiece collection and buy new, more streamlined collection. Wide field, low power eyepiece is low on priority list so I'm looking for recommendations in 1-4mm exit pupil range (4-17mm). I'm willing to spend about 200€ per eyepiece, maybe 300€ if there is big enough performance gain.
I'm also thinking of getting barlow lens for higher magnifications instead of buying short focal eyepieces.
My train of thought goes like this:
- 18mm ES 82° Argon filled
- 11mm ES 82° Argon
- 8.8mm ES 82° Argon
- 2.5x Barlow, still deciding between 2" or 1.25" form factor
- and in far future 25mm ES 100° for wide field work
Do I need coma corrector for eyepieces in mentioned focal range (Baader MPCC Mk3)? Are there better, more cost-effective choices in mention focal range? How are ES 82° eyepieces responding to Barlow lens?
I'm also getting itched by Baader Morpheus, but they cost around 100€ more per eyepiece. Is this 50% price hike when compared to ES justified? If Morpheus works well at f/4.2 without coma correct, that could be a deal breaker and reason to switch from ES to Baader.
