I am working with a variances of RC back focus, the stock extenders and the Moonlite flange. Last night I could not focus with the AP reducer and no filter, and barely had focus with the Astrodon RGB filters. I ordered a 0.8" flange extender from Ron today and this should handle all focus issues, from the AP reducer to stock f/8 and other experimentation.

My entry for the challenge object NGC 2377. Also shown is mag 18.3 elliptical PGC 77220. Lodestar X2 mono, 8" f/4 Newt, alt-az, Baader C filter.

And NGC 2207/IC 2163 = VV 1155 in CMa, this time with short subs.

And finally Arp 6 = NGC 2537 = Bear's Paw. The inset shows what a single 30s sub looks like. There's a bunch of other stuff in the vicinity. I've marked a quite bright mag 18.5 quasar with a redshift of 1.99 = 9-10 billion light years distant. Having IC 2233 (a member of the Flat Galaxy Catalogue, number 730) in the shot is a bonus. This, rather unexpectedly to me, is described as a low surface brightness galaxy.

Thanks Rob for these excellent choices.

Verey nice images Martin.

In the last image NGC 2537 + IC 2233, I found at least 15 quasars in this region!

Incredible what can be resolved with the X2.

I attempted the Bear Paw and IC2233 galaxies last night. With my setup, they were pretty small in the field of view (approx. 1.5 degrees x 1.1 degrees).

10x60sec, Bin1

ASI1600MC-Cool with IDAS LPS-D1 filter

C14Edge with Hyperstar (F/2)

Captured in SharpCap and live-stacking in AstroToaster

 

First of two images is the Bear Paw and IC2233

Very nice capture, Saguaro! I am thinking about picking up an ASI071MC when my tax refund hits, along with a hyperstar for the C8. Sharpcap to Astrotoaster is awesome and I am still trying to master it which my ASI224MC, but I sure wish there was a an app for ZWO cameras like the amazing StarlightLive.

 

I spend an hour on trying to learn Sharpcap-->Astrotoaster when i have clear skies, and I always end up dropping back to StarlightLive to get some targets captured with excellent results.

 

Perhaps if I get more consistent clear skies this Spring, I will find more time for experimentation.

Agreed, very nice views you have there. So far I'm really liking Astrotoaster, even when software can do stacking it's looking to be worth the extra setup.

I got side-tracked into the very intricate RC collimation and lost many nice dark sky hours. Back to the 190MN and a very nice session to where I finished the AL Active Galactic Nulcei program in one marathon session. This is my first capture from the marathon session, 41P/Tuttle–Giacobini–Kresák. Nothing great but it is a comet capture smile.gif

Many thanks to Rob for this months targets. I am on hook for March targets, and this is way more responsibility than than I thought. I am a Tennessee guy, I volunteered so will post targets on March 1. Feb was such a short month smile.gif

I used the Night Sky Observer's Guide to pick some targets. I also used an online database that had pictures.

I PM'd someone in Canada and Australia to tell me what Declination they can see from their location to get min/max targets. That narrows it down a bit.

For the difficult target and easy target, I tried to keep the object north of -20 dec and south of 40 dec for the challenge and easy targets.

For the southern object, I just picked something that looked cool smile.gif

For a difficult target, I looked for objects that were tough but doable targets for the big dobs.
The Easy targets were rated as a 2* object in a larger scope in the Night Sky Observer's Guide. The easy can just be something interesting as you'll have both a southern and a northern target.

NGC2207 stack of 25x10s Evolution C8@F4.3, ASI290 Mono.

 

This was a really tough one for me because of the location. Between the houses looking south which is a white zone for me. You can see that in the sky background.

Please PM me when you get it up so I can pin it. Thanks for volunteering, and don't worry, I'm not going to unpin the Feb thread until yours is ready.

I don't like collimating RCs. A real pain.

 

PM me if you need help with target selection.

Last night I had exceptionally clear skies and I thought I would see what I could do from my back yard (green zone) with my old Meade 2120/LX3 Quartz at f10 with a CanonT4i (unmodded).  Polar alignment was off so I was limited to 20s exposures at iso 6400.  I thought the colors were interesting so I decided to post a screen shot even though late to the party.  The image is cropped and zoomed.
